The Pump Shed Australia
The Franklin AquaDuty CPS75 is an intelligent variable-speed pressure pump designed to maintain steady water pressure as demand changes. It automatically adjusts its speed when taps, showers or sprinklers are turned on, providing consistent pressure while reducing noise, power consumption and pump cycling.
Ideal for domestic water supply, rainwater tanks, household pressure boosting and light irrigation systems. Available as the CPS75 pump only or the ADCPS75 complete package with an 8-litre pressure tank.
