Product Features
■ Optimize the design of curved pipe flow path for good hydraulic performance.
■ Adjustable blades for high efficiency and a wide efficient range.
■ Slow speed design for stable operation, more conducive to salting out and cold crystallization process requirements.
■ Adopts advanced foreign butt welding shaft technology to meet transmission strength and corrosion resistance requirements, saving costs.
■ More than 95% of domestic alkalilinked enterprises (cold crystallization and salting out processes) use this type of product, with numerous engineering applications from 300 m3/h to 8000 m3/h.
■ Due to the special design of this pump, it can be applied to different positions to increase system pressure and liquid level, or implement forced circulation, making its application range very extensive.
Product Structure
■ The ZLH type pump is a typical vertical axial flow pump, installed vertically and requiring less floor space.
■ The impeller is submerged in the liquid, allowing for direct start without the need for water filling or vacuum extraction.
■ The structure is compact and reasonable, making maintenance easy.
■ The drive mode can be direct coupling or gear reduction drive.
■ The sealing method is power seal or packing seal.
