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 22 kW MS6000 motor with sand shield, mechanical shaft seal, water-lubricated journal
bearings and a volume compensating diaphragm. The motor is a canned type submersible motor offering good
mechanical stability and high efficiency.
The motor is fitted with the Grundfos Tempcon sensor that, by use of powerline communication together with a
MP204 control panel, enables temperature monitoring.
The motor is for direct-on-line starting (DOL).
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. The suction
interconnector is designed to comply with NEMA standards for motor mounting/dimensions.
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.
The shaft seal faces are ceramic/carbon. The material combination provides good dry-running resistance. 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.
The motor is fitted with the Grundfos Tempcon temperature sensor device that includes a NTC-resistor which senses
the temperature.
The resistor is built-in close to the winding.
The temperature is converted into a high-frequency signal which is sent via the submersible drop cable and which
can be converted into a temperature reading by means of Grundfos MP204.
The MP204 is an electronic motor protection device that also monitors the supply network quality to protect the
submersible motor against supply network disturbances.
