The dosing-pump unit DPA-003 and DPA-003-Z are designed for operation in conditions of pressure up to 200 bars and discharge up to 80 l/h.
DPA-003-Z is actuated by compressed air while DPA-003 is actated by el. Motor. If the DPA-003 unit works in explosive mixture, the unit can be equipped with an explosion proof electric motor. The dosing pump unit has no mobile parts outside the housing, which guarantees operator safety during control or setting working conditions.
Both types are intended for operation in food processing, pharmaceutical, oil and other industry where precise regulation of media dosing is required. The supply regulation is performed by changing the piston stroke length by the regulation screw with vernier divided by 0,25% of maximum supply. The number of strokes is constant.
Dosing pumps are equipped with with measuring pointer from which the amount [%] of dosing pump discharge can be read.
