HPJ Jet Pump
The HPJ Jet pump from Fomtec is constructed for a pre-calculated water flow. It creates a high pressure drop in the feeding line, caused by the high pickup rate, which has a maximum of about 60%.
Foam is drawn through a pick-up tube from a container at atmospheric pressure. The pre-set flow of foam concentrate is continuously added to the water stream.
The HPJ Jet pump is specially designed for use with high flow nozzles. A special control valve built into the base of housing secures this outstanding performance.
A non-return valve prevents water flowing back into the foam container, once the water supply is turned off or waterflow is to low.
The HPJ Jet pumps variable in-line inductors are used to mix foam concentrate with water when the foam concentrate is supplied from a tank at atmospheric pressure. This in-line inductor is designed to proportion large amounts of concentrate.
Recommended Foam Concentrates
The inductor performs with all types of foam concentrates, including high viscosity alcohol resistant concentrates at 1% or 3% proportioning rate. 6% Proportioning is optional.
The HP inductors could be delivered with the following options:
- Stortz, BS336, NH or other couplings
- Different mixing ratios
