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. Standard plunger sizes are shown, however, other sizes are available upon request.
  4. A 4-GPM filtered power end lube system is required. The internal plumbing is included with the pump. Weatherford offers two optional systems, external electric driven and internal change driven.
