W250 Triplex Pump

Contact

The Weatherford W250 triplex power pumps are offered with fluid cylinders of nickel-aluminum bronze, forged carbon steel, or duplex stainless steel.

A variety of packing and valve arrangements are available to meet the requirements of any application. The critical components of the power end—crankshaft, connecting rods, crossheads, and bearings—are comparatively larger than industry-standard components, which enables them to withstand continuous-duty service and harsh operating conditions.

Standard Equipment

  • Cast aluminum-bronze, forged duplex stainless steel, or forged carbon steel fluid ends
  • Aluminum-bronze or duplex stainless steel stuffing boxes
  • Various valve designs offered per fluid end style
  • Tungsten carbide coated plungers over stainless steel base or solid ceramic plungers
  • Double extended crankshaft
  • Multiple plunger packing arrangements offered

Optional Accessories

  • Weatherford bolt-on gear reducers (ratios)

General Notes

  1. Capacities shown are based on 100 percent volumetric efficiency. Actual capacities are lower, based on discharge pressure and fluid compressibility.
  2. API-674 and NACE-compliant designs are available; consult Weatherford for details and exceptions to these standards.
  3. For operation below 200 RPM, an auxiliary lubrication system is required.
  4. Standard plunger sizes are shown, however other sizes are available upon request.
  5. Spherical valves must be installed when using 4.00 in. plungers.
