Conveniently located for easy pressure adjustment
Projection-welded for durability

2. DESIGNER FINISH

High gloss exterior powder coat
Provides positive protection against corrosion and UV rays

3. BUTYL RUBBER PARABOLIC DIAPHRAGM

Eliminates rubbing on the tank wall or rolling over on itself

4. STEEL SHELL

5. STEEL RETAINING RING

6. POWDER-COATED WATER CHAMBER

Proven protection against internal corrosion

7. CORROSION-RESISTANT BASE

High-impact polymer material
Strong and stable for long life
Base rotates for easy alignment to pipe connection
Slotted and noted for air flow, reduced condensation buildup

*With pump stand.

***In keeping with current industry standards, drawdown factors are based on Boyle’s law. Actual drawdowns will vary depending upon system variables, including the accuracy
and operation of the pressure switch and gauage and operating temperature of the system.
Caution: install a pressure relief valve on any installation where the pump pressure can exceed the tank’s maximum working pressure.
NOTE: Precharged tanks cannot ship via air freight.
