Watson Marlow Qdos 60 Pump
Spare Parts for Qdos 60 Pump
Product Summary
The Watson Marlow Qdos 60 is a high-accuracy chemical metering pump featuring the patented ReNu pumphead technology for tool-free maintenance. Delivering flow rates from 0.1 to 1000 ml/min at pressures up to 7 bar, it offers a superior alternative to diaphragm pumps by eliminating gas-locking and valve clogging. Its contained pumphead design ensures operator safety by preventing chemical exposure during maintenance.
- ReNu Pumphead Technology: Fully sealed, single-component pumphead allows for quick, tool-free replacement in seconds, minimizing process downtime.
- High Turn-Down Ratio: Offers a 10,000:1 flow control range (0.1-1000 ml/min) with ±1% accuracy for precise chemical dosing.
- Valveless Design: Peristaltic action eliminates ancillaries like backpressure valves, degassing valves, and foot valves, reducing installation costs.
- Fluid Recovery: Integral leak detection and fluid recovery system protect operators from chemical exposure and reduce waste.
- Versatile Control: Available with Manual, Analog (4-20mA), Contact, or PROFIBUS control options for seamless system integration.

Troubleshooting, Common Faults & Solutions
Pump displays 'Pumphead failure'
Likely Cause: Leak detected within the ReNu pumphead or head not fitted correctly.
Action / Part: Perform fluid recovery sequence and replace ReNu Pumphead (0M3.3200.PFP).
Motor stall or 'Over current' error
Likely Cause: Excessive discharge pressure or blockage in the line.
Action / Part: Clear discharge line blockage and check system pressure.
No flow displayed
Likely Cause: Pump in wrong mode (e.g. Remote stopped) or suction issue.
Action / Part: Check control mode and suction line for air leaks.
Inaccurate flow
Likely Cause: Viscosity change, suction lift too high, or uncalibrated pump.
Action / Part: Perform flow calibration via the HMI menu.
Screen blank or frozen
Likely Cause: Power supply interruption or drive fault.
Action / Part: Cycle power to the drive. If persistent, replace drive unit.

Watson-Marlow Qdos 60 spare parts: frequently asked questions
Tap a question to see the answer.
What spare parts are listed for the Watson-Marlow Qdos 60?
The list covers ReNu 60 pumpheads in three versions (7 bar Santoprene, 4 bar SEBS and 5 bar polyurethane), interface tubing in PVC and polyethylene sizes, the HMI protective cover and the I/O control cable.
How is the Qdos 60 pumphead replaced?
The Qdos 60 uses a fully sealed ReNu pumphead that is replaced as a single unit, quickly and without tools. If the pump shows a 'Pumphead failure' alarm, the troubleshooting guide says to run the fluid recovery sequence and fit a new ReNu pumphead.
Which ReNu pumphead do I need?
It depends on the pressure your system needs and the chemical being dosed. The 7 bar Santoprene, 4 bar SEBS and 5 bar polyurethane heads are all listed. Tell us your fluid and pressure on the quote form and we'll confirm the match.
How do I make sure I order the right Qdos parts?
Tick the parts you need and your selection carries into the quote form, with a nameplate photo if you're unsure. Running a smaller unit? See the Qdos 20 and Qdos 30 pages, or all Watson-Marlow spare parts.
