U.L. listed pumps are manufactured for the petrochemical, chemical, and petroleum industries to meet safety requirements established by Underwriters Laboratory Code 79.

Pumps include Aluminum wetted components with durable Hytrel^® and PTFE elastomers, approved by U.L. to transfer volatile fluids.

Pumps are available in 3/4" (NDP-20) and 1" (NDP-25) port sizes, with flow ranges from 1-46 gallons per minute. U.L. Code 79 limits pump discharge pressures to no more than 50 PSI and pumping temperatures must adhere to the range of –20°F to 125°F.
