High Pressure PU & PIR foaming machine, HPM 28/28

This machine mainly consists of
-1 set of piping and flexible hose incl. mixing head,
-1 set of magnetic coupling for Iso only
-2 sets flow meter for Iso and Polyol and display on monitor
-2 sets of pressure gauge for delivery side

Main feature:
1. High pressure PUR foaming Machine for 2 components system
There is a common base frame made of welded steel construction for supporting the metering units, filters and electrical pressure switches.
Each metering unit is separately fitted for the Polyol and Isocyanate, and consists of an axial piston pump, coupling, flanged A.C motor, pump support and safety valve.
The pump output can be adjusted infinitely by hand-wheel and scales fitted to the pump housing.
There is an automatic flushing device for the double mechanical shaft seal.
The pressure control device is separately fitted for the polyol and isocyanate circulating system and consists of a pressure valve set at 250 bar.
It is possible to control the minimum admissible pump pre-pressure as well as the minimum and maximum admissible foam pressure. The control unit consists of an electronic pressure gauge and indication device for the pre-pressure as well as for the high pressure circuit.
There is a component filter, designed as edge filter for polyol and isocyanate.
The edge filter is cleaned manually.
Electric control panel is PLC type including additional component metering unit.
