| Description |
| Every rotating seal joint will eventually wears out with time and if a seal breaks down, fluid will leak out. Such leakage is especially dangerous with highly aggressive fluids and may result in heavy costs. When delivering non-lubricating fluids or fluids tending to crystallize in particular, the use of mechanical shaft seals requires very complex arrangements like sealing chambers with double-acting mechanical seals. These arrangements are cost-intensive and require a lot of maintenance. What is more, the necessary maintenance intervals considerably reduce the availability of the pump. With Sondermann pumps of the RM type, permanent magnets convey the motor drive to the pump impeller without any contact. Thus, there is no shaft exit requiring an appropriate sealing joint. The wet part and the dry part of the pump are hermetically separated from each other by the rear casing so that leakages through worn sealings are definitely ruled out. The pump does not require any maintenance since optimum sealing is ensured by no need of sealing joints at all. Sondermann RM pumps are always used when perfect leakproofness and freedom from maintenance are indispensable. They are especially used to deliver aggressive acids and bases, degreasing baths, chemicals, highly corrosive liquids or fluids tending to crystallize. Electroplating shops, printed-circuit board manufacturers, purification plants and the photographic industry profit from Sondermann RM pumps. Wherever conventional centrifugal pumps with complex mechanical shaft seals are required, Sondermann RM pumps are ideal for use. |
