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.
The pump is fitted with a 170 kW MMS10000 motor with sand shield, water-lubricated journal bearings and a volume
compensating diaphragm.
The rewindable motor contruction allows complete access to the windings for easy rewinding.
The stator windings are PE/PA insulated made for continous operations (S1).
Suitable for temperatures up to 50 °C.
The motor is fitted with a mechanical shaft seal.
The motor is not fitted with a temperature sensor. If temperature monitoring is desired, a Pt100 or Pt1000 sensor can
be fitted.
The motor is for star-delta starting (Y/D).
Further product details
The pump is suitable for applications similar to the following:
– raw-water supply
– irrigation
– groundwater lowering
– pressure boosting
– fountain applications.
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) which ensures good wear resistance
and long service intervals.
In case the pump is used for pumping water with high content of hydrocarbons or solvents, Grundfos offers FKM
rubber parts (Fluorocarbon) which are oil and temperature-resistant up to 90 °C.
The pump is built with octagonal bearings with sand flush channels that minimise wear. As wear of the pump is
inevitable, the pump design allows for easy replacement of all internal wear parts (bearings, impeller, wear rings and
seal rings) to maintain high performance and a long lifetime.
The suction interconnector is fitted with a strainer to prevent large particles from entering the pump.
Motor
The winding wire is made from pure electrolytic cobber insulated by extruded two layers of PE/PA with high dielectric
strength properties allowing direct contact between the motor fluid and winding wire.
This ensures the best possible cooling of the winding wire.
The PA layer ensures high mechanical wear properties of the winding wire.
The shaft seal faces are SiC/SiC.
The material combination gives good performance when abrasive particles (sand) is present.
Together with the shaft seal housing, the sand shield forms a labyrinth seal, which during normal operating conditions
prevents penetration of sand particles into the shaft seal.
This shaft seal is drinking water approved.
The motor can be fitted with a Pt100 or Pt1000 sensor that together with a control unit ensures that the maximum
operating temperature conditions are not exceeded.
