The AS/AC series consists of high-efficiency, energy-saving vertical multistage centrifugal pumps that utilize centrifugal force generated by impellers to transfer fluids. Engineered with top-tier components—including the main shaft, impellers, guide vanes, mechanical seal, and a standard IEC motor—it ensures seamless, high-performance operation.
- Compact Inline Design:The suction and discharge ports line up coaxially, allowing for direct installation within horizontal piping lines to save premium footprint space.
- Dual Installation Versatility:Supports both vertical (upright) and horizontal (lying down) mounting. For horizontal installations, a dedicated mounting fixation module is provided to guarantee vibration-free, smooth operation.
- Flexible Connection Options:Available in Flange, Pipe Thread, and Quick-Clamp interfaces to match various pipeline standards.
- Premium Metallurgy (Material Classifications):
- S Type (Stainless Steel):Crafted from AISI304, AISI316, or Duplex Stainless Steel (2205). Perfect for clean media, drinking water, and advanced water treatment systems.
- C Type (Cast Iron):Features a cast iron casing for standard industrial clean water boosting. Offers maximum cost-efficiency for budget-conscious projects.
- Heavy-Duty Motor Configurations:Equipped with fully enclosed fan-cooled (TEFC) motors, IP55 protection, and Class F insulation. Single-phase options range from 0.37 to 2.2kW, alongside wide-voltage three-phase options suitable for long-term, continuous heavy-duty cycles.
- Axial Thrust Protection:An optionalThrust Balancing Device is available to drastically reduce axial forces exerted on the motor bearings, dramatically extending the equipment’s service life.
II. Medium & Operating Conditions
- ✅Fluid Compatibility:Suitable for pumping thin, clean, non-flammable, and non-explosive liquids that do not contain solid particles or fibers.
- ✅Wide Temperature Range:
- Standard Temperature Version: -15℃to +70℃
- Hot Water Version: -15℃to +120℃
- ✅ Environmental Limits: Ambient temperature
40℃, altitude
(Note: Oversized motor power configuration is required for higher temperatures or high-altitude operations).
- ✅Anti-Cavitation Guard:Fully integrated with NPSH (Net Positive Suction Head) calculation parameters. A safety margin of 0.5m water head is pre-calculated to protect the pump casing from cavitation damage.
