Multistage Chemical Dry Vacuum Pump

Multistage Chemical Dry Vacuum Pump

HHV Pumps with seven years of experience in designing rotary vane and roots boosters pumps, brings in the latest chemical dry vacuum pump.

The design concept of the pump is based on oil-free, non-contacting, four stage hook and claw mechanism. It provides consistent vacuum at high efficiencies, lowest cost of ownership with adequate safety and performance standards.

The new pump is of 300m3/h capacity with an ultimate vacuum of less than 1 mbar.

Features

  • Four stage design with roots and claw combination
  • Vertical mount design to overcome by-product build up
  • Direct drive vertical motor
  • Water cooling in all stages and head plates
