The membrane hand pump can be used universally, for example as a dirty water pump. It works with ball valves and is particularly suitable as an additional pump for sewage lifting systems. The valve seats can be cleaned by unscrewing inspection flaps without tools. The pump M 40 is made of cast iron. The valve balls and the diaphragm are oil resistant.
