Detial Image
The new EIPH series has been developed especially for the rigorous demands of industrial hydraulics. The pumps in this series feature particularly low-noise operation, excellent efficiencies and a long service life. They can of course easily be combined to create multiple pumps with separate or common intakes.
The EIPH is a logical development of the gap-compensated Eckerle internal gear pumps that have been tried and tested in the industry for over 40 years.
Example applications:
Press technology | Marine engineering | Paper industry | Conveyor and lifting technology | Plastic and rubber injection moulding technology | Energy-efficient speed-controllable servo drives | Power plant technology | Wind power plants | Brake ventilator (for container gantries, cranes, lifts)
Application Equipment
ECKERLE EIPH series
Features of ECKERLE series gear pumps:
1. With radial and axial pressure compensation design, high efficiency.
2. The suction hole and pressure hole are 90°.
3. It is suitable for high-pressure hydraulic machinery such as injection molding machine, molding machine, servo energy-saving system. 4. Low pulsation and stable pressure to ensure stable mechanical operation and long service life.
