The pump is driven by a 1-phase permanent magnet motor. The motor is characterised by high efficiency over a wide power range. To avoid pressure surges and high starting current, the pump is equipped with a soft start (max. 2 sec.). The pump is equipped with two eyelets for fastening the (stainless steel) rope safety device. Pumps of the SQ/E series are delivered from the factory with a replaceable motor cable.

Notes:
The submersible pump may be used to pump pure, low-viscosity, non-explosive media without solid or long-fibre components. If a liquid with a density different from water is to be pumped, the motor power required in this case must be taken into account because of the change in hydraulic power. When pumping liquids with an aggressiveness greater than that of drinking water, special designs must be used. Please contact us in this case. The maximum sand content of the water must not exceed 50 g/m³. A higher sand content reduces the service life and increases the risk of the pump blocking.
