Pumps for Isocyanate - Plastics & Resins
Isocyanate is one of the components in broadly all foam products such as foam mattresses, inner linings in cars, cushioning in car seats, chairs and sofas. The hard qualities are used for insulation of houses, machines, tubes, etc. There are various types of isocyanate, but common to all of them is that they react to the humidity of the air by forming very hard crystals, which wear out the pumps and mechanical seals, if any. For MDI (Isocyanate) it is recommended to use positive displacement pumps and the leading MDI producers are recommending the DESMI ROTAN® series (magdrive pumps). They have been successfully used for a long period of time at many different applications.
