Split Casing Pump Market By Type (Single-Stage, Double-Stage); By End Use (Water & Wastewater, Oil & Gas, Power Generation, Industrial Manufacturing, HVAC & Building Services, Irrigation & Agriculture); By Geography, Segment Revenue Estimation, Forecast, 2026–2032

Which Factors Are Accelerating Growth in the Split Casing Pump Market? – (Updated On: 02-Sep-2026)

The Global Split Casing Pump Market was valued at USD 5.92 billion in 2025 and is projected to reach USD 8.79 billion by 2032, growing at a CAGR of 5.8% during 2026–2032, according to Strategic Market Research. Split casing pumps are high-capacity centrifugal pumps widely used for high-flow fluid transfer. HVAC Systems circulate chilled or hot water in large commercial buildings, hospitals, and data centers; global data-centre electricity consumption is projected to rise from about 485 TWh in 2025 to 950 TWh by 2030, supporting cooling-infrastructure demand. Municipal Water Supply benefits from infrastructure modernization, with U.S. drinking-water systems requiring around USD 625 billion over 20 years, strengthening pump replacement and upgrade demand. Fire Protection remains essential, with U.S. fire departments responding to about 1.38 million fires in 2024, supporting continuous demand for reliable high-pressure pumping systems.

 

Power Generation & Industry demand remains significant as thermoelectric power plants account for about 40% of U.S. water withdrawals, largely for cooling requirements, supporting high-capacity circulation pump installations. Irrigation is another major application because agriculture accounts for approximately 72% of global freshwater withdrawals, with irrigation representing the primary use of agricultural water. Infrastructure modernization, commercial real estate growth, energy-efficiency standards, and low maintenance needs further support adoption. The ability to service internal parts without disrupting connected piping increases preference in continuous-operation industries. Together, these applications are supporting an approximately 48.5% increase in market value from 2025 to 2032, as rising water transfer, cooling, fire protection, industrial processing, and irrigation requirements accelerate demand for efficient split casing pumps.

 

Why Do Single-Stage Pumps Hold 66% of the Market While Double-Stage Designs Are Growing Faster?

Single-stage split casing pumps accounted for 66.0% of 2025 revenue, equivalent to USD 3.907 billion, and are forecast to expand at a CAGR of 5.4%. Their position reflects the prevalence of high-volume, moderate-head duties across municipal water systems, cooling-water circulation, district cooling, industrial utility water and irrigation. In these applications, adding a second hydraulic stage is frequently unnecessary. A single-stage configuration provides a comparatively straightforward rotating assembly while preserving the maintenance advantage of an axially split casing. This makes the configuration particularly suitable for facilities where pumps operate for long periods and maintenance teams need access without extensive piping disassembly.

The double-stage segment represented 34.0%, or USD 2.013 billion, in 2025 but has the faster 6.6% CAGR. Its growth is concentrated in duties where pressure and head requirements rise faster than flow requirements, including long-distance water transfer, petroleum pipelines, high-pressure firewater and selected oil and gas services. Flowserve's UZDL illustrates this operating envelope: the axially split two-stage pump uses a double-suction first-stage impeller, is designed to ISO 13709/API 610 BB1, and is rated for flows up to 3,000 m³/h, heads up to 685 metres and pressures up to 64 bar. Flowserve positions it for water pipelines, transfer, firefighting and high-pressure oil and gas duties.

The growth difference therefore has a clear commercial mechanism. Single-stage pumps remain the volume platform for large conventional pumping stations, while double-stage equipment addresses a smaller but more technically demanding set of projects with higher pressure, specification and engineering requirements. The latter can also support greater revenue per unit because materials, pressure ratings, seals, bearing arrangements and testing requirements become more demanding. The 6.6% double-stage CAGR should consequently be interpreted as a move toward higher-value engineered duties rather than evidence that double-stage pumps will displace the single-stage configuration across mainstream water and cooling applications.

 

Why Does Water & Wastewater Generate 34% of Split Casing Pump Revenue?

Water & Wastewater was the largest end-use segment in 2025 with a 34.0% share and USD 2.013 billion in revenue and is forecast to grow at 6.0% annually. The segment benefits from a combination of aging infrastructure replacement in developed economies and network expansion in large emerging cities. Pump requirements arise at raw-water intakes, treatment works, transmission mains, booster stations, wastewater collection systems and large pumping stations. Because much of this infrastructure is required to operate continuously, efficiency, reliability, serviceability and installed-life economics directly influence procurement.

