Problem: A longtime pumper truck manufacturer was experiencing constant overheating and failure of washdown pumps due to cycling. The manufacturer had been using a pressure switch, which was required because the pump they were using would fail if it was left on but being used. Leaks in the lines and valves would constantly turn the pump on and off. Cycling was also causing the pressure switch to fail.

Solution: DC10 centrifugal pumps from MTH Pumps (with the use of a bypass line) are designed to run for up to 2 hours at shut-off without any heat or mechanical seal problems. This eliminates the need for valves and pressure switches, reducing costs and the number of things that can go wrong in the field. It is manufactured with all-cast stainless steel wetted parts with a standard dry run seal for reliability.

Result: After more than 5 years of service, the customer has had an almost flawless record of no failures with the pumps. 630-552-4115; www.mthpumps.com.
