What Is A Pressure Tank?

A pressure tank (or pressure vessel) is a metal container that can vary in size from 1 L to 3000L. Inside the tank, there is a rubber diaphragm that separates the water room and air room.

How does A Pressure Tank work inside a Pump System?
When the tap shuts, then the water stops flowing and the pressure in the system builds. When the pressure reaches the “off” setting of the switch or controller, then this turns the pump off and the pipes remain pressurized. 

Aquasky has been a member of NSF since 1998. Every pressure tank we build is qualified by NSF drinking water standards and structure safety (NSF 58 and NSF 61). With NSF standard, Aquasky pressure is lead-free, Nitrosamine free and Plasticizer free. About safety, the Aquasky pressure tank is built to contain 3 times maximum working pressure to ensure user safety.
