Inline Pump Controller for Pressure Boosting

Pump control for pressure boosting by flow detection. The E-Control is ideal for home (domestic) header tank boosting or in-line boosting of low mains water pressure.

Mac3 E-Control is an electronic pressure and flow monitoring pump controller. This means that your pump starting is by pressure/flow sensing and the pump is stopped by flow sensing. When either water flow or a pressure drop is detected, the E-Control activates the pump to maintain pressure in the system until it detects that the flow has stopped then it deactivate the pump.

The restart pressure can be adjusted from the factory default of 1.5 bar by using a dial on the back of the device. This allows the installer to set the restart pressure to anywhere within the range of 0.8 - 2.2 bar.

E-Control can control a single phase pump of up to  2 Hp (1.5kW).

E-Control is mounted inline (or on-pipe) with a 1” (25mm) threaded male connector. It can be mounted in any orientation as the installation or surroundings require. A pressure vessel is recommended and this should be installed in the discharge pipe after the controller.

E-Control has dry run protection built in with a warning light on the control panel to show if there is a system error. Also featured is a ‘Anti-lock’ feature. This anti-lock feature prevents a pump from pump from becoming blocked by starting the pump once every 24 hours, preventing small amounts of sediment from settling inside the pump and causing it to fail, and rotating the shaft ensuring adequate lubrication of the seals.

Dry-run protection is achieved by flow sensing. This protects the pump from running continuously in the event that there is no water present, the pump becomes blocked, or the discharge pipework becomes disconnected from the outlet of the pump. In the event of a dry-run E-Control will shut down the pump and illuminate a warning light until the user intervenes and resets the system.
