Type 390, D85

With the split mechanical seal Type 390, Type D85 is oriented to customer benefit. The emphasis is on perfect technology, high reliability, and the lowest possible procurement and operating costs. Units with split mechanical seals are leakage-free, but despite that, they don’t need to be dismantled to replace the seal or its spare parts. Production losses and expensive, complex maintenance work are avoided. This applies to large and complicated units. The extra cost of a reliably operating split mechanical seal bears no comparison to the possible mounting costs of a non-split mechanical seal.
