LIGHTWEIGHT & PORTABLE: Easy to store and haul, this mini utility pump offers big value in a little packageMULTIPURPOSE: Perfect for transferring water from aquariums, washing machines, water beds, water heaters, clogged sinks, and more.Manual testing pump is the main test instrument of measuring pressure vessel equipment, the highest working pressure of up to 50 kg/cm2.. Within 0 ~ 50kg/cm2 at any stage of the correct pressure for hydrostatic test, widely used in, chemical industry, construction, plumbing, oil, coal, metallurgy, scientific system, shipbuilding and other industries. Special testing of pressure vessels and pressure equipment, piping, valves, rubber fittings and other pressure device under pressure.Operation and maintanence:1.All the components should be inspected if the connection is tight or not before testing pump, pressure gauge is normal or not, in and out of conduit is installed, the pump working medium for 5 ~ 50 ° C water, emulsion or viscosity <; 45mm2;/s of the oil. Ban the use of sediment and other pollutants have no clean water.2. In order to improve the testing efficiency, targeted containers or equipment could be filled with water at first, then connect the pressure of the pump outlet pipe.3. In the process of test, if found air inside,could open water valve until the air come out finally.4.In the process of the pressure if you find any water leaking phenomenon, should stop working immediately for inspection and repair, it is strictly prohibited under leakage continue to increase the pressure.5.After the completion of the test, to loosen the water valve, pressure drop, in order to avoid damage of pressure gauge.6.Do run off the water inside the pump when you put it away after using, sucked into a small amount of oil, to prevent corrosion
