Udor Diaphragm Pumps and Kits
Udor is an Italian manufacturer of semi-hydraulic diaphragm pumps for agricultural, lawn care and pest control spraying. Udor pumps are known for smooth, steady pressure and long service life, and like all diaphragm pumps they're built to be rebuilt. QSpray stocks Udor pumps along with the diaphragm kits, valves and control units to keep them running. Shop all Udor diaphragm pumps and kits.

Control Units and Repair Kits
The control unit mounts on the pump and sets your spray pressure, sending extra flow back to the tank. Along with the series-specific units above, we carry the SB3 control unit and SB3 repair kit, the 6005.31LP regulator control unit, and control unit repair kits 6062.53, 6062.93 and 6062.A9.
Keep Your Udor Pump Healthy
Check the oil regularly. If it turns milky or gray, a diaphragm has failed and chemical is getting into the crankcase. Stop the pump and replace the diaphragms right away to avoid damaging the rest of the pump. Questions about which kit fits your pump? Call us at 602-371-1993.
