4. Product Features
The pressure acting on the shaft seal is balanced by the balance hole on the auxiliary blade or impeller. The shaft seal can be either a soft packing seal (which can be cooled or not) or a single or double end non-equilibrium mechanical seal of various structures. The ball bearing is durable and the shaft diameter is sufficient to ensure smooth operation. The pump body of some specifications is designed as a double screw shell to balance the radial force. The bearing frame, including shaft, impeller, stuffing box, etc., forms a combined part, so that the pump body does not need to be removed from the pipe during maintenance (if the extended coupling is used, the motor does not need to be removed). The flange design adopts PN16 and PN25 (according to the difference of materials).
5. Use needs
(1) Regularly fill the bearing box with high-quality calcium base grease and replace the wearing parts
(2) If cavitation occurs when the pump is running, it must be stopped within 1 minute.
(3) When the pump is shut down for a long time, the inner flow passage of the pump shall be cleaned.
(4) If the power is cut off suddenly when the pump is running, the power must be turned off immediately and the outlet valve must be closed.
(5) The noise of the pump is ≤ 95dB. In case of vibration and noise, the pump should be shut down for inspection and troubleshooting before operation.
(6) The pump shall be used under suction, and the pump shall be filled or vacuumized before starting; The pump is used under the condition of reverse filling. Before starting, the pump shall be filled with the infusion fluid. After the air in the pump is expelled, the gate valve of the discharge pipe shall be closed.