U.S. water infrastructure financing remains substantial. In November 2025, the Environmental Protection Agency made USD 6.5 billion of WIFIA financing and another USD 550 million of State WIFIA financing available, while simultaneously announcing five new loan approvals covering projects in Texas, Illinois, Oregon and Florida. EPA indicates that the current financing round can support large drinking-water and wastewater investments. This financing does not translate directly into split casing pump revenue, but it materially enlarges the addressable pipeline for treatment, transmission, pumping and network-renewal equipment in North America.

Asia Pacific is producing an even more direct pump-demand signal. In July 2026, the Asian Development Bank announced a USD 230 million loan for Chennai's water and sanitation modernization programme, which will benefit about 4.5 million residents. The project includes more than 170 km of water and sewer pipelines, upgrades to seven water pumping stations and 38 sewer pumping stations, and deployment of real-time monitoring. A citywide ring-main system is also being developed to improve pressure and supply reliability. Projects of this scale create demand not only for pumps but also for controls, condition monitoring, commissioning and replacement services.

Europe provides a different demand mechanism: regulation-driven rehabilitation rather than predominantly greenfield expansion. The revised EU Urban Wastewater Treatment Directive entered into force on 1 January 2025. The European Commission reports 30,354 urban wastewater treatment plants currently operating in the EU and about 10 million Europeans still without basic sanitation access. The directive expands treatment and environmental obligations, supporting upgrades of existing collection and treatment infrastructure. As a result, European split casing demand is likely to remain replacement- and efficiency-led, supporting a lower regional CAGR than Asia Pacific but a substantial installed-base aftermarket.

 

Which End-Use Segments Are Creating the Next Increment of Pump Demand?

Industrial Manufacturing is the second-largest end-use category at 18.0% of the 2025 market, or USD 1.066 billion, with a 5.6% CAGR. Split casing pumps are used in plant cooling water, utility water, process-water circulation and large transfer systems. The commercial importance of this segment comes from the combination of new capacity and the need to replace pumps already embedded in long-life production assets. Production interruptions can cost substantially more than the pump itself, so industrial buyers increasingly evaluate reliability, maintenance access, hydraulic fit and service coverage alongside purchase price.

HVAC & Building Services generated USD 0.887 billion, or 15.0% of the market, in 2025 and is forecast to grow at 5.7%. Demand is concentrated in large facilities rather than small commercial buildings: district cooling networks, hospitals, airports, campuses, high-rise complexes and data-centre campuses can require large chilled-water or condenser-water circulation flows. This end use is supported by rising cooling and electricity consumption. The IEA's July 2026 update forecasts global electricity demand growth of 3.6% in 2026 and 3.8% in 2027, compared with 3.0% in 2025, citing industrial activity, air conditioning, heat pumps and expanding data-centre capacity as key contributors. India alone is forecast to record 7% electricity-demand growth in 2026.

Power Generation accounted for 13.0%, or USD 0.770 billion, and carries a 5.4% CAGR. The link between electricity growth and split casing pumps is principally through cooling water, circulating water, service water and auxiliary systems rather than generation equipment itself. The opportunity therefore varies substantially by plant technology. Thermal and nuclear facilities create particularly large water-handling requirements, while renewable-heavy systems alter the mix of pump demand. The 5.4% CAGR appropriately reflects this mixed picture: growing electricity requirements support new and replacement pumping capacity, but the shift in generation technologies prevents pump demand from scaling directly with total electricity consumption.

Oil & Gas contributed USD 0.651 billion, representing 11.0%, with a 5.5% CAGR. Liquid pipelines, terminals, refineries, firewater systems and hydrocarbon-transfer applications remain the most relevant split casing duties. The U.S. Energy Information Administration reported on 26 August 2026 that eight petroleum liquids pipeline projects had been completed since the beginning of 2025 and another 14 projects had been announced. One completed project, Enterprise's Bahia Pipeline, extends about 550 miles and provides 600,000 barrels per day of NGL capacity. These developments support higher-pressure engineered pumps, particularly where API-compliant specifications and low-NPSH performance are required.

