WLB series boiler water circulating pump is a wetstator non shaft sealing pump.
The pump and motor are in the closed pressure housing. The shaft seal free design can safely and reliably pump high-temperature and high-pressure boiler water without any leakage.
The motor is a wet stator motor with an inner
chamber filled with boiler water
Reliable Operation
• ANSYS software is used to calculate, simulate and analyze hydraulic components such as pump casing, diffuser and impeller with excellent performance
• Elastic suspension structure with adaptive thermal expansion of pump body
• The pump is integrated without shaft seal (zero leakage of shaft seal) structure
• Water lubricated bearings with high load capacity
• The conductive joint of adaptive outgoing line with reliable sealing and stable insulation
• Anti-fouling device for preventing boiler scaling from entering the motor chamber
* Magnetic filter with high cleanliness
Online standby is safe and reliable
• Heat shield structure with low heat conduction and enhanced air cooling
* Auxiliary cooling device to prevent motor overheating during online hot standby
High efficiency and low loss
* High efficiency hydraulic performance of CFD software optimization design
* High efficiency motor optimized by special wet stator electromagnetic calculation software
• Low water friction wet stator motor with optimized structure
Manufacturing of Boiler Water Circulating Pump
Thermal Electric Generation Project In Year 2005, We developed boiler water circulating pump and supporting auxil-lary equipment with independent intellectual property rights in China. And various types of boiler water circulating pumps for power generation units, such as subcritical, supercritical and ultra (supercritical), are successively developed in succession. At present, the actual manufacturing pressure is up to 40MPa, and the voltage level is up to 10kV. Solar Energy Photo-thermal Generation Project
We took the lead in the first batch of solar thermal power generation demonstration projects of the National Energy Administration.
The forced boiler water circulating pumps of Qinghai Gonghe 50MW tower photo-thermal project, the steam generator boiler water circulating pumps of Xinjiang Hami 50MW tower photo-thermal project and the SGS external circulating pumps of Dunhuang Fresnel pho-to-thermal project designed and manufactured by We have all been put into operation in 2019.
Processing and Manufacturing Equipment We own advanced processing and manufacturing equipment and a complete detection system. It can be used to test 0.4kV, 0.69kV, 3kV, 6kV, 10kV and other motors with different voltage levels. With the ability of designing and manufacturing boiler water circulating pumps and drive motors for subcritical, supercritical and ul-tra-supercritical power generation units,We can meet the maintenance and transformation of various specifications of boiler water circulating pumps, such as various kinds of large and medium-sized motors at home and abroad and productions from Britain, Germany or Japan.
