Grundfos Presscontrol PM: Efficient Control for Domestic Electric Pumps

Grundfos Presscontrol PM devices are designed to automate the starting and stopping of electric pumps, ensuring a constant water supply in domestic applications. These electronic pressure switches offer protection against dry running and cycling, ensuring efficiency and reliability in the water system.

Available Models

• PM 1 : Offers basic flexibility, starting the pump when the pressure drops below 1.5 bar or 2.2 bar, depending on the configuration. It is ideal for applications where a simple start/stop function is required.

• PM 2 : Provides complete control with an adjustable start-up pressure between 1.5 and 5 bar, adapting to different installation needs. Includes an internal pressure tank and offers additional protections for the pump.

Main Features

• Dry Running Protection : Devices stop pump operation in the absence of water, preventing damage to the system.

• Automatic Operation : They manage the starting and stopping of the pump based on water demand, maintaining a constant pressure in the system.

• Versatile Installation : They can be installed vertically, horizontally or at an angle, adapting to the available spaces.

• Intuitive Interface : Equipped with LED indicators for power status, pump operation and alarms, make it easy to monitor the system.

  
  

Typical Applications

• Home Pressurization Systems : Ensure constant water pressure for single-family homes.

• Garden Irrigation : Automate water supply for residential irrigation systems.

• Water Supply from Tanks : They manage the supply of water from cisterns or collection tanks.

FAQ

• What is the main difference between PM 1 and PM 2?

  The PM 1 offers basic flexibility with a fixed start pressure (1.5 or 2.2 bar), while the PM 2 allows for start pressure adjustment between 1.5 and 5 bar, offering more complete control and adaptability to different needs.

  
  

• Can Presscontrol PMs be used with pumps from other manufacturers?

  Yes, Presscontrol PM devices are compatible with electric pumps from various manufacturers, as long as they comply with the specified electrical and pressure parameters.

• How are Presscontrol PM devices installed?

  Installation is simple and can be done in different positions (vertical, horizontal or corner). It is important to follow the manufacturer's instructions and, if necessary, consult a qualified professional.

  
  

• Do Presscontrol PM devices offer dry-running protection?

  Yes, both the PM 1 and PM 2 models have built-in dry-running protection, stopping the pump from operating in the absence of water to prevent damage.
