Horizontal Split Casing Pumps Market - Global Industry Size, Share, Trends, Opportunity, and Forecast, 2021-2031

The Global Horizontal Split Casing Pumps Market is projected to expand from USD 3.97 Billion in 2025 to USD 5.57 Billion by 2031, registering a CAGR of 5.81%. Defined by an axially split casing that facilitates access to the upper assembly without disrupting piping alignment, these centrifugal pumps are integral to modern fluid handling. Growth is primarily fueled by rising global investments in water and wastewater infrastructure to accommodate rapid urbanization, alongside increasing demands for high-capacity irrigation in agriculture and reliable fluid management systems within power generation and HVAC networks.

However, market expansion faces headwinds due to the substantial initial capital investment and maintenance costs associated with these complex systems compared to alternative designs. Data from Europump indicates that centrifugal pumps comprised approximately 71 percent of unit consumption in 2024, highlighting the intense competition within the sector. This market dominance compels manufacturers to justify the premium pricing of split casing models by demonstrating their superior efficiency and long-term lifecycle value against other centrifugal variants.

Market Drivers

The extensive development of municipal water and wastewater treatment infrastructure serves as the leading catalyst for the Global Horizontal Split Casing Pumps Market. Preferred for their high-flow capacity and durability, these pumps are essential for raw water intake and large-scale distribution needed to support growing urban populations. Governments are significantly increasing funding to modernize aging hydraulic networks and flood control systems; notably, the Ministry of Water Resources reported in December 2024 that China invested a record 1.35 trillion yuan in water conservancy facilities, directly supporting the deployment of large-capacity pumping stations.

Additionally, the industrial sector's preference for ease of maintenance and extended service life continues to drive adoption, distinguishing split casing designs from other centrifugal options. The axially split architecture allows for rapid maintenance access without disturbing piping, effectively reducing downtime and operational costs. This value is reflected in strong aftermarket performance, with KSB SE & Co. KGaA reporting an 11.0 percent rise in service segment revenue to €944 million in their 2023 Annual Report, while Ebara Corporation saw an 11.5 percent revenue increase in 2024, driven by robust infrastructure and industrial demand.

Market Challenges

A primary obstacle to market growth is the high upfront capital expenditure and ongoing operational costs required for horizontal split casing pumps. The complex engineering and material specifications result in a premium price point that often deters budget-conscious buyers, particularly in cost-sensitive sectors like municipal water treatment and agriculture. Consequently, procurement teams may prioritize short-term savings, opting for less expensive centrifugal alternatives or deferring necessary upgrades, which limits the addressable market for these advanced pump models.

This hesitation to invest in capital-intensive machinery is further exacerbated by the challenging economic climate affecting the broader industrial sector. High interest rates and inflationary pressures on raw materials have constrained capital budgets, impacting purchasing power. According to VDMA, price-adjusted production output for machinery and equipment in the European Union declined by 7 percent in 2024 due to weak demand and rising costs, illustrating how financial constraints are forcing industrial facilities to reduce spending on premium heavy-duty components to preserve liquidity.

Market Trends

The integration of IIoT and smart sensors for real-time condition monitoring is transforming the Global Horizontal Split Casing Pumps Market by converting standard pumps into intelligent, data-driven systems. Manufacturers are embedding advanced diagnostics to enable predictive maintenance, significantly reducing unplanned downtime and operational risks. This digital evolution is gaining strong commercial traction, as evidenced by Smart Water Magazine's February 2025 report noting that Xylem Inc.'s revenue rose 16 percent to $8.6 billion in 2024, largely driven by its strategic focus on digitalization and intelligent water management technologies.

Simultaneously, there is an increasing adoption of corrosion-resistant alloys, such as duplex stainless steels, to handle harsh environments, particularly within the power generation sector. As industrial operations encounter more extreme conditions, the demand for specialized metallurgies that offer superior durability over traditional materials is surging. This trend is highlighted by Flowserve Corporation's February 2025 report, which cited a year-over-year increase of more than 40 percent in power bookings, including over $110 million in nuclear awards, underscoring the critical need for robust, high-specification pumping solutions.
