Hot and cold feed straining

Hot and cold feed straining

VMI Rubber offers reliable straining systems that filter contaminations from your compound. This will improve your compound quality which is used for high end products. Our gear pump systems are fed by a single screw extruder that allows processing of compounds with a low or a very high viscosity.

The separately driven single screw extruder provides the needed plasticization for every compound viscosity. It also lowers the costs on spare parts, since well plasticized compounds result in long life time for your gear pump and bearings.

The screw delivers the rubber, free of entrapped air to the gear pump at an adjustable pump inlet pressure. Fine mesh straining, e.g. 180 mesh, is possible with our system. The gear pump is able to build up output pressures up to 500 bar.
The easy access between gear pump and screw allows for trouble-free maintenance and cleaning.

Recommended for long runs of the same compound is a hydraulically operated rapid screen changer that brings a new filter in operation within less than 30 seconds.
