L-Series Liquid Pumps - Pressures From 165 to 60,000 PSI

The L Series High Pressure Liquid Pumps are available as single acting with either a single or double air drive head and double acting with single air drive head.

  • L series air driven high pressure liquid pumps have stainless steel bodies and 17-4 plungers. All L pumps have UHMWPE (Ultra High Molecular Weight Polyethylene) seals and Viton2 O-rings (-VE).
  • Maximator L series pumps come standard with a bottom or side inlet. For side inlet, add – S to catalog number.
  • Maximum air drive pressure 145 psi.
  • Minimum air drive pressure 15 psi.
  • For air control option ... add – ACP to catalog number.
  • All L pumps come with an unregulated pilot port, 1/8" FNPT, in the top cap. This feature provides more accurate pressure control and is an ideal location for control instrumentation.
  • All L pumps are available with a double air drive head. This doubles the pressure ratio of the pump, allowing the use of a lower ratio base pump, to provide higher flow rates. It is also used to achieve a given outlet pressure with less air drive pressure. Add -2 to the catalog number.
