ZJ / ZJB Series Roots Booster Pump

ZJ / ZJB Series Roots Booster Pump

ZJ series mechanical booster pump, also known as Roots vacuum pump, is a positive displacement vacuum pump.

ZJ series Roots vacuum pumps are all made of horizontal structure. The medium and small pumps are directly connected with the motor by couplings, and the big pumps are driven by V-belts.

ZJB series Roots vacuum pump with overflow valve is a derivative product of ZJ type Roots vacuum pump. The pumping principle is the same as that of ZJ type pump. It rotates to produce suction and exhaust.
