Vertical Multi-Stage Centrifugal Pumps

High Pressure Pump

High-efficiency standard motor, Japan NSK bearings and cold-rolled
50ww800 silicon steel sheet made the pump high efficiency, low noise
and mainenance-free. Totally enclosed shaft steel, IP55 protection
grade, F class insulation grade, the special "double-lock" drive and
bearing made the pump withstand higher inlet pressure.

Being produced by the most advance international laser welding
technology no eliminate welding, ensure the high intensity and
efficiency . The processing technology precision casting .CNC lathe,
CNC machining center , the modern advanced technology such as the
laser welding technique and processing equipment.

The pump core parts are designed to be multilevel interlocking,
fastening nut locked, components system interlock assembly industry
to minimize the gap between the impeller per level, improve the
efficiency of the impeller water conservancy, and ensure the stability,
reliability and efficiency of the pump core components.

Balanced & container –type shaft seal with all the parts assembled
together no axial rotating to prevent the shaft and rubber parts from
wearing, with the characteristics of rapid changing ,easy installation
and safe operation. Dynamic sealing is made of cemented carbide
materials and static sealing is fluorine rubber material which makes
the mechanical seal to be high temperature resistance long service
life, easy changing and other significant characteristics.

The built-in floating sealing ring of the pump cavity body could
minimize the internal leakage produced by the differebtial pressure
and prevent the energy consumption when liquid leaking back to the
pump cavity body.

Cold extrusion spline shaft with good surface quality, high machining
accuracy, at the same time improve the comprehensive mechanical
properties of the shaft and the reliability of the pumb.

Model Instruction
Overview Of The Product

BL(T) series stainless steel multi-stage centrifugal pump (afterwards called pump)boasts characters of high efficiency, low noise, steady operation, etc.The pump set adopts the non-self-priming vertical multi-stage structure, which makes a compact whole,its installation easy, its operation and maintenance convenient.

Application Limits
