Improved discharge
Easier and safer attachment to the riser pipe
Cable guard attachment
Improved screw-on attachment of the cable guard
Built-in non-return valve
All SP pumps are delivered with a non-return valve to minimise the risk of water hammering damage
Corrosion resistant
AISI 304 stainless steel inside and out makes the SP very resistant to corrosion and extra high-grade steel versions for aggressive liquids are also available
Wear resistance
Less abrasive wear: Octagonal bearings and sand flush channels remove particles with the pumped water. Sand resistance is further increased by using the bearing that provides a longer lifetime in sandy underground environments
Optimised hydraulics
For better performance and fewer breakdowns
FKM rubber parts
This option makes the SP suitable for water slightly contaminated with, for example, oil
Stop ring
Protect the pump in case of up thrust
Failure rate close to zero
Durable and well-protected: Statistics compiled since 1967 show that SP pumps have a warranty return rate close to zero
Customised solution
Contact your Grundfos distributor if you require a SP system tailored to your specific application
Exchangeable shaft seal
The standard mechanical shaft seal used in the MS/MMS motors is very easy to service and replace. For applications that involve sand or abrasives, a SiC/SiC sand-resistant shaft seal is also available
Tempcon sensor (MS)
MS motors are available with a built-in Tempcon or Pt 100/1000 temperature sensor, eliminating the need for extra cables or sensors
Corrosion resistant
The MS/MMS motors are available in stainless steel to match the corrosion resistance of the SP pump units. Extra high-grade steel versions for aggressive liquids also available
Rewindable motor (MMS)
In MMS motors the stator can be rewound locally, ensuring minimal cost and downtime
High thrust capacity
Michell-type thrust bearings with high thrust capacity. Quickly builds up a water film during start-up to ensure high thrust capacity
Motor protection and monitoring
Optimise reliability and monitor performance with electronic motor protection (MP 204) or a Variable Frequency Converter (CUE) and a remote monitoring system (Grundfos Remote Management)
Warm water versions
Available for temperatures up to 60°C for MS and 50°C for MMS motor series
SPE pumps are a part of the broader SP range and are frequency-regulated submersible pumps designed for groundwater. They are known for their high efficiency and resistance to abrasive materials. Like the SP pumps, SPE pumps are made entirely of stainless steel, and they come in three material grades. The 6" motor (4 to 45 kW) is a permanent magnet type that offers high energy efficiency but requires a frequency drive for operation.
Durable stainless steel construction ensures long-term durability and resistance to corrosion and abrasion.
Available in 6", 8", and 10" sizes.
The frequency drive allows for variable speed control, optimising performance and energy efficiency.
Grundfos submersible centrifugal groundwater pumps are designed to extract water from underground sources and transport it to the surface. These pumps are submerged in water and utilise a motor and impeller to create a pressure difference that forces the water upwards through a riser pipe or hose. They are constructed from corrosion-resistant stainless steel and are equipped with a hermetically sealed submersible motor.
