Series LD3 AB three-piece all bronze booster pumps are used for domestic, potable water. LD3 pumps are oil-lubricated with a 1/4 HP, 1725 RPM, 115v, single-phase motor. Series LD3 pumps are reliable, in-line booster pumps intended to pump potable, domestic water from hot water heater tanks to areas such as bathrooms and kitchens or non-potable water through closed loop systems for heating and cooling and increased flow and head pressure applications. They feature a three-piece design, which includes a motor, bearing assembly, and volute. Since the bearings, shaft, and seal are all housed within the bearing assembly, Series LD3 pumps are easily serviceable in the field. Resilient motor mounting combined with spring-loaded couplers means the pump runs quietly. A tube of oil, flange gaskets, flanges, and mounting hardware are included.
