Structural Feature


Electric Single Stage Double Suction Centrifugal Water Pump for Urban Water Supply
1.Sealing
Superior mechanical seal,long term operation without leakage
Mechanical seal,strong interchangeability for universal use by non-asbestos soft packing structure and injection type packing structure
Stainless steel shaft sleeve for easy maintenance
Half packing gland,large space for packing replacement

2.Protective cover
Half-split structure,comply with IE standard,safe and reliable
 
3.Casing
Circular pressure chamber design with high efficiency
Double-volute pumping chamber is with balanced radial force and sound strength; bearing and seal are with small force withstanding and long service life
Water suction chamber is with split rib design;inlet is without vortex and noise while with stable operation and sound cavitation performance
The inlet and outlet water channels are coated with smooth wear-resistant coating,and water loss is small
Auto-correct pump cover for easy installation
Inlet DN500 for universal use by vertical and horizontal types
 
4.Bearing
Short span and enlarged diameter design, stable operation and long service life.
Grease lubrication with small and medium pump,online refueling
Provided with online vibration and temperature measuring devices to ensure safety operation
Transfer high temperature liquid,employ water-cooling structure
 
5.Shaft
Bold design,universal use for 50HZ and 60HZ pump shaft,sound rigidity, and stable operation
Full sealing design, no contact with liquid, and easy maintenance
Allow short-time inversion, common shaft for forward and reverse rotations

6.Impeller
Three-dimensional flow theory design employed,CFD calculation simulation,high efficiency, high efficiency zone width, and sound cavitation performance
Provided with modified impeller;comprehensive performance curve is full and wide
Adjacent blade is with staggered design;V-shaped outlet;sound flow state;low pulse;small vibration;and high efficiency
Double seal ring is employed for the casing and impeller to extend service life of impeller;labyrinth seal design is employed for the impeller seal ring to reduce leakage and improve pump efficiency
Metal mold is employed,blank precision casting,CNC machining

 

Ordering Instructions


1.Please provide the following information when placing an order
Pump mode or working conditions data:capacity,head and NPSH(net positive suction head)ect
Medium:working temperature,corrosive or other physical&chemical properties(temperature)>80ºC,cooling structure will be adopted for bearing,the material of casing&cover is QT500-7)
Pump inlet pressure
Type of shaft seal(Users have three choices:non asbestos soft packing,mechanical seals and injection type soft packing.if not to specify it,mechanical seals will be supplied.)
Direction of rotation(Counterclockwise rotation is special.if not to indicate direction,clockwise rotation is to be provided.)
Parts material(If not to specify material,pump will be supplied according to standard material )
Motor requirement:power,voltage,protection class,insulation class,cooling method,anti-explosion or not etc
Common base(standard configuration:when motor support number315 and pump suction diameter350,scope of supply shall include common base.beyond the above scope,it is necessary to specify whether you need pump base or common base when ordering)
2.Model selection instructions
The order is not limited by the performance parameters list.data in the catalogue is only special point parameter,we can design and manufacture the product according to the user requirements
If selected model is close to performance parameters,generally standard impeller pumps and high speed pumps are preferred.(to select high speeds pumps,NPSH shall meet the requirements)
For specific speed of 40,60 and 90 low specific speed pumps, if selected product is not running on large flow and low head operation conditions,motor can be calculated according to the actual operating points and appropriately reduced
Pump can be of speed down running,but generally exceeding rated speed acceleration running is not allowed
