Pump tanks/ Well tanks:
Specification :

TankPAC Diaphragm Tank because of the diaphragm and pre pressurized air cushion can function to protect the pump and extend the long-term performance. All the tanks are using stainless steel connections. The diaphragm tank totally separates the water and the air, providing a closed system for drinking water preventing the growth of bacteria and vermin intrusion.

TankPAC Diaphragm Tank can create stable pressure throughout multi-level systems providing a pressurized water supply. This pressurized water system eliminates the disparities of gravity fed systems and venting requirements associated with them.
