Product Description

                                                       What is a Dredge Pump

A dredge pump is a horizontal centrifugal pump and is the heartbeat of a dredge. It is designed to handle
abrasive granular materials and solids of limited size in suspension. Without the dredge pump, a cutter
suction dredge would not be able to transport slurry.

The dredge pump is designed to take in sediment, debris, and other harmful materials from the surface floor
into a suction pipe, carrying the material to a discharge site through a pipeline. The pump must be able to
handle common solid fragments of various sizes that are capable of passing through the pump, minimizing
downtime required for cleaning.

                                                            How do  dredge pumps work?

The dredge pump contains a pump casing and an impeller. The impeller is mounted inside the pump casing
and is attached to the drive motor via gearbox and shaft. The frontal portion of the pump casing is sealed
using a suction cover, connecting directly to the dredge's suction pipe. The dredge pump's discharge is
positioned near the top of the dredge pump and is connected to a separate discharge line.

The impeller is considered the core of a dredge pump and is similar to a fan that forces out air creating a
centrifugal suction force. At the suction pipe, this vacuum absorbs the slurry and transports the material
through the discharge pipeline.

 

Detailed Photos

WN series of dredging pump,which is designed and researched by our company--E-Touch ENGINEERING
is one new type dredging pump,making full use of advanced CAD software,aiming to China'sriver,lake and
sea situation,they are in great need to dredge and fill hydraulically.

This series of dredging pump has characteristic features:easy installation,long life service,high efficiency,
reliable bearing lining and good economical efficiency...This type of pump can meet dredging ship's
requirements completely and each set of dredging pump has passed the inspection issued by CCS.

The hydraulic design of our pumps have been analysed with Computational Fluid Dynamics and optimized
with dredging and slurry operation in mind. The design is further fine-tuned to reduce local wear effects.
The wet parts of slurry pump is made of high chromium alloy, or abrasive rubber so they are suitable for the
liquid with solid, and with acid or alkali, this make the slurry pump powerful and widely used.
