Slurry Pump Failures

Top 6 Causes of Slurry Pump Problems KSB SE

Replace worn parts on time to prevent pump failure before it occurs. Ensure the pump is operating at its best efficiency point. Pumps are seldom operated at their best efficiency point (BEP), which is the one point on the performance curve that is the optimal operating point for the pump at a given duty.

Slurry Pumping Handbook AU Pumps! That's what it's about

Slurry Pumping Handbook AU Page 6 Issued: Feb 2000 The centrifugal slurry pump must be designed to allow the passage of abrasive particles which can at time be extremely large. The largest Warman slurry pump, for example, can pump particles up to 530mm in spherical size. Slurry pumps therefore need much wider and heavier impellers to

Process Engineering Avoid trouble with slurries

Nov 01, 2006· An additional consideration for slurry systems is re-starting agitation after a power failure. Agitators are often unable to re-suspend the solids once they have settled. Most pumps are designed for light slurry loads and can t handle the settled solids, usually due to the high viscosity. Sparging with a liquid is the best solution for agitation.

Choosing a Slurry Pump Features The Chemical Engineer

Summary. Pumping of slurries can often lead to blockages or equipment failure. The job of the designer is to assess all the factors of each situation, including client and existing site preferences to design a system and select a pump which is robust enough to minimise blockages and makes maintenance for operators as easy as capital would permit whilst providing a safe system of work.
