Hydrostatic Testers

6334 Series

Our Most Popular Hydro-Test Hydrostatic Testers

The cost of hydrostatic testing can be reduced as much as 90% using General Pump & Equipment's 6334 Series Hydro-Test Hydrostatic Testers. These electric powered units are portable, easy to use, rugged and money saving. The test pump is designed to work best with water pressure feed but will operate with gravity feed where water pressure is not available. The 6334 Series is excellent for testing piping systems, boilers, automatic sprinkler systems, fire hoses, and extinguisher tanks.

Model 6334-350 testers are the standard of the industry for low pressure testing. Used by contractors, fire departments, and fire equipment dealers thousands of times each working day.

Your Hydro-Test Hydrostatic tester is cased in a powder coated 16 ga. steel box. Units are equipped with an easily adjustable relief valve that can be set for any pressure up to the maximum pressure for your unit.  Units have brass and stainless steel fittings, 1/2” y-strainer on inlet plumbing, glycerin filled pressure gage, high pressure check valve, 7' electrical cord, and a 10' high pressure hose.
