GDD mud pumps use hydraulic power to convert hydraulic energy into the power that can convey high pressure mud. It’s self-suction plunger pump. The parts without rotation make piston linear motion.

Main application: Trenchless drilling field
Hydraulic source machine: Trenchless directional drilling, TBM machine, tube push bench, rotary drilling rig, wagon drilling etc.

1. High reliability: no rotating parts, less moving parts, longer free maintenance time, high abrasive resistance and self-lubricating ability, which decrease the operating cost. When the hydraulic power less than max. rated power, the pump will decrease the output power automatically thus make the pump safe.
2. High integration: small volume, light weight, easy to transport and assemble, easy to get power supply.
