Waterway 310-4190 Executive Pump Impeller – 4.0 HP (New Style)
The Waterway 310-4190 is a replacement 4.0 horsepower impeller for select Waterway Executive-series pump wet ends (commonly used on 48-frame and 56-frame Executive configurations). Replacing a worn or damaged impeller can restore proper flow, pressure, and overall pump performance.
Key Features
- Replacement impeller for Waterway Executive pump wet ends
- Rated for 4.0 HP applications (impeller thickness/design matches the 4 HP output)
- Often identified by a blue dot marking on the impeller face (common identifier for 4 HP)
- OEM-style fit for compatible Waterway Executive pumps
Specifications
- Manufacturer Part Number: 310-4190
- Type: Pump Impeller
- Series: Executive (select 48-frame / 56-frame wet ends)

Compatibility Notes
- Designed for select Waterway Executive pump models and wet ends that use the 4.0 HP impeller.
- Always verify compatibility by matching your existing impeller’s part number/markings and your pump’s wet end series/frame style.
- If your pump is labeled Executive but uses a different horsepower impeller, do not substitute—match the correct impeller for your motor output.
Recommended Service Items
- Whenever the wet end is opened, it’s strongly recommended to replace the pump shaft seal to prevent leaks after reassembly.

Maintenance Tips
- If you notice reduced flow, poor jet pressure, or unusual noise, inspect the impeller for debris or broken vanes.
- Keep baskets and filters clean—restricted flow can increase wear on the impeller and seal.
- After replacing an impeller, check for leaks at start-up and recheck after the first heat/cool cycle.
- Do not run the pump dry; lack of water can quickly damage the seal and impeller.
