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 Bypass design that allows start-up from the atmosphere. The design has the following advantages :

ㆍPump-down times cut by up to 50%

ㆍReduced capital and operating costs

ㆍNO pressure sensors, special drives or leaking seals.

ㆍCan 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.

Features

ㆍMagnetic Drive Coupling provides a positive seal from shaft leakage

ㆍAvailable for applications where oxygen or other reactive gases are present

ㆍSimple installation can be mounted directly on the backing pump.

ㆍIntegral oil cooler on largest models for tough applications

ㆍVertical flow self-draining in all models

ㆍweighted bypass ensures simple, trouble-free cut-in

ㆍQuiet, vibration-free operation
