ASME Bladder Tanks, Storage Tanks & Pressure Vessels

Non-ASME Hydropneumatic Tanks

FX bladder style tanks are non-ASME code design. FX tanks will be smaller in size than the plain steel hydropneumatic tank design and thus require less floor space. The heavy-duty butyl rubber replaceable bladder is a barrier between the air and water which prevents water logging. The pre-charged hydropneumatic tank is virtually maintenance free. Sizes from 2 to 528 gallons. Standard design working pressure 150 PSI.

FX Hydropneumatic Tanks:

FX series hydropneumatic tanks are designed to accept water between two set pressures usually controlled by a pump switch in pressure booster, water well, shock and surge, as well as other commercial and industrial systems where water is to be stored in a corrosion protected reservoir.
