The pressure in the dredge pump is always increasing. Giving extra wear and tear on the seal. The HY seal is tested at several sizes of pumps and at this moment the HY seal is ready to be implemented at all pumps. The seal is composed of components which are always on stock at our warehouse. Using a HY seal means that the down time for replacing standard wear parts can be caped to a minimum. The HY seal is used in our dredge pump, but on request the HY seal can be designed to fit every type of dredge pump.
