Polyol and MDI are stored in separate tanks. Components are metered by means of all stainless steel non- reacting SS 316 self priming bi-directional positive displacement rotary pumps fitted with Teflon coated dry running DU bush bearings. Three piece designs make the pump easy for cleaning and maintenance.

Metering
Low revolution volumetric gear pumps supported by suitable gear boxes, offers unmatched accuracy in out put and ratio management. Apart from reducing wear and tear to the moving parts low revolution is also suitable for all types of PU system including high viscous system.

Both components are circulated through heat exchangers which has a bundle of steel tubes and cold water circulation facility, Electronic metering management and visual display of real time operating parameters and safety cut off in the event of pressure shoot up provided.

Mixing Head
The heart of PU foaming equipment is the mixing head. Elastofoam LP mixing heads are designed to prevent head blockages during production. Both ISO & Polyol are kept mechanically separate inside the mixing head to prevent cross contamination. Continuous recirculation of components through the mixing head keeps the flow lines clean and always operational. The internal of the mixing head is designed to achieve a homogenous mixture and laminar discharge in to the mould. Head MOC: Hardened alloy steel.
