Rotary Piston Pump
Rotary Piston Pump
- (1) Stable and continuous operation at high pressures (low vacuum zones).
- (2) Withstanding operation characterized by severe repetition.
- (3) Robust exhaust valve.
- (4) Sight glass for observing oil circulation.
- (5) Oil gauge for observing oil level.
- (6) Efficient oil separator.
- (7) Easy to make an inspection and maintain the exhaust valve storage.
- (8) Easy cleaning oil tank because of a large cleanout.
- (9) Quickly discharge the oil accumulated in oil tanks via the oil drain valve.
- (10) Easily maintained shaft sealing assembly.
The pumps are mechanically acting vacuum pumps on the principle of a rotary piston or plunger. The pumps are manufactured as single and two-stage pumps. The pumps are single-stage pumps with a pumping speed of 250 m3/h (147cfm) and an ultimate pressure of 0,04 mbar (0.024 Torr). The DK pumps are two-stage pumps with a pumping speed of 200 m3/h (118 cfm) and an ultimate pressure of 5•10-4 mbar (3•10-4 Torr)
Applications :-
- Piston pumps can be used to move liquids or compressed gases and can also pump viscous media and media containing solid particles.
- Piston pumps are used for water and oil hydraulics, industrial processing equipment, high pressure cleaning and the pumping of liquids.
