Shaft Seal
l Packing Seal: The packing shaft seal is a common shaft sealing method. It has a simple structure and is easy to maintain, but it must use shaft sealing water. The pressure of the shaft sealing water is 0.2-0.3MPa higher than the pump outlet pressure. The functions of the shaft sealing water: cooling, lubricating, and flushing .
l Expeller Seal: When the positive pressure value at the pump inlet is not greater than 10% of the pump outlet pressure value, the expeller shaft seal can be used for single-stage pumps or first-stage in multi-stage pumps. The expeller shaft seal does not require shaft sealing water and does not dilute the slurries. It has good shaft sealing effect.
l Mechanical Seal: It is our company's newly developed pump shaft seal device for the slurry pump that transports solid material. It is easy to install, has strong versatility, and can run in the slurry for a long time without leakage.
Structure: PH series slurry pump are cantilever, horizontal, axial suction centrifugal slurry pump. The position of the discharge port of the pump can be installed in eight different angles at intervals of 45 degree per customers’ requirement. The bearing assembly adopts the international leading cylindrical structure, which is convenient to adjust the gap between the impeller and the throat bush, and can be disassembled as a whole during maintenance, and is lubricated with special grease.
