Agriculture and irrigation
Our high-efficiency pumping solutions work seamlessly with modern irrigation systems for agricultural and non-agricultural applications. We offer a full range of reliable pumps and systems designed for minimal maintenance with low operation costs and a long operation life.
Pumping solutions for all irrigation and agriculture needs
Energy is often one of the highest operating costs for many farms, greenhouses, and golf courses. Grundfos supplies high-efficiency agricultural and irrigation pumps that are built for reliable operation with minimal maintenance requirements. Our pumping expertise and commitment to innovation deliver advanced pump systems, and control solutions that simplify installation and operation while delivering the features and cost-saving benefits businesses are looking for.
Regardless of your water source, power supply, or water treatment needs, Grundfos has a solution for you. We supply pumps for groundwater and surface water intake, pivot and micro drip irrigation, frost protection, livestock watering, and fertigation and chemigation systems.
Use our water cycle animation and find which products match your project
Starting with the water network, Grundfos supplies cost effective, reliable and energy optimised pumping solutions for raw water intake; pumping, dosing and disinfection solutions for each stage of the water treatment cycle; and pumps and controls for the entire water distribution system, including main and local pumping stations.
For the wastewater network, Grundfos supplies dependable, energy efficient solutions for wastewater transport and flood control, ensuring that downtime is reduced, and risk minimisation is built into the system.
And at the wastewater treatment plant, Grundfos facilitates reliable operation and low total cost of ownership through a broad range of products and solutions for mechanical, biological and chemical treatment.
CUE Features & Benefits
Grundfos 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 can optimize the performance of your system to meet the exact needs of your application including constant pressure, proportional pressure, constant flow and more.
Download the brochure and learn more about the features and benefits of CUE.
A perfect match to reduce your total cost of ownership
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.
Finding your perfect match
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.
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
Designed for installations with one or two wastewater pumps, the Grundfos LC level controller is ideal for emptying and filling in wastewater network applications. Read our brochure to see how easy it is to set-up, configure and connect – giving you smart and intuitive level control.

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 fibers.
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 the pump 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.
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.
