UHP Control Unit

The Udor UHP is a high-pressure adjustable control unit (regulator) designed for large-volume, high-pressure diaphragm spray pump systems. Manufactured by Udor S.p.A. in Italy, the UHP sits at the top of Udor’s control unit range, handling the output of their largest 3- and 4-cylinder diaphragm pumps. It provides precise pressure regulation from zero up to 50 bar with a manual dump valve for safe start/stop operation, two independently controlled discharge ports, and a bypass return to tank.

Applications

• Large-scale agricultural spraying — orchards, vineyards, broadacre crops
• Horticultural spraying — nurseries, greenhouses
• Commercial pest and disease control
• High-volume turf and sports field management
• Any application requiring high flow at high pressure through diaphragm pumps
