Pressures from 165 to 101,000 PSI

L 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 pumps have stainless steel bodies and 17-4 plungers.
• All L pumps have UHMWPE (Ultra-High Molecular Weight Polyethylene) seals and Fluorocarbon (FKM)² O-Rings (VE), except as noted.
• L series pumps come standard with a bottom or side inlet. For side inlet, add -S to catalog number.
• Air drive pressure range is 15-145 psi unless limited by outlet pressure.
• Air drive inlet is 1/2" FNPT.
• 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 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.
