SK-30 Control Unit with Manometer 1" - Automatic Pressure Switch, Dry-Run Protection, For Pumps up to 2200W

Product detailed description

The SK-30 1" control unit protects the pump against dry running. For pumps whose motors do not draw more than 30 A of current during operation. The device is designed to work with clean water free of mechanical impurities. The SK-30 1" control unit is a device used for efficient pump operation control and pump protection. The SK-30 1" controls the pump's operation by monitoring changes in water pressure and water flow in the pipe. Automatic start-up depends on a drop in water pressure in the water system below the set switch-on pressure and on the flow rate in the pipe on which the SK-30 1" is installed. In practice, the SK-30 1" control unit switches the pump on when a tap is opened (or sprinklers are turned on) and switches off after the tap is closed (or sprinklers turned off). Built-in protective functions of the SK-30 1" unit Protects the pump against dry running. In case of insufficient water, the controller switches off the pump, preventing damage. Protects the installation against flooding caused by small leaks. Protection against overvoltage and undervoltage Advantages of the SK-30 1" control unit The unit is very easy to operate. Built-in check valve Manual "AUTO / RESET" switch Power indicator LED "On" LED indicating pump operation "Pump on" Flashing LED indicating lack of water "Water shortage (flashing)" Flashing "AUTO / RESET" LED indicates frequent switching on and off Automatic tuning for installation An arrow is stamped on the housing showing the correct direction of flow. The device's switch-on pressure can be set between 0 and 10 bar. The device can work with a pump that produces a pressure of no less than 2 bar at the inlet to the SK-30 unit. Use of the SK-30 1" control unit The SK-30 1" control unit can be used to control both submersible and self-priming pumps. The maximum water temperature should be below 100 °C. It pumps clean water free of abrasive substances, iron or iron oxides; otherwise there is a risk of damaging the control unit. A small expansion tank can be installed to increase the flexibility of operation. The device must be installed on the pump's discharge side, in a vertical position, between the pump and the first water outlet. If the device is to be operated in an installation where the pressure exceeds 10 bar, a pressure-reducing valve must be installed upstream of the device to reduce the pressure. The best way to seal the SK-30's connections to the pipes is with Teflon tape. Due to the possible interruption of flow between the pump and the device, check valves should not be installed between these devices. The device may only be installed by a person who is thoroughly familiar with the operating instructions and has the appropriate hydraulic and electrical qualifications.
