Tanks
Expansion, compression and diaphragm tanks for proper system pressurization in hydronic heating and potable water (plumbing) systems.

ASME Expansion Tanks – Series WTA Pre-Charged Tanks
Designed for Potable Well Water and Booster Pump Systems The Series WTA expansion tank is an ASME constructed precharged vessel The WTA tanks will help protect the pump and pressure switches against short cycling The well tank delivers adequate water under pressure between pump cycles to meet the required demand It will provide economical system operation [...] View detailed product page »
ASME Pre-charged "B" and "D" Tanks
Precharged Expansion Tanks contain either a bladder or a diaphragm to separate the air charge from the system water Tanks are design to absorb the expansion forces of heating cooling system water while maintaining proper system pressurization under varying operating conditions View detailed product page »
Compression Tank
The compression tank on a closed hydronic system serves a very important function in providing adequate pressurization under all operating conditions Above all a compression tank must be absolutely air tight BG tanks are available nationally in ASME construction are of black steel construction thoroughly tested and guaranteed leak proof Gauge glass tapping are included as [...] View detailed product page »
Diaphragm Expansion Tanks-HFT, PT
Bell & Gossett expansion tanks are designed to absorb the force of thermal expansion in hydronic heating and domestic potable water systems Series HFT tanks for hydronic heating systems are available in sizes from - gallons Tanks for potable water systems Series PT and PTA ASME construction are available in sizes from - gallons View detailed product page »
HFT Diaphragm Tanks
The Series HFT tank is designed to absorb the force of thermal expansion of heating water and to maintain proper pressurization in a closed hydronic system The heavy duty butyl diaphragm separates system water from the air in the tank preventing water logging problems View detailed product page »
Non-ASME Pre-Pressurized Tanks Series WT Pre-Charged Tanks
Designed for Potable Well Water and Booster Pump Systems The Series WT expansion tank will help protect the pump and pressure switches against short cycling The Potable well tank delivers adequate water under pressure between pump cycles to meet the required demand It will provide economical system operation by minimizing pump starts extending pump motor life [...] View detailed product page »
Potable Water Bladder Tanks
The Series PT expansion tank is designed to absorb the forces of expanding water and protect a potable water system from pressure build up The FDA approved heavy duty butyl diaphragm with polypropylene liner sizes PT- through PT- V and FDA approved heavy duty butyl bladder sizes PT- through PT- completely isolate the water from the [...] View detailed product page »
Tank Purge Valve for Non-Potable Water
The Bell & Gossett Tank Purge Valve TPV is a combination full port ball type isolation valve and drain valve used to connect the system to the expansion tank This valve allows the tank to be drained for easy servicing or tank replacement without having to drain the system Available in various NPT sweat connections from [...] View detailed product page »Legal Information and Privacy Policy ©2012 Xylem Inc.
