Speck Resort 110 Impeller – 145mm Diameter, 15mm Blade Width

The Heart of Commercial Pool Circulation

As a retailer of hot tub spare parts, I recognise that the impeller represents the absolute core of any centrifugal pump system. This genuine Speck Resort 110 impeller is the rotating component that transfers energy from the motor to the fluid, converting mechanical energy into kinetic energy to generate the powerful flow rates demanded by commercial pool applications. With its precisely engineered 145mm diameter and optimised 15mm blade width, this impeller delivers the exceptional performance that makes the Resort 110 series the preferred choice for commercial aquatic facilities.

Advanced Centrifugal Engineering

The impeller is the rotating component within the centrifugal pump design, which transfers the energy from the pump’s motor to the fluid. It is made up of vanes that come off an open inlet at the centre, known as the eye, which create a centrifugal force as they spin to move the liquid from the casing to the discharge point. This sophisticated engineering transforms the Resort 110 into a high-performance commercial circulation system.

Performance Engineering Principles

Energy Conversion Mechanism

The impeller works by rotating rapidly within a volute casing to create pressure and flow within the liquid being pumped. It achieves this by using its shape and speed to convert kinetic energy into potential energy as it forces water through the pump system. The 145mm diameter specification ensures maximum circumferential velocity for optimal energy transfer.

Blade Width Optimisation

The 15mm blade width represents a careful balance between flow capacity and hydraulic efficiency. This dimension directly affects the pump’s ability to handle high flow rates while maintaining optimal pressure characteristics. The blade width influences both the pump head and efficiency characteristics, making this specification critical for commercial applications.

Closed Impeller Design Benefits

Maximum Efficiency

This closed impeller design features shrouds on both sides of the vanes, providing maximum mechanical strength and hydraulic efficiency. The enclosed design creates optimal flow paths and minimises internal recirculation losses, ensuring the pump achieves its design performance specifications.

Superior Head Characteristics

Closed impellers provide higher pressure capabilities and steeper head curves compared to open designs. This makes them ideal for commercial pool systems where consistent pressure must be maintained across varying flow conditions, including filtration, heating, and water feature operations.

Enhanced NPSH Performance

The closed design reduces the Net Positive Suction Head Required (NPSH), allowing for more flexible installation configurations in commercial facilities where suction conditions may vary.

Commercial Application Benefits

High Flow Capacity

The 145mm diameter generates substantial circumferential velocity at the 2850 RPM operating speed, enabling the Resort 110 to achieve its maximum flow rate of 110 m³/h. This high flow capacity supports large commercial pools and multiple simultaneous operations.

Pressure Generation

The optimised blade geometry and diameter work together to generate the high pressures required for commercial pool systems, including overcoming filter resistance, heating system pressure drops, and elevation changes to water features.

Operational Reliability

The robust construction and precision engineering ensure consistent performance under the demanding conditions typical of commercial pool operations, including continuous operation and varying load conditions.

Material Engineering

Chemical Resistance

The high-grade engineered thermoplastic construction provides excellent resistance to pool chemicals, including chlorine, bromine, and pH adjustment chemicals. This material selection ensures long-term performance in commercial pool environments.

Dimensional Stability

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

Wear Resistance

The advanced polymer formulation resists wear from sand, debris, and the abrasive conditions common in commercial pool applications, extending service life and maintaining efficiency.

Hydraulic Design Features

Backward-Curved Vanes

The backward-curved blade configuration provides optimal efficiency characteristics and stable operation across the pump’s flow range. This design minimises turbulence and reduces noise levels, important considerations for commercial facilities.

Optimised Eye Design

The precision-engineered eye (inlet) design ensures smooth flow entry with minimal losses, reducing the risk of cavitation and maximising suction performance.

Balanced Flow Distribution

The vane configuration ensures even flow distribution around the impeller circumference, reducing vibration and mechanical stress while maximising hydraulic performance.

Installation and Maintenance

Precision Mounting

The impeller features a precision-machined hub designed for secure mounting on the pump shaft. Proper installation ensures correct hydraulic alignment and prevents vibration issues.

Dynamic Balancing

Each impeller is precision-balanced to minimise vibration at operating speeds, ensuring smooth operation and extended bearing life in commercial applications.

Maintenance Considerations

Regular inspection for wear, damage, or debris accumulation is essential for maintaining optimal performance. The closed design protects internal surfaces while allowing for thorough cleaning when necessary.

Performance Impact

Flow Rate Optimisation

The 145mm diameter is specifically engineered to achieve the Resort 110’s maximum flow capacity while maintaining efficiency across the operating range. Larger impeller diameters generate higher flow rates and pressures but require more power.

Energy Efficiency

The optimised blade width and geometry ensure maximum energy transfer from the motor to the fluid, minimising power consumption while achieving design performance levels.

System Integration

This impeller is specifically designed to work in harmony with the Resort 110’s diffuser, casing, and mechanical seal assembly, ensuring optimal hydraulic matching and performance.

Commercial Facility Benefits

Reduced Operating Costs

The high-efficiency design minimises energy consumption in commercial facilities where pumps operate continuously, resulting in significant operational savings.

Maintenance Scheduling

The robust construction and materials allow for predictable maintenance intervals, important for commercial facility planning and budget management.

Performance Reliability

Consistent hydraulic performance ensures commercial pools maintain proper turnover rates and water quality standards required by health regulations.

Quality Assurance

As a genuine Speck component, this impeller meets the manufacturer’s exacting standards for dimensional accuracy, material quality, and hydraulic performance. The engineering represents decades of German pump technology development, ensuring reliable performance in demanding commercial applications.

This impeller represents the culmination of advanced hydraulic engineering, precision manufacturing, and materials science, making it an essential component for maintaining the exceptional performance standards that commercial aquatic facilities demand from the Resort 110 pump series.
