Product Description
The Franklin FPS-6A-29 is a 4-inch high-capacity multistage submersible bore pump for water supply, tank filling, irrigation and pressure boosting. This 3.7kW single-phase model has a three-wire motor and is supplied with a starter.
The assembly combines a high-capacity pump end with a corrosion-resistant Franklin 4-inch submersible motor. The package includes a cable splice kit.
Applications
- Domestic, commercial and rural bore-water supply.
- Tank filling and stock watering.
- Irrigation.
- Pressure boosting.
Performance
- Flow at 160m head: 100L/min.
- Maximum head: 199m at zero flow.
These are manufacturer reference figures for the pump without a check valve. Valve losses, pipe resistance, pumping water level, delivery height and required outlet pressure affect the installed duty. Use the 6A-29 performance curve when checking the required flow and head.
Construction and water suitability
High-flow hydraulic stages and impeller eye and hub seals help reduce internal leakage. Use in a properly developed bore with minimal sand or sediment.
- Stainless-steel discharge head and motor bracket.
- Stainless-steel hexagonal shaft, shell and shaft coupling.
- Ceramic shaft sleeve and rubber discharge bearing help resist abrasive wear.
- An integrated stainless-steel wafer-style non-return valve is fitted in the discharge head.
- Intermediate bearings support shaft stability in longer, higher-power configurations.
Installation and controls
- Position: keep the complete pump and motor submerged and at least 1.5m above the bore bottom.
- Motor cooling: water must flow past the motor before entering the pump. Fit a suitable flow sleeve where the installation cannot provide the required cooling flow.
- Non-return valve: an internal valve is included; follow Franklin’s installation instructions for any additional valves required by the installation.
Support the assembly with suitable pipework and a safety cable; never lift or suspend it by the electrical cable. Extend the motor lead with correctly sized submersible cable and a waterproof cable joint.
Water temperature: up to 30°C for the standard Franklin motor application. Follow the supplied motor’s nameplate and cooling instructions for the complete assembly.
Automatic tank filling or pressure operation requires suitable level or pressure controls. The starter is included; match the motor protection and cable sizing to the supplied motor and starter. Use dry-running protection where the water level can fall below the pump.
