Important Factors When Selecting A Slurry Pump

Choosing the right slurry pump can be a daunting task. Slurry pumps can be found in almost all industries and play a vital role in many processes. LONGWEI introduces you how to choose the right slurry pump.

Mud pump power size

Determining the right slurry pump size and power requirements for your application is critical. Depending on the abrasiveness of the slurry, it is important to select a pump size that will allow the pump to run at a slow enough speed to extend the life of the slurry pump. The ideal RPM to run a slurry pump is 900-1200 RPM. once this speed is started to be exceeded, the life of the pump is significantly shortened as the wear points in the slurry pump are essentially blasted with sand.

Mud pump seal

Depending on the abrasive nature of the slurry, it is important to choose the ideal seal. The slurry pump seal should have a hardened surface made of silicon carbide or tungsten carbide. Vortex pumps use a patented seal technology which uses a double mechanical seal device and a separate seal flushing system. This allows the sealing surface to be cooled at all times without causing the slurry to overheat the seal and crack the surface.

Slurry pump design

The design of a slurry pump is critical to ensure that the abrasive and often corrosive aspects of the slurry do not damage the impeller. In addition, slurries and sludges can contain large amounts of unforeseen solids, which will inevitably clog many types of pumps. Since most centrifugal pumps have impellers with close tolerances to the worm gear, the abrasive and sometimes corrosive nature of the slurry can quickly wear the worm gear and destroy the tolerances. This in turn can cause the pump to lose its suction capacity. This can lead to extensive downtime of the slurry pump as well as expensive maintenance and spare parts.

Deployment method

Determining the ideal deployment of a slurry pump is an important step in determining the ideal setup. The three main slurry pump deployment methods are submersible pumps, submerged suction pumps and self-priming pumps.

1,Submersible deployment

A pump that is completely submerged in a fluid is called a submersible pump. By submerging in the fluid to be pumped, no filling is required.

2,Overflow pumping deployment

For overflow suction pumps, the fluid to be pumped is located above the pump. When the pump is located below, gravity can feed the fluid into the pump suction port and keep the pump in the start-up condition.

3,Self-starting deployment

With a self-priming device, the pump and power unit are not submerged. The suction chamber enters the slurry and the unit acts like an oversized wet or dry vacuum. Can be mounted on a trailer for added mobility.

Material of construction

Choosing the right material for your mud pump is another key process in determining the right pump to handle your mud. If the slurry is highly abrasive with a neutral pH, then the best material of construction is high chromium. This metallurgy has the highest Brinell hardness and can withstand the abrasiveness of the slurry. On the other hand, if the slurry is not only abrasive, but also has a low pH, a duplex stainless steel construction is preferable. This material is best suited for slurry pumps to withstand corrosive materials (such as acids) while still having a high Brinell concentration.
