Description
RIGRS triplex piston api workover pump are designing for well servicing and fluid transfer operations where robust pressure performance and maintainability are requiring. We support configuration by target pressure, flow rate and fluid type, and can supply spare parts such as pistons, valves and packing. Share your operating requirements and we will recommend a suitable configuration with datasheet, lead time and pricing.
Widely used in all types of well maintenance and drilling shallow wells, with compact structure and light weight.
API Workover pump Technical description:
- Cross head. It is integrally cast with ductile iron and has good wear resistance.
- Lubrication system. The api workover pump adopts both forced lubrication and splash lubrication. It has a built-in gear oil pump.
- Gear pair. Integral herringbone gear transmission, high transmission torque, stable operation.
- Frame. It is welding from steel plates and annealing after welding. Necessary oil pools and passages are provided in the frame.
- Gear shaft. It is an alloy steel forging with herringbone teeth machined on the shaft. Both ends of the shaft can be equipping with a transmission device.
- Hydraulic cylinder. It is made of alloy steel forging, with I-type structure.
- Valve assembly. Configure API-7K standard valve.
- Crankshaft. Fully balanced forged and welded crankshaft, with light weight and stable operation. Both ends of the crankshaft are equipping with double row centripetal spherical roller bearings.
