HDA 65 Hydrant Test Assembly

Allied Pumps’ Hydrant Test Assembly is a calibrated test unit capable of high accuracy tests on-site to establish exact mains capability. With the onus on the designer to establish the extent of equipment requirement for fire and/or water supply, exacting test equipment is essential.

The Fire Hydrant Test Assembly – HDA 65 is an ideal test instrument to establish flow versus pressure mains characteristics. Quick and easy assembly on-site with simplified test procedures ensure minimum time and site disruption.

High accuracy test instruments are pre-calibrated on NATA test facilities and certificates are issued. Allied Pumps’ can also co-ordinate yearly test re-calibrations to guarantee long term accuracy. Pressure reading is obtained via a 0-1600 Kpa large face glycerine filled gauge. Flow readings are digital with instant and totalized flow readings displayed simultaneously.

Robust stainless steel construction ensure extended service life and maintained test efficiency.

A stand pipe allows for connection to below-ground street hydrant. Alternatively a flow measurement pipe connects directly to a building hydrant.
