Basic Introdcution 

Pressure tanks and diaphragm pressure tanks are used for pressurized water systems in detached houses, on farms and in small communities, for example. The tanks are installed into the system after coldwater pumps.

Diaphragm tanks are the most popular type of pressure tanks, replacing the problem plagued bladder tanks. We highly recommend diaphragm tanks over bladder tanks.

Without the need of constant air-control to maintain the desired pressure for your system, all of our diaphragm pressure tanks are pressurized at the factory for quick, easy installation. A durable rubber diaphragm nearly permanently separates the water and air so the tank won’t lose performance due to absorbed air thus nearly eliminating the need for air-injection maintenance.

Volumes 3- 200 liters, up to 1500 liters as custom-made tanks.

We offer a comprehensive and wide range of pressure vessels for heating, thermal, pressure booster, water hammer, reverse osmosis and water well applications

Expansion tanks feature:

• Protect your plumbing in the event of a pressure increase with these quality thermal expansion tanks
• Safely controls thermal expansion by accepting the expanded water and keeping the system pressure safely under the relief valve setting
• Saves water & energy: unlike a pressure relief valve that wastes heated water when activated, these tanks allow the expanded water to be stored in the tank for future use
• Durable stainless steel (Type 304) connections
• Food grade reservoir means the tank works great with potable (drinking) water
• Reduces wear and tear on safety valves, valve stems, and ball seals
• Maximum operating temperature: 200°F
• Maximum working pressure: 150 PSI
• Factory pre-charge: 45 PSI
• Butyl rubber diaphragm, food grade polypropylene liner
• Complies with low lead laws - less than .25% weighted average lead content for wettable surface areas
