Velp JPV Recirculating Water Vacuum Pump

VELP Scientifica has developed a recirculating water vacuum pump, JPV model, which assures a constant water recirculation (previously introduced in the tank of the pump). This allows a drastic decrease of water consumption.

Vacuum generation is necessary for a variety of applications in petrochemicals, refineries, process, chemical, plastics, pharmaceuticals, pulp & paper for distillation, drying, evaporation, degassing that frequently take place at less than atmospheric pressure.

Ideal for all those applications where non-pulsing suction is needed Typical examples may be rotary evaporators, vacuum filtrations, (SPE), etc.

Use of common water pumps is frequently prevented by a lack of adequate water mains pressure or by its high consumption

  • Circulator replaces expensive water consumption
  • Provides vacuum where no reliable water supply is available
  • Extremely quiet and vibration-free

Easy to Use

  • Inset handles to simplify lifting
  • Flow rate adjustable from 0 up to 22 litres per minute
  • Vacuum level adjustable from atmospheric to 0.04 bar
  • ABS structure
  • Stopcock for emptying the tank
