Outlet of domestic pump Outlet of domestic pump Hosein Eghbali (Chemical) (OP) 20 Oct 16 06:22 Hi everyone. I've seen a domestic pump with a weird equipment attached to the outlet of it. What is this? Attached File: [img https://www.sendspace.com/defaults/sendspace-pop.h...] RE: Outlet of domestic pump ashtree (Bioengineer) 20 Oct 16 06:53 It looks a lot like a flow controller which turns the pump on when a flow is detected (tap on ) and turns off when the flow stops.

This works on pressure and is usually coupled to a small pressure tank which stores a small amount of pressurized water. When you turn the tap on, the water flows out of the tank, the pressure goes down, once the pressure reaches some set value (adjustable usually) the oump switches on an d pumps until you turn the water off, the tank pressurizes up again and the switch then turns the pump off when it reaches some defined pressure. Remember - More details = better answers Also: If you get a response it's polite to respond to it. RE: Outlet of domestic pump micalbrch (Mechanical) 23 Oct 16 08:52 Yes, that is a pressure switch which starts and stops the pump depending upon the loads. It takes care of a constant pressure, reduces peaks and can even act as a no-flow protection.
