DIRECT DRIVE ROTARY VANE PUMP
direct drive impeller pump
impeller pumps are known for their reliability and longevity.
The housing material can be selected from brass, stainless steel or engineering polymer, which can be used in the food and beverage industry. Vane pumps are the first choice for most OEM customers.
A built-in relief valve can be provided on request to limit pressure to protect the pump and hydraulic circuit.
A variety of elastomeric materials are available for a variety of fluids, from corrosive solvents to drinking water and food grade liquids.
direct-drive rotary-wheel pump is a positive displacement technology in which the flow rate is proportional to the speed. The combination of high-quality raw materials, relatively high flow and pressure performance at the same size, make it the first choice for many water-based applications.
stable performance, no pulsation transmission
high working pressure
- Paints and Inks
- water treatment
- Other Industries
Compared with the diaphragm pump,impeller pump features:
- low pulsation
- continuous flow
- longer life
- No check valve required
Compared with centrifugal pump,impeller pump features:
- high working pressure
- Good suction capacity
- low energy consumption

DIRECT DRIVE ROTARY VANE PUMP
VANE PUMPS ARE RENOWNED FOR THEIR RELIABILITY AND LONGEVITY.
Available with brass, stainless steel, or engineered polymers housing for use in the food and beverage industry, they are the preferred choice for most OEMs.
The built-in relief valve, available upon request, limits the pressure to protect the pump and the hydraulic circuit.
Multiple elastomer options are available for a broad range of fluids from aggressive solvents to potable water and food-grade liquids.
This option takes all the advantage of a direct drive rotary vane pump and eliminates the shaft seal by introducing a magnetic coupling.
Stable, pulsefree delivery
High pressure capability
High flow rate
Sealless pump - No dynamic seals, zero leakage
Higher system pressure capability
Well suited to pumping hazardous or hygeinic fluids
No pump or motor shaft wear
No misalignment between pump and motor shafts
Safer fluid containment
