Inductive inductor ZF series

linefor pipes

The SKUM ZF Inductor consists of a bronze body, foam inlet, metering orifice, and recovery horn. The foam inlet has a grooved connection adaptor and check valve installed by the manufacturer. The body is labeled to show the flow direction and system information such as concentrate type, induction rate, flow rate, and pressure. The orifice is sized by the manu facturer for the specific flow and pressure in which the induc tor will be installed. Standard inductor installations may have suction heights of up to 3.5 m. Total concentrate piping must not exceed the maximum suction height as a combination of friction loss and elevation head loss from the lowest possible foam concentrate level that can be accessed by the suction line. For suction heights above 3.5 m, contact Technical Services. The inductor is installed between two ANSI Class 150 or DIN PN16 flanges. A minimum amount of straight pipe is necessary upstream and downstream of the inductor. For recommended minimum pipe lengths at each inductor size, see dimensions J and K in Table 2. Features Factory calibrated to any flow and pressure within the working range Standard suction height of 3.5 m – suction heights up to approximately 6 m available by request Standard foam induction rates available with SKUM AFFF 3% UG, NFF 3X3 UL201, SKUM ARC 3X3 UG, HOTFOAM 2% High-Expansion, or METEOR X 2% High-Expansion foam concentrates – other agents and induction rates are available by request Can be installed in a horizontal or vertical plane between ANSI Class 150 or DIN PN16 flanges Grooved connection and check valve on the foam concentrate inlet
