gear pumps work according to the displacement method

they contain of three parts

  • the pumps housing
  • two gearwheels, one of which is driven by the motor, while the other gearwheel is driven by the first one

gear pumps are very reliable and cost-effective pumps due to their simple and rugged construction

all the the benefits at a glance:

  • low shear effect
  • feasible high pressures
  • suitable for high viscosities
  • consistent flow of medium
  • very good suction capapbility in terms of self-priming suction

various applications:

  • fluids without particles with either low or high viscosity
  • lubricants
  • light and heavy oil (e.g.: emulsions, diesel, lubricating oil, thermal oil, hydraulic oil, vegetable oil)

parts coming in touch with the fluid:

In order to reach a high durability the housing and the cover are made from grey cast iron GG-25, the shaft the the gears are made from tempered stainless steel.
