  • Adjustable pressure gear pump.
  • It works with specially designed external gears, ensuring greater efficiency and quiet operation.
  • It is a self-priming pump. That is to say, with the installation empty, the pump is able to aspirate the liquid causing a vacuum pressure in the suction pipe.
  • It integrates an adjustable pressure valve inside the gear casing. It allows the customer to regulate the operating pressure of the pump up to 8 bar.
  • Specially designed for small flow rates.
  • Suitable for transferring fuel oils. Specially designed to operate in parallel with burners.
  • Compact monoblock construction with a single motor-pump shaft.
  • Single-phase motor with thermoamperimetric protection.
  • Sealing solution with lip seal according to DIN 6370, in NBR.
