China Vacuum Assist Pump Manufacturers Suppliers Factory

InPower vacuum assist pump uses a pair of 8-shaped rotors to rotate in opposite directions at a constant speed in the pump casing, generating suction and exhaust gases. Roots vacuum pump cannot be used alone, only the front stage pump in series can be used.

It is recommended to choose the inPower V series single stage rotary vane pump, D series double stage rotary vane pump, and LGB series oil-free screw pump as the front stage pump.

Characteristic：

1. Imported oil seals and bearings are used, with a runout of ≤ 0.02mm at the shaft seal to prevent oil leakage.

2. The pump body design includes an overflow valve, which has automatic overload prevention function.

3. The pump rotor support adopts a reliable clearance elimination structure and high-precision helical gears, which can operate for a long time under high pressure difference.

4. The annual sales volume reaches 10000 units, and it operates stably.

5. We can provide voltage and frequency products from different countries/regions around the world.
