90% energy efficiency with our new permanent magnet motors
Grundfos supplies the SPE system with a permanent magnet submersible motor and tailored CUE variable speed drive. A Grundfos PM motor ensures 90 % energy efficiency due to close-to-zero rotor losses. The CUE continuously adjusts the speed of the pump to any pumping need. All together The SPE system has proven reliability and longer lifetime keeping total life cycle costs down.
See how years of experience with permanent magnet motors and profound application knowledge have resulted in an allstainless-steel pump with a number of built-in features.
CUE frequency drives: Features and benefits
Grundfos’ range of CUE frequency drives are highly versatile and can be used for easy, efficient operation in all application areas. By connecting a CUE with a Grundfos SP submersible pump, you’ll bring advantages to yourself as well as your customers.
Download the brochure and learn more about the features and benefits of CUE.
One of the simplest ways to reduce the cost of ownership is to pair your Grundfos submersible pump with a Grundfos submersible motor. This will ensure the longest possible product lifetime and highest efficiency and eliminate problems caused by incompatibility.

The first step towards the ultimate efficiency and reliability is finding the perfect motor match for your pump. To get an overview of available Grundfos submersible motors, download the flyer.
Predict, prevent and protect
Grundfos Connect enables you to monitor the condition of your pumps and pumping stations anytime, anywhere. Offering automatic notifications and personalised reporting, Grundfos Connect can help you predict issues, prevent costly downtime and protect your assets. If you’re looking to go about your business with complete peace of mind, Grundfos Connect is the ideal companion.
Time for replacement – assess your pump before you start
Whether a submersible pump is 100, 200 or 500 feet underground, drawing it or inspection can be a costly affair. But by using our designated free tool, you can measure the efficiency of a submersible pump while it is still in the borehole. Low pump efficiency may mean it’s worth drawing, cleaning or replacing. Our SQ and SQE pumps are great replacement pumps when the time comes.
Smart level control for emptying and filling applications
The Grundfos range of LC level controllers are designed to prolong the life of your submersible pump by preventing dry running. The user-friendly interface simplifies daily monitoring, saving you time and effort.

We have gathered frequently asked questions and their answers in one place. See the most frequently asked questions below or go to the Grundfos FAQ for a complete list of answers to your questions about our products.
What types of media can I pump with a submersible pump?
Pure, low-viscosity, non-explosive media without solid matter or long fibrers.
If a liquid with a density differing from that of water is to be pumped, the motor power required due to the change in hydraulic power should be taken into account.
When pumping fluids more aggressive than drinking water, the special material construction pump versions such SP N, SP R and SPNE should be used.
Is it possible for submersible motor pumps to run dry?
Dry running of Wastewater Pumps can damage the mechanical seal and the motor. For this reason, the float switches should be arranged so that the fill level in the shaft does not fall below the minimum level required to operate the pump. (See also ‘What minimum fill level is required to properly operate the pump?’). The actual conditions prevailing in the application in question must therefore always be reconciled with the information provided in the operating instructions or the datasheet before initial start-up of the pump.
On submersible well pumps, it is possible for a submersible pump to run dry. This caused by over pumping the well where the depth to water level drops while the pump is running. Until the water level in the well reaches down to the pump intake screen. Often submersible pumps pump more water then recovers into the well. Lowering the pump further down the well is the most common solution. Adjusting tank size and demand cycles also helps.
How do I set the motor protection on a submersible pump?
Setting the motor protection on a submersible pump
The overcurrent release integrated into the motor-protection switch must trip on cold start in less than 10 seconds at five times the maximum motor current stamped on the rating plate.
In order to provide the best possible protection to the submersible motor, the motor-protective switch should be set in accordance with the following guidelines:
1. Set overcurrent release to the stamped maximum motor current.
2. Let the pump run for half an hour at normal power.
3. Set the overcurrent release successively lower until the trip point is reached.
4. After that, set the overcurrent release 5% above this trip point.
Caution
If the tripping characteristic of the motor-protection switch does not fulfil these requirements, the motor warranty is void. The maximum adjustment value of the overcurrent release must not exceed the maximum motor current stamped on the rating plate. For motors wound for star-delta start-up, proceed as follows when setting the motor-protection switch, but note that the protective switch setting must not exceed a maximum value of:
Protective switch setting = stamped max. current x 0.58.
The maximum permissible start-up time for star-delta starters or for motor switches with autotransformers is 2 seconds.
Grundfos offers different devices for motor protection like the MP204 module, for further information, refer to CAPS.
Can the pump be operated using a frequency converter?
Grundfos offers numerous speed-controlled pumps that are referred to as ‘E-pumps’ and which come equipped with Grundfos MGE motors with an integrated frequency converter. The manufacturing costs and material inputs are lower compared to pump solutions with external frequency converters. In addition, technical issues that may arise in connection with external frequency converters are avoided.
Finally, MGE motors have numerous additional features and advantages. In the event that no E-pump is available for a specific application, it is generally possible to operate the three-phase industrial motors offered by Grundfos via an external frequency converter. The technical information set out in the operating instructions and datasheet should be referred to in each individual case.
