Piston dosing pump
“A – I ” type piston metering pumps are suitable for use when the liquid to dose is non abrasive solution and when high pressure is required. The PDP series are manufactured according to API standard 675. Stroke adjustment can be done manually, electrically (4-20mA; Profibus) and pneumatically.
Accuracy is better than 1% from 10 to 100%. Different multiple head units are available on request. A wide range of material like Hastelloy,Alloy,PTFE are available. All the series can be ATEX certified.
