Piston dosing pump

“A” type piston metering pumps are suitable for use when the liquid to dose is non abrasive solution and when high pressure is 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 (4-20 mA; Profibus) and pneumatically. Different multiple head units are available on request. All the series can be ATEX certified.
