application

Single stage end suction centrifugal pump is suitable for conveying clean water, or liquid with physical and chemical properties similar to water without solid particles.
- Industrial use: used to transport coolant, condensate, mildly corrosive liquids, etc. Widely used in factories and mines.
- Building water supply: high-rise building booster water supply, municipal water supply and drainage.
- Agricultural irrigation: irrigation, drainage, irrigation canal management.
- Other industries: HVAC system, boiler water supply, fire sprinkler system.
The same specification of horizontal end suction pump can achieve the change of performance parameters by cutting the outer diameter of the impeller: the normal speed of the pump is 1450RPM and 2900RPM. If it needs to run at the maximum speed of 3550RPM (60hz power supply or equipped with gasoline/diesel engine), the outer impeller needs to be customized, please contact us for help.
Structure Description
- The pump body and the motor adopt a coaxial design, which occupies a small area and is easy to install and maintain.
- The overall design of the pump meets international standards and has a beautiful appearance.
- The single stage end suction centrifugal pump is cast by the vortex chamber, the foot, and the inlet and outlet flanges.
- Pump body
- The horizontal end suction pump is rear-opening. When disassembling the pump cover and the impeller, there is no need to disassemble the suction and discharge pipes. The pump is directly driven by the motor or the internal combustion engine (diesel engine, gasoline engine) through an elastic coupling.
- The shaft seal of the single stage end suction centrifugal pump is divided into: packing type (P) and machine seal type (M).
- The machine seal type has three forms: M1, M2, and M3. Among them, the M2 type adopts a balanced machine seal, which is used for the use requirements of the pump working pressure greater than 1.6MPa.

Installation Notes
The installation of single stage end suction centrifugal pump has an important impact on the operation and service life of the pump, so installation and calibration must be carried out carefully.
- Remove oil stains and dirt from the base and place the base on the foundation.
- Check the levelness of the base with a level.
- Pour cement into the base and anchor bolt holes.
- After the cement is dry, check whether the base and anchor bolt holes are loose, tighten the anchor bolts if appropriate, and check the level again.
- Clean the support plane of the base, the plane of the pump foot and the motor foot, and install the horizontal end suction pump and motor on the base.
- A certain gap should be maintained between the couplings, and check whether the center lines of the pump shaft and the motor shaft are consistent. Thin shims can be used to adjust them to be concentric.
