Aquatec variable speed pumps are offered in 3-chamber and 5-chamber models. These pumps allow for constant pressure across multiple outlets via integrated electronic controls. Eliminates the need for pressurized tanks and pressure switches. Our patented 5-chamber diaphragm and piston design allows these pumps to operate at exceptionally quiet noise levels and with minimal pulsations. The smaller, 3-chamber diaphragm pumps offer additional options for space management.
