Grundfos 4” SPE pumps are submersible well pumps for use in 4-inch and larger wells. SPE pumps are made of corrosion resistant stainless steel and are suitable for use in Environmental applications. 4” SPE pumps are available with nominal flows from 5 GPM to 25GPM.


4” SPE

Specially designed for environmental protection, the submersible SP Environmental pumps (SPE) are resistant to chemical and oily solutions in water. The pumps are built for the withdrawal of contaminated/polluted groundwater from places such as

  • dumps
  • chemical depots
  • industrial sites
  • garages and filling stations.

As they are made of inert materials, the SP Environmental pumps are also suitable for the following applications:

  • sampling and monitoring
  • pumping in water treatment systems
  • pumping of industrial process water.

Features and Benefits

Bearings with sand channels
All bearings are lubricated by the pumped liquid.

Inlet strainer
The inlet strainer prevents entry of particles over a certain size.

Priming disc
The Grundfos SPE pumps are fitted with a priming disc. That prevents dry running as the priming disc ensures lubrication of pump bearings during operation.

Protection against upthrust
The stop ring prevents damage to the pump during transportation and in case of up-thrust in connection with start-up.

The modular pump and motor design facilitates installation and service.

Protection against upthrust
Grundfos pumps and motors are protected against upthrust as standard, the protection consists of either a built-in stop ring or a hydraulic balancing device.

Shaft seal
The ceramic/tungsten-carbide shaft seal provides optimum sealing and wear resistance.
