When purchasing a roller pump (also known as a peristaltic pump), the guarantee or warranty depends on the manufacturer, application, and operating conditions. Here’s what you should know:
Standard Warranty Period
Most industrial roller pumps come with a 1 to 2-year warranty.
Medical-grade pumps (e.g., for dialysis) may have longer warranties (2–5 years).
What’s Covered?
Manufacturing defects (e.g., faulty motor, rotor, or housing).
Premature wear under normal operating conditions.
What’s NOT Covered?
Wear parts (e.g., tubing, seals) – These are considered consumables.
Misuse (overloading, running dry, incorrect tubing installation).
Chemical incompatibility (using the wrong tubing material for aggressive fluids).
Extended Warranties
Some manufacturers offer extended warranties (3+ years) for an additional cost.
✔ Use OEM (Original Equipment Manufacturer) tubing & parts – Third-party tubing may void the warranty.
✔ Follow maintenance guidelines – Regular inspections, lubrication (if required).
✔ Avoid dry running – Can damage rollers and tubing.
✔ Correct installation – Misalignment can cause excessive wear.
| Brand | Standard Warranty | Notes |
|---|---|---|
| Watson-Marlow | 2 years | High-end peristaltic pumps, medical & industrial. |
| Cole-Parmer | 1–2 years | Lab & chemical handling pumps. |
| Verderflex | 2 years | Industrial-grade roller pumps. |
| Flowrox | 1 year (extendable) | Heavy-duty mining & slurry pumps. |
Motor failure (unexpected shutdown, burning smell).
Bearing/roller failure (unusual noise, jamming).
Leakage from pump housing (not caused by tubing).
⚠ Always check the manual – Some warranties require registration within 30 days of purchase.
Aftermarket repair services (often cheaper than OEM).
Upgrading to a more durable model (e.g., reinforced rollers for abrasive fluids).
