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.
The Broncos hydrostatic pumps use only the oil flow and pressure that is required to do the work.
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 Bronco’s hydraulic circuit is a closed loop circuit which means that the only oil that is returned to the oil reservoir is the blow-by from the pistons. There are no servos or proportion valves in the Bronco’s system. The pumps are operated mechanically.
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.
Hydrostatic pumps run at much lower pressures which is a better use of energy and safer to operate. And the Bronco’s hydrostatic pumps have a positive auto-neutral return system that immediately returns the controls to neutral when released. The neutral return is quick and accurate with no coasting. The machine comes to a quick, positive stop every time.
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.
The Bronco’s controls in tight areas is very precise. The controls are responsive even when moving inch by inch such as when boarding an elevator.
