Air-Driven Pump Used For Testing Fire Hose

Issue 10 and Volume 128.

Air-Driven Pump Used For Testing Fire Hose A small, air-driven pump for hydraulic tests of fire hose has been developed by the fire department at the Lewis Research Center of the National Aeronautical and Space Administration in Cleveland. If it is more desirable, an electrically driven pump can be used. A small positive displacement pump and the necessary piping gages and valves are all mounted on a four-wheel cart. There are manifold connections on the pump discharge for attaching the hose to be tested. A hose from any water source is connected to the pump and conventional valves and a pressure regulator control the pressurizing of the hose with water for testing. Hose can be tested for pressures up to 260 psi, leakage, coupling slippage, twist, elongation, warp and rise. The fire department at Lewis Research Center used commercially available components in building the test pump. The pump is rated…
