Robust precision testing pump for pressure testing of water lines and containers up to 60 bar with very high testing standards. Pressure testing with water or oil of piping in residential and industrial construction, as well as for industrial containers (up to 60 bar). Expansion possible with an extra fine scaling pressure gauge (0.1 bar) for testing up to 16 bars. Reliable and precise testing results: the dual-valve system (Twin Valve) enables self-testing of the pump as well as a precise fine adjustment of the pressure. A drag indicator displays the present pressure so that a loss of pressure in the system can be detected easier. Especially precise reading as needed: finely scaled (scaling 0.1 bar) pressure gauge available separately. Testing hose with steel mesh prevents reading mistakes, that can happen when the hose expands during operation. Type 50-S: Weather and cold-resistant steel container with DURAMANT coating. Replacement Against Manufacturing defect (6 Months).
