It is a horizontal multistage high-pressure pump with a power of 55 kW. According to the customer's request, the pump body is customized in blue

 The Rwandan customer visited our factory before shipment to inspect the facilities and witness the pump testing process. They were very satisfied with the pump's manufacturing process and witnessed the entire testing procedure, confirming that the pump's parameters fully met their requirements. 

Introduction to D series horizontal multi-stage centrifugal pump 

Overview 

This series of pump is of sub-horizontal, multi-stage single-suction and centrifugal, using state-recommended hydro-module. The pump is efficient, reliable, and durable with low noise performance, easy maintenance and wide scope of usages.

Our pump is applicable to deliver those fluid without solid, particles or any other suspended stuff, water for instance. While oily and corrosive or solid-contained fluid can be pumped by means of material modification, sealing methods, and cooling system adding.

The max. inlet pressure shall be 0.6MPa.

 

D type applicable:

 

Used for transmission of water free of solid particles and temperature below 80 ℃, or similar physical and chemical liquid. Suitable for mining, mill and city water supply and drainage.

 

 

Performance Range：

 

Inlet and outlet diameter of the pump: 40–300mm

Capacity Q：3.75～850m³/h
Head H：19～816m

 

Product features

That suction inlet is set horizontally while discharging outlet vertically is one of peculiarities for D horizontal, single suction, segmental multistage pumps. The segments of suction, middle, discharging are connected by means of bolt. The head employs the stages of the pump.
