Series UP3/4 Gear Pumps for Water & Engine Oil

Water to 3.7 GPM, Oil to 1.5 GPM, Pressure to 29 PSI

DESCRIPTION

Model UP(3,4)/Oil, and UP(3,4)/P are self-priming, compact, powerful, 12 or 24 VDC electric gear pumps. UP3/Oil is constructed of helical bronze gears, nickel-plated brass body and stainless steel shaft. UP3/P has PTFE gears.

Use UP(3,4)/Oil for transfer, circulation or drainage of lubricating oils and viscous liquids. Use UP(3,4)-P for fresh and salt water as well as for diesel fuel.

The E Option for UP(3,4) is a built in pressure control whereby a factory programed pressure setting is maintained via a built-in microprocessor based variable pump speed control circuit that utilizes an internal pressure sensor for loop feedback. Main application is low cost pressure/flow control for small water and process systems.

The UP(3,4) measures a mere 5 3/8” in length and fits easily in the tightest of spaces.
