• WS-1000-SH

    The Mission™ WS-1000-SH is the latest addition to our well service pumps product line. This pump has the capability of being mounted in back-to-back arrangements in order to handle a variety of well service application. With 100,000-lb rod load and weighing 7,250 lb, this pump offers great horsepower in a very compact design.

     

    Description

    We are proud to introduce the WS-1000-SH quintuplex well service pump for cementing, coiled tubing pumping, snubbing, and acidizing services. This 1,000-hp pump maintains the same compact footprint of competing models, allowing for dual back-to-back setup. It's forward-thinking design features many enhancements over competitors' offerings proven to increase durability and facilitate ease of maintenance.

    Design enhancements:

    • Improved ingress protection - wiper seal and splash guard design improved to keep process fluid out of power end
    • Redesigned power frame - removal of multiple leak paths preventing environmental contamination
    • Enhanced gear set - improved design for reduced wear and long trouble-free service
    • Precise alignment made easy - symmetrical dowel pins ensure precise alignment between the fluid and power sections of the pump without the need to measure or shim anything
    • Robust one-piece fluid cylinder with integral inserts - ridged design improves strength and life while reducing chance of fluid leakage
    • Reinforced rib supports - increased strength at high-load areas for long life and reliable operation
    • Intelligent gland design - reduced component stress by 20,000 pounds per square inch, multiplying component life while increasing ease of maintenance
    • Longer lasting, safer wrist pin - addition of an anti-rotation pin to lock wrist pin orientation ensures high-stress areas remain out of the load path.
