4SR 1/50 S-PD - 3 HP three-phase submersible electric pump
Flow rate up to 30 l/min (1.8 m³/h). Head up to 350 m. 2.2 Kw (3 HP) motor.
The 4SR 1/50 S-PD electric pump by Pedrollo is suitable for use in the domestic, civil and agricultural sectors.
Pedrollo has created this pump with the aim of producing a product that is efficient in terms of operation and robust in terms of construction.
The 4SR 1/50 S-PD has a refined hydraulic design that guarantees exceptional performance and efficiency and a remarkable resistance to wear caused by the presence of sand in the water. Its construction allows the pumping of water with sand content up to 200 grams per cubic meter.
Equipped with an innovative patented inductor that guarantees a high priming capacity for operation in wells with the presence of gas or air mixed in the water.
It can be used for water distribution in conjunction with pressure tanks, for irrigation, for washing systems, for pressure boosting.
The 4SR 1/50 S-PD can be installed in all wells with a diameter of at least 4 inches, i.e. 100 millimeters. It can be lowered into a well up to 200 meters underground.
It has a flow rate that varies from 5 to 30 litres per minute with a head of 155 to 350 metres.
It must be powered by a three-phase voltage and has a horsepower of 3 HP.
The 4SR 1/50 S-PD has the body and pump shaft made of AISI 304 stainless steel and the impeller is made of noryl, these materials ensure that the pump is robust and resistant.
The 2 meter long power cable and the capacitor are supplied.
