Novelties for pumps

We would like to bring a novelty in VALTEC range to your attention – VT.EPC.11 pump automation unit (press control).

The novelty is designed for automatic control of water supply systems pumps and for their protection against operation with “closed gate valve” and from a “dry run”. In case when the pressure in the mains drops below the setup pressure in course of water consumption, the unit starts the pump, thus ensuring water supply to users. The value of cut-in pressure may be set autonomously within the range from 1.5 to 3.0 bar (factory setting is 1.5 bar). Terminated water distribution, pump shutdown takes place with the delay of 8 s, which eliminates the possibility of a hydro shock. If there is no water in the suction line, the unit switches off the pump with the delay of 10–15 s, thus protecting it from the “dry run”. This novelty has one more additional function: automatic reset in case of failure. In case of an accident, the pump automation unit turns off the pump, but will try to start it every 15 minutes. This function will help to automatically put the relay into operation mode, if the accident is caused by a temporary factor, for example, temporary decrease of the water level in the well.

The unit is equipped with a control panel. The built-in pressure gauge ensures visual control of operating environment pressure at the unit output. Relay working contacts are made of silver-nickel alloy not oxidizing in wet conditions. The unit may be used at ambient humidity up to 70 %. Device protection class: IP54. Connecting nozzles thread diameter: 1". Maximum water temperature: 60 °С.

The new unit differs from the previous model by its compactness and lower price.
