The B80KGKG3 two-stage pump series represents a significant advancement in the field of plastic centrifugal pumps, offering plant engineers and operators new levels of reliability and safety. As industries increasingly rely on efficient flue gas cleaning, gas scrubbing, and surface cleaning systems, the demand for vertical submersible pumps has risen sharply. These pumps are essential for ensuring smooth, fast, and consistent operation in critical processes.
However, designing plastic pumps presents unique challenges compared to their metal counterparts. While advanced technologies used in metal pumps cannot be directly applied to plastic designs, the B80KGKG3 overcomes these limitations through innovative engineering. Plastic materials have limited thermal elasticity, which means they can't handle the same high bearing loads as metals. This becomes especially important when dealing with large impellers and deep immersion applications.
To address these issues, a modular system was developed specifically for the B80KGKG3 two-stage pump series, operating at a rated speed of 1,450 rpm. This design ensures operational safety and system availability even during continuous use. The pump features two impellers arranged in sequence, allowing it to achieve a lift of up to 85 meters. Its dual-impeller configuration also enhances wear resistance, making it more suitable for handling liquids containing solids or with low lubricity—outperforming single-stage pumps in such conditions.
Another key advantage is its compact installation size, which is crucial in factory engineering where space optimization is a priority. Additionally, the four-pole drive system ensures quiet operation, reducing noise pollution in industrial environments.
With a flow rate of 280 cubic meters per hour and a maximum lift of 85 meters, the B80KGKG3 is designed for versatility. It operates within a temperature range from -10°C to 90°C, depending on the material used. The pump can be submerged up to 4,000 mm, and it uses a dry gas seal to protect the bearings. The motor is equipped with an atmospheric shaft seal, while an optional single-acting standard balanced mechanical seal provides additional protection.
Axial forces are managed by a grease/oil-infiltrated rolling bearing, while radial forces are absorbed by a wide main bearing made of PTFE-GF/ceramic or SiC/SiC, depending on the media being pumped. The pump housing is constructed from polypropylene or polyvinylidene fluoride, with glass fiber-reinforced or coated polypropylene options available for high-temperature applications. This combination of durability, efficiency, and adaptability makes the B80KGKG3 a standout solution in modern industrial pumping systems.
The spotlights can be placed around the ceiling or above the furniture, in the wall or in the skirting line.
The light directly shines on the household items that need to be emphasized, so as to highlight the subjective aesthetic effect and achieve the artistic effect of outstanding emphasis, unique environment, rich levels, rich atmosphere and colorful. The spotlights are soft and elegant, which can not only play a leading role in the overall lighting, but also local lighting to set off the atmosphere.
