Each part is then machined on computer controlled equipment to maintain the exact tolerances required for optimum performance. First, they are cast in the US from high quality aluminum then heat treated to a "T-6" hardness for years of service. These are high performance centrifugal pumps designed specifically for operating our dredges and dual-purpose machines. We manufacture one of the most comprehensive series of pumps in the small dredge industry today. The Liquidyne 3-Stage is available for shaft diameters from 35 to 590 millimetres.Engine & Pump Assemblies Outstanding dredge vacuum and long life The condition of the seal is monitored by measuring the water flow from the pump side to the drain of the seal. The water flows from the pump side to the drain of the seal. The helical shape of the grooves and peripheral speed (RPM) of the liner create water flow (similar to aquaplaning) between the grooves and the lip seal. The (water) lubricated Liquidyne lip seals run over a partially grooved bush placed over the pump shaft. The Liquidyne 3-Stage is designed for large abrasive particles (larger than 100 µm) and uses an external flush to lubricate, clean and cool the seal. The stationary housing parts and rubber lip seals that are mounted against the pump housing.A grooved bush that is clamped and rotates with the pump shaft.The seal can be roughly divided into two parts: The order of the modules can vary and depends on the specific application. The Liquidyne seal is made up of different modules and fulfils the following functions: This seal is mainly applied to dredging pumps, sewage water pumps, booster pumps and mining pumps. Optional design: can be designed with divisible housing parts.Hard Metal Layer (HML) coating for extra durable grooved liners.Predictable lifetime due to condition monitoring.
