Seminar S2

Maintenance and repair of metering pumps

The 2.5-day seminar is intended for personell which has to install, assemble, commission, operate, maintain and repair LEWA metering pumps.

Metering pumps are an important component in many industries that require accurate metering of fluids or liquefied gases. Training participants learn the theoretical basics of our reciprocating positive displacement pumps and how they work. Assembly and disassembly and commissioning of a pump can be practiced on our training models. If the diaphragm pump or pumping plant malfunctions or fails, a thorough fault analysis is essential. Operators learn to identify potential problems and take appropriate action. Our trainers have many years of experience and can communicate complex interrelationships in an understandable and practical way at our training facilities.
