Welcome to Credo, We are an Industrial Water Pump Manufacturer.
Vertical Split Case Pump


The vertical split case pump is a high-performance centrifugal pump with a vertically split casing and double volute design, offering excellent hydraulic efficiency, reduced shaft loads, and stable operation. Compared with horizontal pumps, it provides a compact footprint and easy maintenance, as internal components can be accessed without disturbing piping. With durable construction, reliable performance, and flexible material options, this pump is widely used for water supply, cooling, and industrial fluid transport in various industries.
Key Design Features
Vertically Split Casing: The casing is divided vertically, making inspection, maintenance, and component replacement faster and easier compared to other pump designs.
Double Volute Design: Reduces radial thrust on the shaft, ensures smoother operation, and extends the life of bearings and seals.
Compact Footprint: Space-saving vertical arrangement is ideal for facilities where floor space is limited.
High Reliability: Designed for continuous duty in harsh environments, with strong bearings and high-quality materials such as cast iron, ductile iron, stainless steel, or bronze.
Flexible Operating Range: Capable of handling high flow rates and a variety of fluids, from clean water to industrial process liquids.
