The Pump 120 PSI (part# AQ120) is a genuine Tacony OEM replacement part from the chassis assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the solution pump that pressurises cleaning solution from the tank and delivers it to the spray jets.
What the Pump 120 PSI does
Everything the machine does at the carpet starts here. The pump takes solution from the tank and holds it at a set pressure so each jet produces the spray pattern the wand was designed around. Pressure is what determines whether solution is atomised into the fibre or merely poured onto it, so a pump that has drifted low does not stop the machine, it just quietly makes every pass less effective while the operator wonders why the carpet is taking longer to dry.
When to replace the Pump 120 PSI (AQ120)
Replace it when pressure is low or will not build, when output pulses badly, when it runs but moves nothing, or when it has become noisy or is cycling constantly. Before condemning it, rule out a blocked filter, an air leak on the suction side, and a partly closed valve, since all three imitate a failing pump.
Pump PSI AQ120 — fitment and installation notes
Never run it dry, even briefly, because the seals depend on the fluid for cooling and lubrication. Prime it properly on first start, keep the inlet filter clean, and flush the system with clear water at the end of a job so cleaning chemistry is not left sitting in the pump between uses. Tacony builds the Tornado Marathon SE 900 and the Powr-Flite Prowler PFX900S on a single machine platform, so this component carries across both brands rather than belonging to either one. It is a shared Tacony component and may fit additional models beyond those listed — call us and we will confirm against your serial number.
