In this article, we will mainly introduce the wide application of Shear Pump manufactured by GN Solids Control.


As we know, Shear Pump is specially used for shearing the high-molecular polymer and bentonite, which need to be fully sheared by the Shear pump before entering the drilling fluids system, then their functions could be fully played and improve the property of drilling fluids. If the high-molecular polymer and bentonite are not fully sheared, the polymer will block the screen in the first time circulation and massive polymer will be lost and increase the drilling cost.


As what showed in below picture, GNJQB series Shear Pump is specially designed for meeting to quickly configure and get high-performance drilling fluids. After been fully sheared by the Shear Pump, the high-molecular polymer could be more easily mixed and hydrated in the fluids and shorten the configuration time, thus improving the quality and efficiency of configuration drilling fluids.


GN Shear Pump

The Advantages of GN Shear Pump

1). Belt-driven and has a compact structure;

2). Special design with the impeller, a wider flow passage and smooth vanes design make the pump has a larger flow area and fluids could pass smoothly. Compared with similar products, the work efficiency is effectively improved and energy is saved more than 10%.

3). Thicker pump shell than normal one, with rational flow rate and occurring less turbulence;

4). The pump shell and impeller are made of high wear resistant cast irons with longer service life;

5). The shear pump has higher strength that can reduce shaft deflection and extend the service life of seals;

6). The Shaft is lubricated by lubricants or grease. The oil seal is made of special structure and material, which is suitable for high and low temperatures and complicated environment;

7). Front opening structure design, convenient for installation, repair and maintenance.

Mud transfering centrifugal pump in GN’s product line range from 20~320m3 by flow. This centrifugal pump is designed to handle abrasive, viscous and corrosive fluids in drilling or industrial slurry applications. Comparing with conventional pumps, GN’s centrifugal pump has an exceptional performance by large volume, high temperature capabilities and easer to maintenance.

GN Mud Transfering Centrifugal Pump

Centrifugal Pump Structure and Parameters

With outlet 2″-6″, GN’s centrifugal pump has a head capacity range from 12m to 62m. It could be working well in the tempreture span of 100℃(-40℃~60℃).
Strong and thick pump housing design of ring runner shape to eliminate the turbulence and cavitation within the pump housing. The small distance between the impeller and the housing to be the same at all points as the centrifugal design.
In order to reduce the turbulence, lower radial and thrust loads, and provides a smooth flow of fluid through the pump, the impeller is designed for open-vane. Aslo thie design allow fluid leaving the impeller to blend with recirculating fluid to reduce abrasive wear of the casing. By using O-type oil seal to protect the no exposed shaft threads, the lifetime of the pump largely extended.
Worth to mention is that all GN centrifugal pump is using mechnical seal. All metal parts are made of 316 stainless steel. Elastic part are manufactured from viton. Both rotating and stationary seal faces are tungsten carbide.

Centrifugal Pump Functions

For drilling application, GN centrifugal pump could be used for mud transfering, mud mixing and shearing operations, desanding and deislting, degassing, supercharging, centrifugal feed, mud cooling tower and wash down.

In solids control system, GN’s centrifugal pump has below applications:

  • Mud transfering  By locating the centrifugal pump on the mud tank skid, the drilling mud could be transferred from tank shaker compartment to the Mud Cleaner for treatment by hydrocyclone.
  • Mud Mixing   Combined with a venturi type hopper,  the centrifugal pump could be used to shear the bentonite powders and mix the new clean drilling mud.
  • Charging pump   Connected with the mud pump unit, centrifugal pump could transfer the clean mud to mud pump, then from mud pump back to the drill rig.

Besides the mud transfering pump, GN could also offer slurry pump, mono pump for Decanter Centrifuge, and shearing pump for shearing large drilling fluids chemical particles. For more information about GN mud transfering centrifugal pump, please leave a message or contact with us.

In GN products line, centrifugal pump is one of the main equipments that got many order for GN. All the working for transfering the mud in recycling system is done by pump.

Centrifugal pump

Mud cleaner is one type equipment which need centrifugal pump transfer mud into the cyclone to complete its mission. In mud mixing unit, centrifugal pump could be used to transfer the mud into all the storage tank. Mud pump also need centrifugal pump to feed drilling mud.

Bare Pump


GN’s centrifugal pump is interchangeable with famous NOV Mission pump which is a very good selling point. Welcome contact with GN for more information about this centrifugal pump.

GN produced solids control equipments(such as shale shaker, vacuum degasser, desander, desilter,drilling fluids centrifuge, centrifugal pump, mud tank, etc) with high quality and competitive price. Our principle is “Quality first, Price second”.

 For solids control equipments, there are 100 prices,and 100 quality in China.

  If we divide China products quality into:     A>B>C>D

   And divide China products price into:      A>B>C>D   

 And GN’s market strategy is to provide Quality A products with Price B.We look to profit from more orders,not to have high profit in few orders.

Shale Shaker

Shale Shaker

For example, one client found a shale shaker with only 70% price than GN’s, so he is not interested in working with GN, and go for the cheaper products, but after using, it always has problem of mud overflow. Maybe the problem is mud or shaker screens, or maybe it is because of shale shaker or improper operation. Until now he still have trouble of well working of the shale shaker.
