W200 Triplex Pump

Contact

The Weatherford W200 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.

General Notes

  1. Capacities shown are based on 100% volumetric efficiency. Actual capacities are lower, based on discharge pressure and fluid compressibility.
  2. Operating power required by the pump is calculated by the formula: HP = (psi × gal/min) / 1,543, where psi is the actual operating pressure in psi units, and gal/min is the actual pumping capacity.
  3. API-674 and NACE-compliant designs are available upon request. Contact a Weatherford representative for specific details and exceptions to these standards.
  4. Standard plunger sizes are shown, however, other sizes are available upon request. Contact a Weatherford representative for performance and pressure ratings.
  5. Contact a Weatherford representative for assistance with pump selection on applications where actual operating inlet pressures are greater than 10% of the rated discharge pressure of the selected pump model.
  6. For operation below 100 rpm, an auxiliary power end lubrication system is required.
  7. Spherical valves are required for plungers above 3.75 in.
