ZLB Vertical Axial Flow Pump
ZLB vertical axial flow pump is a small and medium-sized axial flow pump developed by Denor. This series of products has a wide spectrum,good hydraulic performance and novel structure, it is characterized by high efficiency, good cavitation performance, easy installation and maintenance; and the same time, combined with the latest information control technology, the intelligent water pump system independently developed can be configured, with automatic monitoring function.
Application
This series of products can be used for clean water or other liquids with physical and chemical properties close to water whose temperature of conveying medium is no more than 50ºC. They are widely used in large-scale water conservancy projects, farmland irrigation, industrial conveying water. The thermal power station carries circulating water, shipyard level, urban water supply and drainage and water diversion projects.

Product Advantages
High-efficiency energy saving:
the hydraulic model is designed by 3-D flow theory and calculated by CFD computational simulation,with the best performance in theory. Hydraulic components are made of metal mold,cast precisely guide blade mould is machined by CNC;guide blade shell and suction cone blank are cast by resin sand,solid flow channel is completely in accordance with design drawings,with efficiency higher, and wide high efficiency zone.
High reliability:
the design of the inlet flow channel is reasonable, the inlet water is uniform without vortex, with smooth running, the absolute concentricity o the pump shaft, and the excellent static balance of the rotor parts ensure that the pump has low vibration and low noise when running at high speed.
Advanced technology:
all parts using metal mold,precision casting,parts quality is reliable.
Low maintenance:
reasonable structure,convenient assembly and disassembly, and simple maintenance.
Inventory management:
reasonable inventory management,short lead time,fast delivery.
Automatic monitoring:
Equipped with intelligent water pump system independently developed,with automatic monitoring function.
