Rotary Vane Pump

VP Series

VP Series pumps are rugged mechanical oil-sealed pumps with speeds ranging from 8 to 300 m3/hr(5 to 178 CFM). Compact and quiet, they feature advanced lubrication circuits, high reliability, and accessories to suit specific application needs.

Vane pump has become industry's standard choice for laboratory and light industrial application. Known for its rapid pumping and ability to handle vapor. Vane pumps are designed for reliable and long-term opeation. Single phase motors are equiped with thermal overload protection at no extra charge. Distinguished by high pumping speed even in low pressure ranges. Very quick pump-down time. It does not require regular maintenance other than oilchange at service intervals.Shipping includes: 1 litre of oil, KF25 center ring and O-Ring. Supplied at no extra charge. Fomblin oil, if required, must be purchased separately for PFPE pumps.

Reliable system with anti suck-back protection

Every pump has protection devices to prevent oil and air suck-back into the vacuum system if the pump stops while under vacuum. A variety of protection devices are used, depending on the pump size and cost, but emphasis is always placed on reliability and simplicity. When you use gas ballast on some of the pumps, you must use a solenoid operated gas ballast control valve to prevent air suck-back.

Positive Pressure Oil Lubrication

The pumps incorporate a positive pressure oil lubrication system to ensure correct lubrication to prevent oil starvation with high gas loads. An integral oil pump ensures that oil flow is pumped adequately throughout the stator/rotor assembly at all times. This oil lubrication system means that the level of oil in the reservoir is less criticalthan with other pump designs. Pump can operate at 50-70% of the maximum oil level . A sight glass allows convenient monitoring of the level.

PV Series

Gas Ballast

The pump has a gas ballast valve. The valve is used to introduce gas into the stator during the compression stage. This prevents vapor condensation inside the pump, dilutes and ejects corrosive gases and purges the gases and vapors. Therefore, the use of gas ballast reduces oil degradation and pump corrosion.

Vane pumps are available in Single stage and Dual stage. Performance difference lies in the vacuum range.

Single Stage Vane

Single Stage (VP1): VP1-10, VP1-20, VP1-25, VP1-40, VP1-63, VP1-100, VP1-200, VP1-300

Single Stage Vane pump is oil-sealed with pumping speed ranging from 6 CFM to 177 CFM. Compact and rugged designed. They feature advanced lubrication circuits with high reliability. This type of pump is commonly used in industrial application because of its high initial pump down and low cost. It is also used as backing pump for Roots Blower.
