Bundu Power 450W 48V Solar Pressure Pump

Product Overview

The Bundu Power JETS-3.5-45 is a 450W, 48V DC solar pressure pump for daytime water supply and pressure boosting from storage tanks. Supplied with a pump controller, water level sensors and a 6m solar panel cable with connector, it operates directly from suitable solar panels without requiring batteries or an AC supply. Solar panels are sold separately.

Key Features

• Direct solar operation: Uses solar energy for daytime pumping, reducing reliance on grid electricity.
• Up to 3.5 m³/h flow: Delivers approximately 58 L/min at the low-head end of its operating range.
• Up to 45m head: Provides delivery head for lifting water and overcoming system resistance, subject to the required flow.
• Brass impeller: As specified by Bundu Power for this model.
• Controller and accessories included: Supplied with a pump controller, water level sensors, a 6m solar panel cable and connector.
• 25mm connections: Features 1-inch inlet and outlet connections for integration into suitable pipework.

Applications

• Daytime pressure boosting from a water storage tank.
• Solar water transfer to an elevated storage tank.
• Off-grid water supply and daytime irrigation where the required flow and head fall within the pump's performance curve.

Why Choose This Product?

This pump is a practical option where water can be moved during daylight hours and a suitable solar array can be installed. Its included controller and accessories simplify the equipment selection, while elevated water storage can help make daytime pumping useful beyond sunshine hours through a suitably designed gravity-fed system.

Important Notes

• Solar panels excluded: Bundu Power currently recommends two 620W panels. Have the installer confirm the selected panels' voltage, cold-weather open-circuit voltage and wiring arrangement against the supplied controller's limits before connection. The pump's 48V motor rating is not the controller's maximum PV input voltage.
• Water source position: Follow Bundu Power's installation guidance by placing the water source at or above the pump inlet. Do not select this surface pump for lifting water from a deep well or borehole.
• Performance limits: Maximum flow and maximum head are separate endpoints and are not achieved simultaneously. Actual delivery depends on sunlight, vertical lift, pipe friction and outlet pressure requirements.
• Daytime operation: Direct solar output varies with available sunlight. This package does not provide guaranteed night-time pressure. An optional AC power supply is available separately; confirm the correct accessory before purchase.
• Installation: Use appropriately qualified personnel for the electrical and plumbing installation. Any additional pipework, fittings, mounting equipment and cable extensions must be selected for the installation.
