Hydroguard

HYDRAULIC SHOCK ARRESTORS

HydroGuard™ Series

The HydroGuard™ series has been specifically designed for hydraulic hammer arresting applications. Featuring the latest diaphragm technology HydroGuard™ shock arrestors are built to reduce or eliminate hydraulic shock, otherwise known as water hammer.

Flow-Thru

MAINTENANCE FREE PRESSURE TANKS

FlowThru™ Series

The FlowThru™ range of tanks is ideally suited for systems where the water stored in the tank is not circulated due to a maintained level of continuous pressure in the system. Every model in the range has been designed with a patented FlowThru™ connection which diverts system water into and, more importantly, out of the tank while the pump is running. This constant flushing action assures that the water in the tank remains as fresh as possible and eliminates the possibility of stagnant water during normal system operations.

Flow-Thru
Challenger Series

MAINTENANCE FREE PRESSURE TANKS

Challenger™ Series

With a chlorine resistant 100% butyl diaphragm, incorporating a precision molded polypropylene liner, the Challenger™ Series tanks offer superior air and water separation. The CAD-2 diaphragm and liner assembly containing drawdown water are sealed together with a positive lock internal clench ring. An ‘air buffer’ prevents the water chamber from being in contact with the tank wall in order to minimize condensation issues.
