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.
