1/3 hp submersible sump pump with vertical manufacturer

Positive displacement slurry pumps with limited capacity to deliver high head are used to pump slurry through pipes with very high solids concentrations.

From an operational point of view the stuffing box is different as it requires some leakage to ensure lubrication and to prevent heat build up. The mechanical seal box should be leak free.

Types of damage to slurry pumps

The slurry pump is mainly used in the mining industry, its wear resistance is strong. So It conveys slurry that containing slag, but it can conveys mud. The mud pump is usually made of cast iron, the wear resistance of the pump is low. So the mud pumps often used for conveying mud or slurry containing suspended particles.

As wear is a function of speed, slurry pumps should be operated at the lowest possible speed; units typically run at 1,200 rpm or less. Often, direct coupling between the pump and a low-speed motor or other drive makes the most sense. On the other hand, many other applications favour gearboxes to meet the required speed and operating point. In services where variable flow rates are required, variable frequency drives are used to provide the necessary continuous speed variation.
