Hydraulic Design Engineering

Optimised Diameter Specification

The 113mm diameter is precisely calculated to deliver the Resort 30’s design flow rate while maintaining efficient operation across the pump’s performance curve. This diameter provides the optimal circumferential velocity for the pump’s 1.5kW motor rating, ensuring maximum energy transfer efficiency.

Blade Width Engineering

The 13.5mm blade width represents careful hydraulic engineering to balance flow capacity with pressure generation. This dimension directly influences the pump’s ability to generate head while maintaining smooth flow characteristics essential for pool circulation applications.

Closed Impeller Benefits

The closed design features shrouds on both sides of the vanes, maximising hydraulic efficiency and providing superior pressure characteristics compared to open impeller designs. This configuration is essential for applications requiring consistent pressure delivery.

Performance Characteristics

Flow Rate Capability

The 113mm diameter generates the circumferential velocity required to achieve the Resort 30’s design flow rate, typically suitable for pools in the 150-180 cubic metre range. The impeller geometry ensures smooth flow acceleration from the eye to the discharge.

Pressure Generation

The optimised blade geometry creates the pressure rise necessary to overcome system resistance including filtration, heating equipment, and elevation changes. The backward-curved design provides stable pressure characteristics across varying flow conditions.

Efficiency Optimisation

The precision-engineered vane angles and spacing minimise hydraulic losses while maximising energy transfer from the rotating impeller to the fluid, reducing operational energy costs.

Material Engineering

Chemical Resistance

The high-grade thermoplastic construction provides excellent resistance to pool chemicals including chlorine, bromine, and pH adjustment chemicals. This chemical compatibility ensures long-term performance without degradation.

Dimensional Stability

The advanced polymer material maintains precise tolerances under varying temperature conditions, ensuring consistent clearances with the pump casing and optimal hydraulic performance throughout the operating range.

Wear Resistance

The material formulation resists wear from sand, debris, and other abrasive particles common in pool water, extending service life while maintaining efficiency characteristics.

Hydraulic Design Features

Backward-Curved Vane Profile

The backward-curved blade design provides optimal efficiency characteristics and reduces noise levels compared to radial or forward-curved designs. This configuration also provides inherently stable operating characteristics.

Eye Geometry Optimisation

The inlet design ensures smooth flow entry with minimal turbulence, reducing the risk of cavitation and maximising suction performance. Proper eye design is critical for maintaining prime and preventing air entrainment.

Balanced Flow Distribution

The vane configuration ensures even flow distribution around the impeller circumference, minimising vibration and hydraulic losses while providing smooth operation.

System Integration

Resort 30 Compatibility

This impeller is specifically designed for the Resort 30 pump series, ensuring perfect hydraulic matching with the pump casing, diffuser, and mechanical seal assembly. Proper component matching is essential for achieving design performance.

Motor Matching

The impeller load characteristics are matched to the 1.5kW motor specification, ensuring the motor operates within its design parameters while delivering optimal pump performance.

Piping System Compatibility

The flow characteristics complement the 75mm connection size standard for Resort 30 installations, ensuring smooth integration with typical pool plumbing systems.

Application Range

Pool Size Suitability

The Resort 30 with this impeller is typically suited for pools in the 150-180 cubic metre range, providing adequate turnover rates for effective filtration and circulation.
