Southern Cross CBI Series Pressure Pumps with Pressure Tank & Pressure Switch

The Southern Cross CBI Series multistage centrifugal pressure pumps with pressure tank and pressure switch are purpose-built for dependable, automatic water pressure boosting in domestic, rural and light industrial applications. By combining a compact multistage pump with a matched pressure tank and factory-set pressure switch, this system delivers smooth, consistent water pressure at every outlet while reducing pump cycling and extending component life.

Constructed from 304 grade stainless steel with a special corrosion-resistant coating, the CBI pump end is designed for long-lasting performance in clean water and potable water supply systems. Each unit is supplied with a brass suction line check valve and a high-quality mechanical shaft seal to help maintain prime, protect the pump from damage and minimise leakage over time. The horizontal multistage design offers excellent efficiency and quiet operation, making it ideal for installation near living or working spaces.

Southern Cross CBI pressure tank systems are a smart choice for household water supply, rainwater harvesting, rural and stock watering, wash down areas and light industrial pressure boosting. The pressure tank stores a reserve of pressurised water between pump cycles, helping to stabilise pressure, reduce energy consumption and lower wear on the motor and switching components. With straightforward access for servicing and easy replacement of common parts, these systems are designed to be simple to install, maintain and support throughout their service life.

INSTALLATION

• Install the pump and tank assembly as close as practical to the water source
• Mount on a rigid, level foundation to absorb vibration and protect the pump
• Provide a weather-proof, well-ventilated enclosure where exposed to the elements
• Ensure adequate drainage around the unit, particularly for indoor installations
• Use suitably sized pipework to minimise friction losses on both suction and discharge
• Ensure a check valve is installed on the suction side to prevent pump cycling
• Set and verify cut-in/cut-out pressures to match the application (if adjustable)
• Installation and electrical connection should be carried out by qualified trades, following local regulations
