Piston pump; Type PPU / PHU
Piston Pump of the type PPU and PHU
The piston pumps PPU and PHU are each available with two different delivery ranges. They can either be flanged directly to the corresponding oil or grease containers 2.5 and 5.0 kg, or can be connected via a pipeline to a grease or oil container.
The pumping volume can be adjusted continuously by changing the pump stroke.
The pneumatic connection can be attached in two different ways: Either with a 3/2-way valve and one-sided (piston return through integrated spring) or double-sided via a 4/2-way valve for faster usage.
- When using grease, double-sided loading is recommended
