Udor was founded in 1966 and continue to be a leader in the development and manufacture of diaphragm pumps and plunger pumps for pumping water. The RC122 pump comes with premium quality bearings for heavy duty applications and a more compact pump flange to facilitate gearbox assembly on the pump. It features a larger capacity oil bath crank case for increased lubrication. There is a double sealing 0-ring gasket between pump and motor bell housings to avoid oil leakage at high temperatures. The noise level has been reduced compared to its previous model. To Suit pumps : B / BK / MS / MWT / C / CS / CWT / CK / CX / CH
