Description Water Jet Suction Pump Valve | GF P20 Specification Dimensions d16/DN10 – d90/DN80, ⅜” – 3” Materials PVC-U, PP-H, PVDF Gasket materials EPDM, FKM Connections DN10 – DN20 Threads DIN/ISO DN20 – DN50 Screws DIN/ISO DN65 – DN80 Cement spigots DIN/ISO Nominal pressure PN10 Product standard EN ISO 21787 Test standard ISO 9393-2, EN 12266-1 Valve handling Installation notes: • We recommend installing the water jet pump between two detachable pipe sections. • With a view to subsequent dismantling, it is useful to provide shut-off devices. • Relaxation zones of at least 5 x DN are to be provided upstream and downstream of the pump. • It is recommended to install a flow meter in the suction pipe to provide information on the suction power of the pump. • It is useful to install manometers upstream and downstream of the jet pump for reading the inlet pressure and the back pressure. • The suction time can be significantly reduced by installing a check valve in the suction pipe. • Inlet and outlet pipes must have at least the nominal diameter of the pump. • An exact dosing of the propellant and suction flow is guaranteed through the installation of throttle valves.
