420m Head 300-440m3/H Horizontal Multi Stage Pump 4 Stage Water Pump

Horizontal Ring Section Multistage Centrifugal Water Pump D360-40X5


Description

The D series Multistage Ring Section Centrifugal Water Pump is a utility-grade, high-pressure, ring section pump with heavy duty, segmental ring, diffuser design. Axial thrust balance device with stacked rotor construction. Suitable for boiler feed pump and high building, long distance water transferring.


Structure Design

Horizontal, radially split, ring section pump with radial impellers, single or double flow entry, multistage. The stages are sealed against each other by O rings or by metallic sealing faces and fastened by tie bolts.


Balancing Device
Thrust compensation by the hydraulic balancing device located at the discharge side. Balancing by disc or double piston.


The balancing device on centrifugal pumps is designed to fully or partially compensate axial thrust generated by the pump rotor. Designs incorporating a single balance drum or double drum require a thrust bearing to absorb the residual thrust.


When the pump is in operation, the balancing device requires a certain amount of balancing flow through the clearance gap between the balancing device's rotating and non-rotating parts. The balance flow is subjected to considerable throttling on its way through the gap.

Features and Benefits
* Greater reliability from radially split pressure casings, ensuring overall pump concentricity and rotor alignment.
* Improved service life and tolerance to changing conditions due to precision-cast diffusers that equalize radial loads and increase bearing, wear ring and seal life.
* Decreased maintenance costs and longer service intervals enabled by heavy-duty rotor with short bearing spans, which minimizes deflection.
* Precise hydraulic configuration made possible by the modular segmental ring diffuser design plus numerous options.

Top of its class efficiency to ensure lowest specific power consumption per produced cubic meter of water.
