Grundfos Submersible groundwater pump SP 5A-33

Grundfos SP are submersible borehole pumps, designed for pumping groundwater. Grundfos SP are all stainless-steel pumps, and they are available in 3 material grades. The pumps are suitable for boreholes in sizes ranging from 4″ over 6″ and 8″ to 10″. The motor sizes for the pumps are available in 0.37-250 kW.

Submersible borehole pump, suitable for pumping clean water. Can be installed vertically or horizontally. All steel
components are made in stainless steel, EN 1.4301 (AISI 304), that ensures high corrosive resistance. This pump
carries drinking water approval.
Further product details
The pump is suitable for applications similar to the following:
– raw-water supply
– irrigation
– groundwater lowering
– pressure boosting
– fountain applications.
The Grundfos SP pump is renowned for its high efficiency and already complies with the requirements of the
Minimum Efficiency Index, and therefore Grundfos is amongst the best in class within submersible pumps.

Pump
All pump surfaces that are in contact with pumped liquids are made in stainless steel which makes them corrosionand wear-resistant.

The elastomer parts in the pump are made of NBR (Nitrile-Butadiene Rubber) and TPU (Thermoplastic
Poly-Urethane) which offers good wear resistance and long service intervals.
The suction interconnector is fitted with a strainer to prevent large particles from entering the pump. The suction
interconnector is designed to comply with NEMA standards for motor mounting/dimensions.
Motor
The stator is hermetically encapsulated in stainless steel and the windings are embedded in polymer compound. This
results in high mechanical stability, optimum cooling and reduces the risk of short circuits in the windings.
