(Please note, the pump can be fully submersed, however will operate in partial immersion.) The shaft is made from 201 stainless steel, and is complete with a ceramic graphite mechanical seal. The SPP2-4 is only available as a manual model. It has a 6m head, 70 litre/min flow rate and allows a free passage of 3mm. The outlet is 25mm. Whether the SPP2-4 pumps are being used in domestic or industrial applications, they are excellent value for money and superb quality. The pumps are ideal for dealing with small floods. It is not recommended to use SPP2-4 pumps in water features or ponds. To use the pump, simply place the pump in the deepest section of the water, turn the plug on, the pump will manually run, once all the water is pumped, turn the pump off and youre all done! The pump can be used in waters between 5°C and 40°C with a maximum submersion depth of 5m.
