S Sh Horizontal Double Suction Centrifugal Split Case Pump

A high-efficiency horizontal, single-stage double-suction split-case centrifugal pump engineered for large-capacity water transfer and industrial water systems. The split-case design provides easy access to the rotating assembly for inspection and maintenance: lifting the pump cover allows removal of the impeller, shaft and seals without disconnecting suction/discharge piping or the driver, minimizing downtime and service labor.

Key features and benefits:

• Split-case, double-suction impeller for smooth flow, low radial load and stable operation at high flow rates.
• Single-stage construction optimized for energy-efficient performance across a wide flow range.
• Removable pump cover and shaft assembly for rapid maintenance and inspection without pipeline or motor removal.
• Bottom-located suction inlet and outlet around the shaft for balanced flow and simplified installation.
• Configurable materials and mechanical seal options to accommodate clean water and, with material changes, abrasive or corrosive liquids.

Typical applications:

• Municipal and industrial water supply
• Power station condensate and cooling water systems
• Large-scale irrigation and drainage projects
• Mine dewatering and factory process water
• Any application requiring high flow, moderate head pumping of clean water or similarly behaving liquids

Performance ranges (typical):

• Flow rate: 80 – 15,000 m3/h
• Design head: 19 – 100 m
• Rotational speed: 1,450 – 2,900 rpm
• Inlet / outlet diameters: from 25 to 500 mm
• Liquid temperature range: approximately -40 to +80 °C
• Maximum working pressure: ≤ 1.6 MPa

Model code explanation (example: "300 S 90 A"):

• 300 — suction diameter in mm
• S — single-stage double-suction split-case pump type
• 90 — design head in meters
• A — impeller trimmed once (first trimming)

Supply options and customization:

• Standard pump assemblies include pump body, pump cover, shaft, impeller, seal ring, shaft sleeve and bearings.
• Materials, seal types and clearances can be adapted for abrasive slurries or corrosive liquids on request.

This pump is suited for projects requiring reliable, service-friendly, high-flow pumping where low vibration, balanced hydraulic loading and straightforward maintenance are priorities.
