Slurry pumps can be used to transport mixtures of liquids and solids in many industries in a wide range of applications, such as mine drainage, dredging of sunken lagoons and pumping of drilling mud.

Slurry pumps can also simply axially adjust the clearance between the impeller and the adjacent throat casing sealing surface. This helps to maintain pump performance when internal components begin to wear.

With the standard flush schedule, the flow is usually adjusted by compressing the packings until a few drops of water are observed leaking from the seals on the drive side. In a quench schedule the flow rate is set by adjusting the inlet valve, while a valve is used on the exhaust side to maintain the correct seal tank pressure. If the outlet water from the seal box is too hot, the flow rate is increased until the outlet water cools, while still maintaining the correct seal box pressure.

Pumping slurry can be a challenging problem, but with the right instruction, pumping and maintenance plan, you will achieve operational success.

When pumping slurry in wet sand applications, we must evaluate the abrasive particles flowing through the piping and then assess how they affect the slurry pump. If the pump is lined with poor quality rubber, the particles will not rebound effectively and, as a result, the rubber will begin to break down. The air shavings then begin to accelerate and negatively impact the efficiency of the pump, often leading to turbulence.
