Light-load multi-stage Pump

Product Overview: This multi-stage centrifugal pump is a revolutionary product developed by our company based on a thorough understanding and adherence to the core design principles of the API 610 standard, specifically for light-load operating conditions.

Core Technology Innovation: Medium lubricated sliding bearing system
· Fundamental Change: This system abandons traditional oil-lubricated rolling bearings, which require complex oil supply and cooling systems, and adopts specialized sliding bearings lubricated by the pumped medium itself.
· Ultra-High Compatibility: The bearing material is carefully selected and processed with special processes to adapt to a wide range of pumped media, ensuring stable operation as long as the media has basic lubricity.
· Integrated Design: The bearing system is deeply integrated into the pump cavity, resulting in a more compact structure and eliminating external lubrication points.

Direct Benefits:
· Reduced Maintenance: No refueling or oil changes are required, eliminating the risk of oil leaks and significantly reducing routine maintenance workload.
·Reduced Costs: Saves on lubricant procurement and waste oil disposal, resulting in lower lifecycle costs.
· More Reliable: Simplified structure reduces failure points and ensures more stable operation.

Typical Applications:
· Boiler feed water and condensate recovery systems
· Industrial cleaning and low-pressure spray systems
· Reverse osmosis water supply and low-pressure desalination systems
· Various clean, non-corrosive, and lubricating chemical processes

This light-duty multi-stage pump represents more than just a product iteration; it represents an evolution of design philosophy. We've implemented a core technological innovation to deliver a brand-new experience that saves worry, effort, and money. It represents a modern pumping solution that perfectly combines cost-effectiveness and reliability.

In June, we carried out a renovation on this multistage pump.
The internal overcurrent section was optimized without changing the structure. Reduce the head and improve the efficiency to better integrate this pump with the on-site process.
Save 140kw/h of energy.
After a month of continuous operation, it has received recognition from the customer.
