Special treatment of critical contact surfaces and excellent corrosion resistance

In modern industrial and municipal facilities, pump equipment is the core component of liquid transmission, and its performance and durability are directly related to the operating efficiency and long-term benefits of the entire system. The BPL series vertical single-stage centrifugal pump, as an industry-leading efficient and reliable solution, not only achieves innovation in structural design, but also adopts special treatment measures on key contact surfaces, such as coating protection, thereby significantly It enhances the corrosion resistance of components, effectively reduces performance degradation caused by media erosion, and provides users with a more durable and stable liquid transmission experience.

In industrial and municipal applications, pump equipment often needs to operate in environments containing corrosive media, such as acidic or alkaline solutions, salt water, sewage, etc. These corrosive media will corrode key components such as the pump body and impeller, leading to material performance degradation and even equipment failure. In order to meet this challenge, the BPL series vertical single-stage centrifugal pump adopts advanced coating protection technology on key contact surfaces, which effectively improves the corrosion resistance of the components.

Coating material selection:
Epoxy resin coating: has excellent chemical resistance and wear resistance, and is suitable for the transmission of a variety of corrosive media.
Polyurethane coating: It has good elasticity, impact resistance and weather resistance, and is suitable for environments with large temperature changes.
Ceramic coating: high hardness and good wear resistance, especially suitable for medium transmission containing solid particles, which can effectively reduce wear.
Fluorocarbon coating: It has extremely high corrosion resistance and can resist the erosion of extremely corrosive media such as strong acid and strong alkali.
Coating construction process:
Surface treatment: Before coating construction, the key contact surfaces should be thoroughly cleaned and pre-treated to remove oil, rust and other impurities to ensure good bonding between the coating and the substrate.
Coating thickness control: According to the corrosiveness of the medium and the harshness of the use environment, the thickness of the coating should be reasonably controlled to ensure that the coating has sufficient protective capabilities.
Multi-layer coating: Using multi-layer coating technology, each layer is fully dried and solidified to form a dense coating structure and improve the overall performance of the coating.
Coating performance testing:
Corrosion resistance test: Test the corrosion resistance of the coating in specific media through immersion test, electrochemical corrosion test and other methods.
Wear resistance test: Use grinding wheel wear test, sandblasting test and other methods to evaluate the wear resistance of the coating under the action of mechanical friction.
Adhesion test: Use cross-hatch method, pull-out method and other methods to detect the adhesion between the coating and the substrate to ensure that the coating will not fall off easily during long-term use.

Through the coating protection of key contact surfaces, the BPL series vertical single-stage centrifugal pumps have achieved significant improvements in corrosion resistance, bringing many advantages to users:
Extend the life of the equipment: Coating protection effectively reduces the erosion of key components such as the pump body and impeller by corrosive media, extends the service life of the equipment, and reduces the frequency and cost of replacing parts.
Improve operating efficiency: Coating protection reduces component wear and performance degradation caused by media erosion, ensuring efficient operation of the pump and improving the overall efficiency of the system.
Reduce maintenance costs: Coating protection reduces downtime and repair costs caused by equipment failure, improves equipment reliability and availability, and brings higher economic benefits to users.
Broaden the application scope: Coating protection technology enables the BPL series vertical single-stage centrifugal pump to be suitable for the transmission of more corrosive media, broadens the application scope of the equipment, and meets the needs of more users.

In addition to coating protection of key contact surfaces, BPL series vertical single-stage centrifugal pumps also offer the following advantages:
High efficiency and energy saving: Using advanced hydraulic model design, the pump consumes less energy during operation, which meets the requirements of modern industry for green and sustainable development.
Compact structure: The vertical structure design makes the pump occupy a small area and is easy to install, making it suitable for places with limited space.
Stable operation: Made of high-quality materials and advanced technology, it ensures the stable operation of the pump in harsh environments and reduces the failure rate.
