DPH pumps are hydraulically driven extra heavy duty submersible pumps. The design of the wet part of the pump is similar to the DP pumps but the powerful hydraulic piston motor offers the following specific advantages:

• The rotation speed of the motor is adjustable, which enables the pumps capacity and pressure to be adapted to suit changing job site requirements and circumstances.
• When the pump is mounted on the arm of an excavator, its motor can be directly connected to the hydraulic generator of the machine.
