1) ASME HYDRO PNEUMATIC WELL TANKS

Our Water Well Pressure Tanks are designed according to the ASME CODE Section VIII – Div. 1 using the latest technology in terms of manufacturing processes and quality control.

Available in 150 psi maximum working pressure. Intended for use in hydropneumatic systems, these tanks maintain the system pressure when the pump is not operating and protects the pump by reducing the number of startups.

All models are fitted with a replaceable bladder

2) ASME HYDRONIC HEATING EXPANSION TANKS

Vi energ Expansion Tanks are designed according to the ASME CODE Section VIII – Div. 1 using the latest technology in terms of manufacturing processes and quality control. Available in 150 psi maximum working pressure. Intended for use in hydronic heating systems, these tanks accept the expanded volume of hot water keeping the system pressure below the relief valve setting, thus preventing dangerous pressure build-up. All models are fitted with a replaceable bladder.

FEATURES & BENEFITS
ASME Code Section VIII, Div. 1 U Stamped
Max Working Pressure 150 psi
Max Temperature 240° F (115° C)
Factory Precharge Pressure 12 psi
Models up to 12.0 gals. “two shell” design
Models from 21.0 gals. “two shell and body” design
HTL Bladder Seamless bladder for longer life.
Removable Bladder Removable bladder isolates water from the tank eliminating corrosion and rust in the water.
Stand Heavy Duty reinforced Stand on all models.
Strainer Strainers keep the bladder wide-open during operation, eliminating water stagnation, and keeps out water debris.
Connection Carbon steel water connection.
HTS Air Valve Air valve inside a protective nipple and secured by a galvanized threaded plug.
Finish "Automotive" gray finish paint.
3) THERMAL EXPANSION TANKS

Our Thermal Expansion Tanks are designed according to the ASME CODE Section VIII – Div. 1 using the latest technology in terms of manufacturing processes and quality control. Available in standard 150 psi maximum working pressure. Intended for use in commercial and industrial fresh potable hot water applications, these tanks accept the expanded volume of hot water keeping the system pressure below the relief valve setting, thus preventing dangerous pressure build-up. All models are fitted with a replaceable bladder.

4) ASME 200 PSI DOMESTIC BOOSTER TANKS

Our ASME replaceable booster bladder tanks can be use specifically in a booster pump application, it can provide water to the system during periods of low to no flow shutdown of the booster pump. In a well water application, it can provide the desired volume of water required between the pump shut off pressure and the pump cut on pressure. In an irrigation or sprinkler pump application, our booster tanks will provide a cushion to maintain necessary pressure so the jockey pump will not short cycle.

FEATURES & BENEFITS
  • ASME Construction
  • Minimize Pump Run Times, Extends Life of Pump
  • High Maximum Operating Temperatures
  • 200 PSI Maximum Working Pressure
  • Higher Working Pressures Available – Please contact us for pricing and lead time
