Pumps Protection & Control Relays

“HOW TO GET THE MAXIMUM PROTECTION FOR SUBMERSIBLE PUMPS WITHOUT LEVEL SENSORS AND WITH THE MINIMUM COST”

Fanox, one of the main specialists in the world on electronic protection engines, have designed a complete range of electronic relays for submersible and surface mounted pumps protection, that covers almost all the needs of the pumps without changing brand.

Fanox relays are much more reliable and affordable than the relays that are used with level sensors and are the only ones in the market that control the three phases of the motor supply, protecting from empty pump, cavitation, etc. Indeed, they are also the only ones on the market with thermal image, this is very important, because they control with accuracy the heating and cooling of the pump during all cycles, starting, working and stopping cycles. This feature makes almost impossible to burn up a pump.

“We have the authority to say this because we have tested and verified that the rest of the devices in the market only protect one phase, which in some cases can bring out serious problems. We have a complete and specific study on The advantages of electronic protection versus protection with level sensors available for all those customers who request it.”

The leading companies in this sector now use these relays with a high level of satisfaction, due to the good results that they are getting.

PF-R – Pump Protection | Three phase by COS φ

  • No need of level sensors to detect dry running
  • Designed for 3-phase motors from 1 to 630 A and over.
  • Precise motor heating and cooling memory
  • Thermal image
  • Visual indicator of tripping cause
  • Adjustable reset time for cos φ

P – Pump Protection | Three phase by Undercurrent

  • No need of level sensors to detect dry running
  • Designed for 3-phase motors from 1 to 630 A and over.
  • Precise motor heating and cooling memory
  • Thermal image
  • Visual indicator of tripping cause
  • Manual, remote and automatic reset

PS-R – Pump Protection | Single Phase

  • No need of level sensors to detect dry running
  • Designed for 1-phase motors from 3 to 16 A
  • Precise motor heating and cooling memory
  • Thermal image
  • Visual indicator of tripping cause
  • Adjustable reset time for I<
  • By monitoring undercurrent it avoids problems caused by dry running, cavitation, etc
