GDF 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. 

GDF-D Geological Drilling Mud Pump
Main application: seal element which can heat proof under 80℃, thus make it suitable for below material: mud, fresh water, sea water, oil, mixer with polymer, polymer fluid, water with foaming agent, etc.
Hydraulic source machine: GDF-D high pressure mud pump can adopt the hydraulic power with other machinery such as hydraulic exploration rig, petroleum exploration rigs, car rigs, hydrology rig, geothermal resource rig.
GDF-M Coal Mine Slurry Pump
Main application: Coal mine gas extraction drilling, coal geological exploration, hydraulic shoring, underground drainage exploration, coal seam detection and hydraulic fracturing antireflection, coal seam grouting waterproof and other areas.
Hydraulic source machine: GDF-M high pressure coal mine slurry pump can adopt the hydraulic power with other machinery such as all-hydraulic tunnel drilling rig, horizontal directional drilling, full hydraulic CBM drilling rig etc. 
GDF-Y Oilfield Slurry Pump
Main application: Oilfield pressurized water injection, oilfield fracturing stimulation, and polymer injection, profile, plugging etc. process of the oilfield.

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.
