Welling PSB-12(DC) AC Drain Pump Motor (DC12V 0.23A 1700r/min)

Designed to drain the condensate water that accumulates in the indoor unit of air conditioning systems quietly, quickly and safely, the Welling PSB-12(DC) Drain Pump Motor combines high performance with low energy consumption. Manufactured with the quality of Welling, one of the leading motor manufacturers in the industry, this pump is developed for full compatibility especially with inverter air conditioners and cassette type indoor units.

Uninterrupted Drain Performance with Low Current and High Speed

This drain motor operates on a low-voltage DC 12V supply, both saving energy and providing a safe working environment. Although it draws only 0.23A of current, its powerful internal design reaches a speed of 1700 revolutions per minute (1700r/min) and can pump the water accumulated in the condensate pan to vertical and horizontal lines without strain. The motor design with Class E insulation is extra resistant to heat and long operating cycles.

Installation and Replacement Note for HVAC Technicians

Technician Note: When the air conditioner indoor unit leaks water, overflows or "goes into a fault code", always check whether the drain pump is mechanically seized, as well as its coil resistance. When replacing the Welling PSB-12(DC), make sure the socket connection is fully seated and the water inlet-outlet hose clamps are tightened leak-free. Fixing the device to the body using the screw holes in the pump's lower mounting lugs will minimize vibration and therefore operating noise.
