The genuine Udor 6005.31/LP control unit for Udor diaphragm pumps. It combines an adjustable pressure regulator with a manual dump lever, a 1/4" gauge port and a 3/4" hose barb bypass back to the tank. "LP" is Udor's low-pressure version, rated to 350 PSI, which makes it a good match for pest control, lawn and landscape spraying at typical working pressures.

Check your pump's port thread before ordering. BSP and NPT threads look similar but don't seal together. Call us at 602-371-1993 to order a different version.
How do I start the pump with it?
Move the dump lever to the bypass position before starting so the pump starts without pressure. Once the pump is primed and running smoothly, close the dump and set your spraying pressure with the regulator knob.
Can it be rebuilt?
Yes. Use the Udor 6062.93 regulator repair kit to rebuild it when the pressure drifts or the regulator leaks.
Will it fit my pump?
It's used on the Gamma-62 and other Udor Zeta and Gamma series pumps. Udor makes many control units, so call us with your pump model to confirm before ordering.
