·All pumps should be supplied with a foundation mounting pad. Detailed installation drawings (such as steel plates, joint plate grooves, etc.) should be provided by Nanjing Land Deep Group.

All worn parts, such as sealing surfaces and shafts, should be made of corrosion-resistant materials and be easy to replace. If necessary, a wear sleeve should be provided on the shaft.

·The sewage pump should not require frequent lubrication of the shaft bearings.

·All spare parts are ready for use without calibration.

·Tolerance: Tolerances for machined parts should be indicated on the submitted drawings.

All parts and accessories should comply with Tolerance specifications in ISO standards.

Tolerances should not accumulate. All unavoidable deviations within the aforementioned standards are first approved by the owner.

Acknowledged.

·The ratio of the provided motor power to the main shaft power within the allowable working range of the pump is not less than 1.7 times.

·Electrical materials and motors: All motors comply with specified general requirements, featuring H-class insulation and protection grade IP68.

Excellent rigidity and vibration resistance. The motor's vibration and noise should be minimal. The housing should be securely connected to the grounding wire.

AS30-2CB Submersible Slurry Pump Structure and Performance Description

· Bearings: Select SKF or NTN bearings, properly configure the bearings to extend the pump's lifespan.

·Motor: Motor features F-grade insulation, with a high operating temperature of 155°C, and a protection rating of IP68.

· Mechanical Seals: Utilize two independent mechanical seals in series to separate the motor from the pump, providing dual protection for the motor.

· Impeller: WithPlease provide the Chinese content you would like translated.Excellent flow and speed deliver liquids with high efficiency, preventing clogging.

· Pump Housing: Engineered with CAD/CAM technology for high efficiency and minimal wear.

·Shaft: Pump and motor are coaxial, with shaft end sealing device, ensuring the shaft does not come into contact with the pumped medium, protecting it from corrosion.

·The shaft extension design is kept as short as possible to minimize shaft deflection, reduce vibration, extend the service life of mechanical seals and bearings, and lower operating noise.

· Monitoring System: The stator is equipped with three series thermal control switches. They are in a "closed" state at normal temperature and open when the stator temperature reaches 125℃.

· The oil chamber is equipped with a leak detection probe for leak detection. When there is a leakage in the mechanical seal on the pump side, the oil-water ratio in the oil chamber

At a certain concentration, the oil-water probe emits an alarm signal (the indicator light illuminates) and automatically cuts off the power, stopping the pump from operating.

·Buoy Switch: In case of mechanical seal leakage on the motor side, liquid entering the buoy switch chamber, and the infiltrated liquid reaching a certain height, the buoy switch will emit an alarm signal (the indicator light will turn on) and stop the pump, prompting maintenance personnel to inspect and replace the mechanical seal on the motor side.

·The assembly includes an electric motor, impeller, pump body, and pump cover, etc.

· The pump housing features a mounting foot for stable installation and operation.
