Mechanical diaphragm dosing pump

“D” type mechanical diaphragm metering pumps are suitable for use when the liquid to dose contains small suspended solids and when high pressure is not required. The gearbox is a standard wormwheel reduction system coupled with a vertical mounted B14 shaped electric motor in accordance with UNEL-MEC specification. The mechanism for variation of the stroke length is a positive stroke spring return operated by an eccentric. Stroke adjustment can be done manually, electrically (4-20mA; Profibus) and pneumatically. Different multiple head units are available on request. All the series can be ATEX certified.
