Wonchang B Series vacuum boosters are positive. Displacement, roots-type blowers intended for use in Conjunction with a mechanical backing pump.
The B booster pumps have a simple weighted By pass design that allows start-up from atmosphere.
The design has the following advantages:
Pump-down times cut by up to 50%
Reduced capital and operating costs
NO pressure sensors, special drives or leaking seals.
Can operate continuously at all pressures when used with a backing pump.
The bypass design allows the booster to be started at the same time as the backing pump (at atmospheric pressure) as it prevents motor overload. The B booster pump therefore assists the pumping process from the start of pump-down.
Magnetic Drive Coupling provides positive seal from shaft leakage
Vertical flow self draining in all models
Weighted bypass ensures simple, trouble-free cut-in
Available for applications where oxygen or other reactive gases are present
Quiet, vibration free operation
Simple installation, can be mounted directly on backing pump.
