Note: These configurations are recommended by the manufacturer. Customers may change materials according to specific needs.

Space optimization: Consisting of pump casing, impeller, shaft, bearing house and couplings,etc, the pump is mounted in vertical to minimize footprint while maintaining structural integrity, ideal for constrained installations.
Rapid maintenance: Side-mounted pump inlet and outlet allow pump cover removal for servicing without detaching motors or pipelines. Elastic prestress design is utilized to simplify rotor installation and dismounting without gap adjustments.
Energy saving: Optimized hydraulic models achieve 2-3% higher efficiency than comparable pumps, lowering operational costs.
Seal reliability: The shaft seal is placed in the low pressure zone of the pump casing to extend service life and reduce mechanical seal failure risk.
High serviceability: Only one non-adjustable mechanical seal is utilized with top-mounted placement to enable convenient replacement.
