The low noise high head horizontal single-stage end-suction close-coupled pump features an integrated direct-coupled structure of motor and pump body with no coupling drive, which delivers a compact and simplified structure, easy installation and low operating noise. Optimized with proven hydraulic models, the pump achieves high energy efficiency, stable operation and a wide coverage of head and flow range. Adopting premium mechanical seal configuration, it effectively eliminates medium leakage. Widely applied in general working conditions such as building water supply and drainage, central air conditioning water circulation, industrial process water supply and municipal heating and ventilation, the pump acts as a core fluid conveying equipment with strong versatility, easy maintenance and outstanding cost performance.

- Description
- Technical Specification
The horizontal single-stage end-suction close-coupled pump is a foot-mounted, single-stage, single-suction, overhung centrifugal pump, used to handle clean water and other liquids free of solid particles whose physical and chemical properties are similar to those of water.
Applicable Standards: GB/T 5657, ISO 2858, DIN 24960.
Configuration: Horizontal, single-stage, radially split volute casing, foot-mounted, axial end suction and radial top discharge, with suction and discharge flanges of the same pressure rating. The pump has no bearings of its own and is directly coupled to the motor.
Series Design: 6 shaft-seal series cover 47 pump models, offering excellent parts commonality and interchangeability.
