Southern Cross CBI Series Pressure Pumps with Press Control

The Southern Cross CBI Series multistage centrifugal pressure pumps with Presscontrol are designed for reliable, automatic water pressure boosting in homes, small farms and light industrial sites. The integrated electronic Presscontrol starts and stops the pump on demand, maintaining consistent pressure at the tap without the need for a pressure tank, making the system compact, efficient and easy to install.

Built from 304 grade stainless steel with a special corrosion-resistant coating, the CBI pump range is engineered for long service life in clean water applications, including potable water supply. Each unit is supplied with a brass suction line check valve and a high-quality mechanical shaft seal to protect the pump, minimise leakage and ensure dependable operation day after day. Simple access to key components also makes these pumps easy to repair, service and maintain over their lifetime.

Southern Cross CBI pumps are ideal for domestic water supply, rainwater harvesting, rural and stock watering, wash down, pressure boosting and heating or cooling circulation systems. For best performance, the pump should be installed as close as possible to the water source on a rigid foundation, under a weather-proof, well-ventilated cover, with adequate drainage in case of leakage—especially for indoor installations. CBI-2 models feature 25mm (1" BSPF) ports, while CBI-4 models offer 32mm (1¼" BSPF) x 25mm (1" BSPF) connections, giving you flexibility to match your existing pipework.
