What kind of pump does a dump truck use?
For decades, the dump truck industry has been relegated to two sizes of dump pumps; a larger, higher flowing (up to 27GPM) C Series pump, and a smaller, lower flowing (up to 16GPM) G series pump. The smaller size of the G series pump is ideal for trucks with automatic transmissions.
What are the pressures on a Parker dump pump?
Parker’s dump pumps provide the most reliable, trouble free performance in the industry for dump truck and trailer applications. Operating pressures up to 138 bar (2,000 psi) and speeds up to 2,400 rpm. ???ACCE_Region_Product_List???
How big is a PTO pump dump truck?
2001 f 550 7.3. Pto pump dump. Has a sissor hoist for an 11 foot dump bed. Last week we scaled in at 4,000 in the bed pretty much equally distributed and the hoist would not raise the bed. It would dump 3500 lbs, but not 4.
How is a dump pump connected to a transmission?
All dump pumps are connected to a power take-off unit (PTO), which is mounted to the truck’s transmission. The PTO draws power from the transmission and allocates it to the dump pump. The truck’s transmission is nestled between the frame rails of the truck chassis.
A dump pump as used on a typical dump truck in N.A., is a combination of a hydraulic pump, a pressure relief valve and a directional control valve in one housing. The pump also has a pressure port that connects to the hydraulic cylinder and a larger port connected to the hydraulic reservoir.

Can a dump pump be left on too long?
This system does function effectively as long as the pump is not operated too long with the oil circulating within the pump. If the PTO is left engaged for an extended period of time, such as driving away from the site, the pump gears continue circulating approximately a cupful of oil.
What causes oil to come out of a dump pump?
When the directional valve is shifted to the raise position, the passage to recirculate oil is blocked, forcing the fluid out the pressure port to extend the cylinder. If the pressure reaches the set point of the relief valve, it opens returning the oil to the inlet side of the pump.
