Our Featured Dredge Pumps

HDG Sand&Gravel Pump

HDG Gravel pumps are equivalent with Warman G, GH pumps, this range is the world’s standard for dredge and gravel applications. The range provides excellent wear life while maintaining efficiency during the wear cycle and the best total operating cost. A wide variety of shaft seals provide a perfect fit for a range of applications.
Construction of this pump is of single casing connected by means of clamp bands and wide wet-passage. They are designed to handle very large particles for gravel and dredging operations, could continuously handle the most difficult higher abrasive slurry, containing solids too large to be pumped by a standard slurry pump.

Submerged &Suction Sand Pump (ZJQ )

Submerged &Suction Sand Pump is a kind of full submersible slurry pump. The motor of the same shaft and the pump work together immersed in water. The wear-resistant parts of this series of pumps are made of chrome alloy with high wear resistance.
ZJQ series submersible slurry pump is mainly composed of three parts: pump head, motor and sealing parts. The hydraulic part adopts advanced design method. The pre-set stirring impeller of the pump can spray sediment and warpage into the high concentration slurry.
The unique sealing device can effectively balance the internal and external oil and protect the reliability of the mechanical seal. The motor adopts protection devices, such as overheating protection test and water detection protection, to ensure long-term good work under poor working conditions.

Submersible Slurry Sand Pumps

ZJQ mine flameproof submersible slag slurry electric pump is a new type of high efficiency anti-abrasion pump developed by our company. In the hydraulic design, structural design and wear-resistant materials used, the advantages of the same kind of products at home and abroad are comprehensively applied and innovated, with high efficiency and energy saving, small vibration, low noise, reliable operation, long service life, easy maintenance and other characteristics.

Widely used in electric power, metallurgy, coal, building materials and other industries to transport slurry containing solid particles.
Because the pump inlet is installed with a stirring wheel, the mud at the bottom of the inlet can be stirred up and pumped out at work; Reduce the sedimentation of the sewage pond (or mud pond), ensuring the effective volume of the sewage pond.

Built-in electric pump, water flows through the motor sandwich, effectively prolonging the service life of the electric pump. This pump is especially suitable for underground coal mine water silo cleaning, belt conveyance roadway coal slime tank drainage and main shaft bottom drainage. It can realize automatic drainage of vertical shaft, inclined shaft and coal slime pool at the bottom of shaft.

Buying counterfeit parts: Counterfeit parts may not meet the same quality standards as genuine parts and may not function properly, leading to equipment failure.
Not checking compatibility: Not ensuring that the spare parts are compatible with the make and model of the pump can lead to improper installation and malfunction.
Not considering the application: Choosing spare parts that are not designed for the specific application can lead to poor performance and equipment failure.
Not considering quality: Choosing low-quality spare parts can lead to frequent breakdowns and increased maintenance costs.
Not considering the supplier's reliability: Choosing a supplier who has a poor quality. Low price has its reason. Using unqualified raw material which could not reach standard content.
Not considering after-sale service: Choosing a supplier who can't provide technical support and assistance with installation and maintenance can lead to poor performance of the equipment and increase maintenance costs.

The Benefits of Investing in a Durable Slurry Pump

Investing in a durable slurry pump is essential for industries that require the transfer of abrasive and corrosive liquids, such as mining, construction, and chemical processing.

1.What information is needed to select my slurry pump?

You need the information below:
Liquid name:___
Capacity:___ m3/hr
Head: ___ m
PH:___
Specific of gravity:___
Voltage:___V, Frequency:___HZ

2.What should I consider when purchase a slurry pump?

There are two major considerations when selecting a slurry pump: the impeller and the casing. The impeller should have a large enough passageway so that the solid particles, no matter their size, can pass through without clogging. The casing of the pump, which handles the pressure, should have larger gaps between the impeller and the cut-water tongue, to reduce wear and prevent large solid particles from getting stuck.It’s important you take note of the materials of construction, this includes metal and/or rubber pump lines and metal casing. A metal and/or rubber pump liner will combat erosion from the solid particles. The metal casing will resist erosion caused by the increased pressure and circulation.

3.How long is my slurry pump’s service life?

We are not able to answer you a exact period. Pump wear is affected by the pump design, the abrasive nature of your slurry, the specifics of the application or duty conditions, the application method and whether the selected pump size is suitable for your project parameters.Our HEDUN heavy duty slurry pumps are designed for continuous pumping of highly abrasive, high-density slurries with minimal maintenance,and our professional engineers will select the ideal pump as per your parameters.
