The Competition
Competitive strippers use gear pumps for their hydraulics.
Gear pumps run at full power all the time. That means a pump that produces 9 gallons/min. at 3000 psi when running is always delivering 9 gallons/min. at 3000 psi.
To reduce speed, you must shear the oil flow (divert the unused oil back to the reservoir). This is done with servos/proportion valves. In order to get reasonable operating power and control, the speed must be slowed down.
The diverted oil contains wasted energy in the form of heat which must be evacuated and which raises the ambient temperature of the work environment.
Gear pump driven equipment operates in a herky-jerky fashion. When trying to move with precision, there is no initial response on the controls, and then suddenly the machine lurches forward. This erratic cadence puts walls and molding at risk.
SURVEYS SHOW THAT HYDRAULIC ENGINEERS OVERWHELMINGLY PREFER HYDROSTATIC PUMPS OVER GEAR PUMPS FOR THIS TYPE OF EQUIPMENT!
