Submersible Pump — Model Range

Choosing a PW Series Submersible Pump

Submersible pumps sit fully underwater, pushing water up the discharge pipe rather than drawing it through a suction line, so priming is not needed. The PW series is a compact, corrosion resistant range for clean water, with IP68 motors and built-in thermal overload protection. Typical jobs include garden and fish ponds, drainage, emptying tanks and confined-space pumping such as cleaning washing towers.

The PW_A series comes in 100, 250, 400 and 800 W outputs. The 100 W model has a 1 inch outlet, maximum head of 6.5 m and up to 80 L/min, while the 800 W model has a 2 inch outlet, 14 m head and up to 440 L/min. The PW_E series adds a 250 W model with a 1 1/2 inch outlet. All are offered for 50Hz and 60Hz supplies.

The letter codes after the model number identify the function. R models are rated for sea fish breeding and saltwater. F models have an automatic float ball level switch and C models have an electronic level regulator, both allowing the pump to start and stop with the water level for unattended use. D models are low-suction pumps that can drain down to 1 mm of residual water, useful for clearing floors and flat-bottomed tanks. Choose output by the flow and lift needed, then add the function your installation requires.
