6SR44/20 - PSR - 30 HP three-phase submersible electric pump
Flow rate up to 1000 l/min (60 m³/h). Head up to 248 m. 22 Kw (30 HP) motor.
The 6SR44/20 - PSR electric pump by Pedrollo is suitable for use in the civil and agricultural sectors, in particular for diversified applications such as industrial, municipal and agricultural water needs, for the distribution of water in conjunction with pressure tanks, for irrigation, for pressure boosting and for fire-fighting systems.
The special feature of this pump is the construction of the impellers and diffusers made in such a way as to resist abrasion caused by sand. The pump allows the pumping of water with sand content up to 100 grams per cubic meter.
The 6SR44/20 - PSR can be housed in wells with diameters greater than 6 inches.
It is equipped with a rewindable oil-bath PSR motor which allows it to be installed up to 150 metres underground.
The flow rate varies from 200 to 800 litres per minute with a head from 39 to 248 metres.
The 6SR44/20 - PSR must be powered by a three-phase voltage, has a horsepower of 30 HP and the temperature of the liquid to be pumped goes up to +35 degrees centigrade.
The pump is made of a mix of cast iron, AISI 304 stainless steel and noryl. Pedrollo has used this mix of materials to create a robust product that resists work and wear.
The 4-meter long power cable is supplied.