The most strategically important smaller end-use segment is Irrigation & Agriculture, at USD 0.533 billion and 9.0% of 2025 revenue, because its 6.4% CAGR is the highest among end uses. FAO reports that only 23% of global cropland is equipped for irrigation, yet it generates 48% of global crop value, with irrigated yields averaging 76% above rainfed yields. More than 60% of irrigated land is already located in areas experiencing high or very high water stress. These economics support investment in reliable water-transfer equipment, although future procurement will increasingly be tied to energy and water productivity rather than indiscriminate expansion of pumping capacity.

Uzbekistan demonstrates both the opportunity and the efficiency constraint. Approximately 2.4 million hectares, or 56% of the country's irrigated land, depend on pumped water, and about 1,700 irrigation pumping stations consume 7.2 billion kWh annually—around 16% of national electricity consumption. The World Bank-supported modernization programme is explicitly intended to reduce the energy intensity of irrigation. For suppliers, this means the strongest irrigation opportunity is likely to come from pump replacement, hydraulic optimization and modernization rather than simply adding more installed horsepower.

 

How Are Energy Costs, Regulation and Digital Operation Changing Split Casing Pump Procurement?

Efficiency has become a direct purchasing criterion because operating expenditure considerably exceeds initial equipment cost over a pump's working life. Hydraulic Institute lifecycle analysis indicates that, for a typical medium-sized industrial pumping system operating for 15–20 years, the original equipment price represents about 10% of total lifecycle cost, compared with approximately 40% for energy and 25% for maintenance. For a large split casing pump running continuously, this cost structure makes efficiency deterioration, oversizing and excessive maintenance economically material even when the installed pump remains mechanically functional.

This changes supplier competition. Manufacturers are increasingly expected to offer optimized hydraulic designs, application engineering, condition information and easier field servicing. KSB's 2026 Omega redesign, for example, focuses not only on hydraulic efficiency but also on service access, bearing life, NPSH behavior and multiple material options. Sulzer similarly reported that it is developing digital solutions for condition visibility and pump-system optimization. Its Flow division recorded CHF 1.551 billion in sales in 2025, up 12.3% organically, while Water orders grew at a double-digit rate. These figures cover a broader flow-equipment portfolio, but they indicate that water equipment and lifecycle services are commercially important areas for major pump suppliers.

Efficiency requirements also increasingly enter formal procurement. In the United States, the Department of Energy requires certain covered pumps to comply with energy-conservation standards under 10 CFR 431.465 and specifies testing under 10 CFR Part 431, Subpart Y, Appendix A. The rules do not cover every split casing configuration globally, so their direct market impact should not be overstated. However, they reinforce a broader movement toward measured pump efficiency, documented performance and system-level energy evaluation.

Digitization adds a further revenue layer. Utilities increasingly specify SCADA integration, real-time operating data and performance-based O&M. Chennai's 2026 modernization programme, for example, incorporates real-time monitoring and data-driven operation alongside physical pumping-station upgrades. This favors manufacturers and service organizations that can combine rotating equipment with instrumentation, diagnostics, commissioning and aftermarket support. The resulting market is therefore shifting gradually from an equipment-only transaction toward lifecycle value, particularly for large municipal and industrial installations.

 

Why Does Asia Pacific Lead the Market With a 38% Share?

Asia Pacific held 38.0% of the global market in 2025, equivalent to USD 2.250 billion, and has the fastest regional CAGR at 6.6%. Its lead reflects the overlap of large urban water projects, industrial expansion, irrigation requirements, district cooling and new infrastructure. The approved Chennai programme is one current example: USD 230 million of ADB financing is supporting a network serving about 4.5 million people and directly includes dozens of pumping-station upgrades. At the same time, pump-dependent irrigation systems such as Uzbekistan's provide a large replacement market in which energy efficiency is becoming central to investment decisions.

North America accounted for 25.0%, or USD 1.480 billion, with a 5.3% CAGR. The market is more replacement-oriented but is supported by unusually large water-financing programmes and continuing energy-infrastructure investment. The current USD 7.05 billion WIFIA/SWIFIA funding availability strengthens municipal project pipelines, while the eight petroleum liquids pipelines completed since early 2025 and 14 additional announced projects provide a separate source of engineered pumping demand. The regional opportunity is therefore distributed between aging installed assets, compliance-led municipal spending, industrial infrastructure and high-specification energy applications.

