The Southern Cross CBI 4-40PT8 is a high-flow stainless steel multistage pressure system supplied with an 18L pressure tank and mechanical pressure switch for automatic domestic and rural water supply.
Built on the 4-Series high-capacity platform, the 4-stage CBI 4-40 pump delivers significantly stronger flow performance than the 2-Series models while providing reliable pressure output for multi-outlet systems. The included 18L pressure tank reduces pump cycling, improves pressure stability and enhances system longevity.
Manufactured entirely from 304 stainless steel with a SiC/Carbon mechanical seal and TEFC motor, the CBI 4-40PT8 is engineered for corrosion resistance, durability and dependable long-term performance.
Ideal for larger homes, irrigation systems and rural pressure boosting applications requiring higher flow capacity.
