Pumps with interior gears | IPZ

 

Our IPZ series internal gear pumps are exceptionally small and quiet and operate with low pulsation (<4%).

 

With their excellent suction capacity and large torque speed range, their function with precision making them ideal for pumping non-corrosive and non-abrasive fluids with a viscosity of 10-500 mm²/s.

The permissible temperature range is -30 to +70 °C (Viton +120 °C), filtration: max. 25 μm.

 

The Perbunan seals offer more durability in comparison to standard hydraulic fluids and lubricants. Other seals are also available upon request.

Oil with 46mm2/sec viscosity is recommended for the hydraulics. A high viscosity is suggested.

Request an oil recommendation!

 

The standard rotation is right-handed (clockwise shaft rotation viewed).

 

  • from 0.01 to 2.3 cm3/rotation
  • corresponds to 0.15 to 6.9 l/min ( at 1500/min i.e. 3000/min)
  • viscosity from 10-500 mm²/s (recommended: 46 mm²/s)
  • gear teeth size from 0.01 cm³ to 2.3 cm³/r
  • pressure range from 120 bar (depending on oil type)
  • torque speed range up to 8000 r/min
  • excellent suction capacity
  • long lifespan
  • low noise
  • low pulsation
  • filtration: max. 25 μm
  • high precision makes it suitable for dosing
  • available also with motor

 

Please provide pressure, torque speed, temperature, medium and operational cycle for inquiries and orders!