Europe generated USD 1.302 billion, representing 22.0%, and has the lowest regional CAGR at 5.0%. Mature water and industrial infrastructure limits greenfield unit growth, but the installed base creates substantial replacement and service demand. The revised wastewater directive affects a system already containing more than 30,000 urban treatment plants, strengthening the case for modernization, efficiency improvement and equipment rehabilitation rather than capacity expansion alone. This profile supports steady revenues for suppliers with strong field-service coverage, but less volume-led growth than Asia Pacific.

Latin America represented 8.0%, or USD 0.474 billion, with a 5.9% CAGR. Water security and irrigation investment are becoming more relevant commercial drivers. On 26 August 2026, the World Bank approved a USD 186 million water-security project for Paraná, Brazil, targeting approximately 9,200 farmers across more than 130,000 hectares, water and sanitation improvements for around 60,000 rural residents, and more resilient water services for 2.2 million urban residents. Such programmes support pumps across irrigation, bulk-water movement and municipal systems, although project timing remains dependent on public-sector implementation.

Middle East & Africa held the smallest share at 7.0%, equivalent to USD 0.414 billion, but its 6.2% CAGR is the second-fastest regional rate after Asia Pacific. Water scarcity, desalination, transmission infrastructure and district cooling are the principal demand mechanisms. DEWA reported that it added 60 million imperial gallons per day of desalination capacity in Q1 2026, taking Dubai's installed desalinated-water capacity to 555 MIGD. Investments of this kind require large water-transfer and circulation systems and support demand for corrosion-resistant, high-efficiency pumps capable of continuous service.

 

How Are Competition, Aftermarket Revenue and Project Risk Shaping the Market Outlook?

Competition in split casing pumps is increasingly determined by more than hydraulic performance. Large customers compare efficiency, NPSH characteristics, materials, seal and bearing arrangements, maintainability, engineering support, testing capability and local service response. Suppliers able to cover both standardized municipal equipment and API-specified high-pressure units can address a broader revenue pool. KSB's Omega platform emphasizes municipal and industrial water applications, while Flowserve's UZDL addresses high-pressure pipeline and oil and gas duties. Sulzer's broader Flow business combines new equipment with digital and service capabilities.

Aftermarket economics are becoming particularly important. Flowserve reported USD 1.35 billion of company bookings in Q2 2026, up 26% year over year, including a record USD 696 million of aftermarket bookings. These figures are not split-casing-specific, but they illustrate why major pump manufacturers increasingly compete for lifecycle revenue rather than only original equipment sales. A split casing pump can remain in service for many years, generating demand for seals, bearings, impellers, refurbishment, efficiency upgrades, diagnostics and field service. The installed base can therefore produce recurring revenue even in mature regions where new-unit volumes grow slowly.

The principal downside to the 5.8% market forecast is project execution rather than a lack of identified pumping requirements. Large municipal, irrigation, power and industrial projects pass through engineering studies, public financing, environmental approvals, tendering, civil construction and commissioning before pump revenue is fully recognized. Sulzer reported that some large Flow projects were postponed in 2025 because of geopolitical uncertainty even as its smaller projects and Water business performed more strongly. This illustrates the timing risk that can shift orders between fiscal periods without eliminating underlying customer need.

Energy optimization creates a second, more structural constraint. Modernizing a pumping system does not always mean installing a larger pump or more pumps. Better system design, variable-speed operation, reduced network losses and improved hydraulic matching can reduce required pumping energy or installed capacity. The Uzbekistan irrigation programme demonstrates this tension particularly clearly: a large existing pump base creates replacement potential, while policy simultaneously seeks to reduce electricity consumption from pumping. Suppliers positioned around efficiency and lifecycle optimization can benefit; suppliers dependent mainly on unit-volume expansion face greater substitution and right-sizing risk.

Overall, the market's movement from USD 5.92 billion in 2025 to USD 8.79 billion by 2032 is supported by a diverse infrastructure base rather than a single end-market cycle. Single-stage pumps should remain dominant at 66.0%, but double-stage equipment should gain strategic importance through its 6.6% CAGR. Water & Wastewater remains the core revenue pool at 34.0%, while Irrigation & Agriculture provides the fastest end-use growth at 6.4%. Regionally, Asia Pacific combines the largest 2025 share, 38.0%, with the fastest CAGR, 6.6%. The strongest suppliers will be those able to convert these infrastructure requirements into efficient equipment, project engineering and long-duration aftermarket relationships while managing the timing volatility inherent in major capital projects.
