AR4 Series

Air Powered Hydrostatic Testers

The AR4 Series Air Powered Hydrostatic Testers provide pressure up to 3000 PSI. They are completely portable, safe, rugged, money saving and can be used whenever hydrostatic testing is necessary. Size, height and volume of the system being tested present no problem. Units are designed for use with water, but will operate with other liquids including oils, glycols and fluids compatible with Buna-N materials.  

All AR4 Series testers are self priming and will easily draft liquids from a tank or barrel. Units will also work very efficiently with standard water pressure. AR4 Series testers can be used as transfer pumps as well. Liquids can be pumped hundreds of feet high if needed. These units are equipped with an easily adjustable relief valve that may be set for any maximum pressures needed to do the job. All units are shipped ready to operate and fully tested.  

Equipment included: All necessary piping needed for testing, liquid filled gage, backflow prevention check valve, totally adjustable relief valve and a brass Y-strainer on the inlet piping. All air controls (Filter, Lubricator, Regulator) are included. Units supplied with portable pneumatic tire cart and a 15' high pressure outlet hose.
