ROTAN® ED pumps ensure uninterrupted isocyanate handling in PU production

Thanks to their magnetic couplings, DESMI ROTAN® ED pumps do not seize up when handling isocyanate, helping your PU production run safely, effectively, and economically.

With a DESMI ROTAN® ED internal gear pump, you can avoid these issues and keep your polyurethane (PU) production running safely, effectively, and economically. The most important reason is that the pump is magnetically coupled, and the pump chamber completely sealed. This makes the pump completely tight, preventing air moisture from reacting with the isocyanate, and preventing isocyanate leakage.

Any pump with a non-magnetic shaft coupling and mechanical seals is prone to deterioration because the isocyanate will react with even minuscule amounts of air moisture that enter via the shaft seals. Over time, this leads to pump degradation and failure, and you will need to spend time and money on maintenance, repair, or replacement – and on preventing or treating occupational injuries that result from leaked chemicals. Quite simply, the only solution that is reliable and safe in the long term is a magnetically coupled pump such as the DESMI ROTAN® ED.
