Grundfos Motor Protection and Control

Grundfos SA-SPM Control Boxes

SA-SPM control boxes are used as starting units for single-phase, 3-wire motors, types MS 402B and MS 4000. A control box is required when purchasing a single-phase SP pump.

  • SA-SPM 2 is used for single-phase MS 402B motors with a power input lower than or equal to 0.75 kW
  • SA-SPM 3 is used for single-phase MS 402B and MS 4000 motors with a power input higher than or equal to 1.1 kW. The SA-SPM 3 incorporates a motor-protective circuit breaker and thus protects the motor against over load.

Grundfos Pressure Manager

The Grundfos PM 1 and PM 2 Pressure Managers are designed for automatic start/stop control of Grundfos pumps and other water supply pumps.

The PM 1 and PM 2 have a user-friendly interface with LED indicators showing:

  • power on
  • pump running
  • alarm indication
  • pressure indication (PM 2)

The PM 1 and PM 2 can be freely positioned in the installation- vertically, horizontally, or at an angle. This makes it easier to install the units in confined spaces and in extensive existing pipework. Due to robust electronics, the PM 1 and PM 2 can be powered by a generator or other alternative power supplies.

Both pressure managers incorporate a number of functions which protect both the pump and the installation.

Protective features:

  • dry-running protection
  • cycling alarm
  • maximum continuous operating time (30 minutes)(PM 2)

The PM 2 has an auto-reset function which can be used to automatically restart the pump.

Grundfos MP204 Motor Protection

A simple yet reliable motor protection unit protects the pump 24 hours a day whilst monitoring energy consumption.

The MP204 protects pump motors against under-voltage, over-voltage and variations in power supply ensuring the pump continues its steady performance. The pump motor will be protected against the overheating which accompanies such variations and reduces pump lifetimes.
