CDR800 Mud pump
CDR800 Mud pump
CDR series pump cylinder, crankshaft, herringbone gear and other important parts are made of high-quality alloy steel, the frame is welded with plates, high strength, good rigidity, light weight.
Product Introduction
- CDR series mud pump has advanced structure, compact, small volume, good performance, and is suitable for drilling technology requirements of high pump pressure and large displacement in oil field.
- CDR series mud pump has a long stroke, which can be used at a low stroke number to effectively improve the water-loading performance of the mud pump and prolong the life of vulnerable parts at the hydraulic end.Advanced structure of suction air bag, reliable use, mud pump can achieve the best suction effect.
- CDR series pump cylinder, crankshaft, herringbone gear and other important parts are made of high-quality alloy steel, the frame is welded with plates, high strength, good rigidity, light weight.
- CDR series mud pump has high interchangeability. All vulnerable parts at the hydraulic end are interchangeable with parts of the same specification and model that meet the requirements of API specification.
