Introducing the first bearing-less rotary piston design
for pumps, compressors, W-H-motors with new work processes.
View in the stationary system and............................................View in the co-rotating system
(The cylinders are half cut off)
Clear water hydraulic at 1000 psi
First sea water hydraulic motor and first high pressure water pump
with the bearing-less and oil-free Wolfhart Principle
(6ccm, 5 GPM at 1000 psi and 3750 rpm (max 5000 rpm)
| 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 |
| Extended range of speed |
| Adjustable volume (optional) |
The second generation has a ceramic rotor for a long service live of a clean water hydraulic motor.
(6cc,
1000psi, max 5000rpm)
