Williams Vmac™ Series model D is an Electric Driven, Chemical Injection, positive displacement plunger pump utilizing double spring loaded lip seals and an integral worm gear drive. It is available in 2 different standard gear ratios and 3 plunger sizes with flow up to 45.4 gpd (171.7 lpd) and pressure up to 5,000 psi (344.7 bar). It is used for oil and gas production facilities, pipelines, process plants, and other applications where precise dosing is required.

  • Durable metallic, powder coated, sealed housing designed to withstand tough environments and longer life
  • Robust metallic, worm gear drive coupled with variable eccentric stoke adjustment mechanism yields a 10:1 turndown ratio with smoother flow
  • Precision stroke adjustment can be operated while the pump is running or stopped
  • All gear components move in an oil bath for long life
  • Steady State Accuracy ± 1% of full capacity over 10:1 turndown ratio
  • Proven Williams double sealing arrangement yields longer leak-free life when combined with ceramic plunger (standard offering)
  • 316SS Liquid end body for corrosion resistance
  • No packing to adjust
  • Suction and discharge check valves with composite seats for long life and positive sealing
