Whale In-line Pressure Switch
Switches the pump on or off by detecting the change in pressure in the water system.
Fitted in-line, the Whale Pressure Switch provides a simple and convenient way of creating a pressure system with an electric pump that does not have its own switch. The Pressure Switch is normally fitted close to the pump on discharge side (before any in-line Y piece). The Pressure Switch detects the opening and closing of any tap in the system. An in-line filter is recommeded on the inlet side to prevent dirt from entering the pump or switch.
What it does:
The Whale in-line Pressure Switch features a built in non-return valve and adjustable setting screw to allow the system to be fine-tuned to compensate for drops in battery voltage. The switch's setting knob is used to adjust the cut-out pressure within the range of 5 to 25 psi (0.4 to 1.7 bar). Regardless of the cut-out pressure, teh differential between cut-out and cut-in is fixed at approximately 3 p.s.i (0.2 bar).The Whale pressure Switch is recommended for simple pressure systems.
