50 bar Hydraulic Pressure Test Pump to 12L Double Valve System Robust pump RP50 uses an accurate pressure/tightness test on piping systems and sockets. Applied in pipeline and heating installation. You can also find it used in compressed air, steam and cooling systems, as well as boilers and pressure vessels. As you know, pumps are well suited for filling solar systems or testing in single pressure operation.Here, the Gauge shows the drag pointer setting pressure, so that it can be easily determined when the system pressure drops.The double valve system allows accurate and safe measurements results through setting of accurate pump self-checking pressure.
