These are the wearing parts for Aqua Master Tools C Series dosing pumps. Each one is designed to be swapped in a few minutes, so a worn part doesn't mean a new pump unit.
In a peristaltic pump, rollers squeeze the inner tube with every turn. Over time the tube loses its spring and each turn moves slightly less liquid, so doses shrink without any warning. The tube is rated for 1,000 hours of running. If a timed test run into a measuring jug comes up short, the tube is usually the cause.
Replacement pump cassette. A complete, pre-assembled pump: motor, inner tube, tube guide and front housing. It fits any pump position on a C10, C20 or C30. Undo the two front screws, lift the old cassette out and reconnect the red and black wires exactly as they were on the original. The motor is rated for 800 hours of running, and this is the part that replaces it.
Inner pump tube with connectors. The tube inside the pump head, made from Pharmed BPT. It's food-grade, flexible and rated for phosphoric acid up to 85%, nitric acid up to 35%, citric acid up to 20%, and concentrated potassium hydroxide and potassium carbonate. Flush the line with clean water and empty it before replacing.
PTFE dosing tube, 5m. The tube that runs from your bottles to the pump and from the pump to the tank. It's 4mm internal, 6mm external, food-grade and resistant to concentrated acids and alkalis. Each pump comes with 3m. The 5m length gives you room for longer runs or a full change of line.
These parts fit Aqua Master Tools C Series pumps only.
