The list of applications for polyurethane (PU) is long, and there are good reasons why the material is in\ndemand. It can be used for cushioning in everything from car seats to packaging, but PU foam is also an\nenergy-efficient and versatile insulation material for pipes, houses, machinery, and more. As such, it is well\nsuited for contributing to the green transformation, reducing our need for heating and cooling \u2013 and\ntherefore our need for power.\n<\/p>\n\n\n\n

Manufacturing PU, however, is a challenge. Liquid isocyanate is a key component in PU, but it crystallises\nupon contact with even small amounts of moisture, causing pumps, seals, and valves to seize up and break\ndown. And because isocyanate is toxic, leakages can have serious consequences for personnel, bystanders,\nand the environment.\n<\/p>\n\n\n\n

Magnetic couplings keep production running\n<\/strong><\/p>\n\n\n\n

With a DESMI ROTAN\u00ae ED internal gear pump, you can avoid these issues and keep your PU production\nrunning safely, effectively, and economically. The most important reason is that the pump is magnetically\ncoupled, and the pump chamber completely sealed. This makes the pump completely tight, preventing air\nmoisture from reacting with the isocyanate, and preventing isocyanate leakage.\n<\/p>\n\n\n\n

Any pump with a non-magnetic shaft coupling and mechanical seals is prone to deterioration because the\nisocyanate will react with even minuscule amounts of air moisture that enter via the shaft seals. Over time,\nthis leads to pump degradation and failure, and you will need to spend time and money on maintenance,\nrepair, or replacement \u2013 and on preventing or treating occupational injuries that result from leaked chemicals.\nQuite simply, the only solution that is reliable and safe in the long term is a magnetically coupled pump such\nas the DESMI ROTAN\u00ae ED.\n<\/p>\n\n\n\n

Ideal for your PU production process\n<\/strong><\/p>\n\n\n\n

The magnetic coupling is the key reason why the ED is ideal for isocyanate applications, and the pump offers\nseveral other features that make it ideal for all stages of your PU production process:\n<\/p>\n\n\n\n
