Product No.: On request

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 4 kW MS4000 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. Suitable for temperatures up to 40 °C.

The motor is not fitted with a temperature sensor. If temperature monitoring is desired, a Pt1000 sensor
can be fitted.
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.
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 corrosion- and wear-resistant. The corrosion diagram below shows the capabilities of the pump
and motor in relation to the temperature in Celsius (y-axis) and the concentration of chloride in ppm
(x-axis).

 The elastomer parts in the pump offer good wear resistance and long service intervals. The bearings are made of
LSR (Liquid Silicone Rubber), sealing rings are made of TPU (Thermoplastic Poly-Urethane) and the non-return
valve is made of NBR (Nitrile-Butadiene Rubber). The special elastomer material of the bearings offers increased
resistance to sand and other abrasive particles (from 50 to 150 mg/l).

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.

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.
The shaft seal is a tungsten carbide/ceramic replaceable mechanical shaft seal. The material
combination provides optimum sealing, resistance and long life. 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 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.
