East Dcc-M Multi-Stage Shielded Pump for High-Rise Building Pressurization

Product Overview                     

Product Features                        

• The pump and motor are designed in an integrated manner. A canned motor and an energy - efficient impeller - diffuser stacked structure scheme are adopted, making the pump and motor an absolutely sealed unit, ensuring high efficiency, no leakage, and maintenance - free operation.
• The pump selects an efficient hydraulic model and adopts CFD optimization design. The impeller and diffuser are made using stainless - steel stamping and laser - welding technology, with a smooth surface, which improves the pump's hydraulic efficiency and cavitation performance.
• The finite - element analysis method is used for strength calculation, making the pump operate more reliably and durably and extending its service life.
• The outer surface of the motor is decorated with polished stainless - steel pipes. The junction box is arranged on top of the motor. The canned motor cooling adopts an external - circulation form with a modular structure, making it easy to disassemble for inspection and maintenance.
• The pump part adopts a hydraulic balance disc structure, which automatically balances the axial force, resulting in almost no axial load during operation.
• The bearings can be made of SiC or graphite materials, and their installation dimensions are interchangeable.
• There is only a static seal without a mechanical seal. The motor housing adopts a welded structure, achieving complete leak - free operation.
• The motor bearings are cooled and lubricated by the self - conveyed medium circulation, eliminating the need for oiling.
• The motor is cooled by the self - conveyed medium circulation liquid instead of a fan, and a hydrodynamic bearing is used, resulting in smooth operation, low vibration, and low noise.

Product Applications                  

• Water Supply: High - rise building pressurization, water plant filtration and transportation, water plant zonal water delivery, main pipe pressurization; Industrial Pressurization: Process water systems, cleaning systems, high - pressure flushing systems, fire - fighting systems.
• Industrial Liquid Transportation: Cooling and air - conditioning systems, boiler feed - water and condensation systems, machine - tool matching; Water Treatment: Ultrafiltration systems, distillation systems, separators.
• Conveyed Medium: Clean water or other media with physical and chemical properties similar to clean water, with a temperature range of -15°C - 95°C. The temperature of the conveyed medium shall not be higher than the specified maximum temperature of the conveyed medium for the motor.
