The simplest but most powerful piston actuating mechanism ever created.
Introducing the first bearing-less rotary piston design
for pumps, compressors, W-H-motors with new work processes.
The cylinders are half cut off.............................................View in the co-rotating system
Clear water hydraulic at 1000psi Video
First real clear water hydraulic motor and first high pressure water pump
with the bearing-less and oil-free Wolfhart Principle
6 GPM at 1000psi and 3600rpm (max 5000rpm, 2000psi)
| No bearings any more for the piston forces |
| Greatly reduced friction and wear even at high pressure and high volumes |
| Total oil-free operation - including the piston actuating mechanism |
| High efficiency |
| A one stroke working process only |
| A six cylinder axial rotary piston design |
| No inertia forces – only balanced rotating parts |
| The water has never to stop and reverse the flow direction as in a normal piston pumps |
| Completely hydraulic balance of all sliding parts |
| Anti blocking device |
| Anti seizing device for the pistons |
| Dry running |
| Self priming |
| Long lasting |
| No valves |
| Typical pump application for this model: 6 GPM at 1000psi and 3600rpm (max 5000rpm, 2000psi) |
| Adjustable volume (optional) |
