UV Series Condensate Return
UV Series units are uniquely designed for below-grade applications. Each pump consists of a vertical pump and motor unit and has either a flange-type float switch mechanism to control pumping from the water level in the receiver or a flange-type float-operated makeup valve to control pumping from the water level in the boiler. UV Series Condensate Return units are designed to collect condensate below floor level and quickly return it to the boiler feed unit using various pressures and flows. Pumping action is controlled by the water level inside the receiver and an integral and adjustable float device is used to turn the pump(s) on and off.
