Rotary Piston Pump
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)
(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.
Application Of Rotary Piston Pump
• 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.
