Need a special function?
For pump manufacturers we design custom units that monitor temperature, hours, flow and maintenance, with display and ModBus communication.
Which unit controls a 2-pump booster set?
The YNDP02 combines level, alarm, alternation and star-delta starting. If level is already handled, an alternation relay such as the TABV02 is enough.
How do I stop a pump from running dry?
With a level control in the well (TNS020, YNS020) and, as a second protection, a ZCIx4xx minimum current relay.
How many pumps can a single unit alternate?
The MRA005 alternates up to 5 pumps with automatic rotation of the start order; the MRA004, up to 4.
