Peristaltic pumps are known for their simplicity, reliability, and ability to handle corrosive or viscous fluids without contamination. However, like any industrial equipment, improper maintenance can significantly reduce their lifespan and performance. Avoiding common mistakes can help you get the most out of your investment and minimize downtime. Here are some of the most frequent maintenance errors users make—and how to prevent them.
Tubing is the heart of a peristaltic pump. Over time, it naturally degrades due to compression cycles. Many users wait until a visible leak occurs before replacing the tubing, which can lead to system contamination, pump damage, or unexpected downtime. Instead, establish a preventive replacement schedule based on operating hours or cycle count.
Not all tubing is suitable for every fluid. Using tubing that reacts with the chemical being pumped can lead to swelling, cracking, or premature failure. Always match the tubing material (e.g., silicone, Norprene, Viton) with the chemical compatibility of your application.
Peristaltic pumps can run dry without damage—but not indefinitely. Running dry for too long can cause excessive heat buildup in the rotor and tubing area, leading to premature wear or failure. Whenever possible, monitor flow conditions and avoid excessive dry runs.
Many users mistakenly tighten the rollers or tube retainers too much in an attempt to increase pressure or flow rate. This only causes unnecessary strain on the tubing and motor, accelerating wear and reducing efficiency. Follow the manufacturer’s torque specifications for optimal performance.
While many tube pumps are dry-running, larger hose-type peristaltic pumps often require internal lubrication to reduce friction and heat. Neglecting this step can lead to overheating and hose failure. Always use the recommended lubricant and follow scheduled maintenance guidelines.
Over time, flow rates can drift due to tubing fatigue or pump speed variations. Failing to periodically check and recalibrate your system can result in inaccurate dosing or underperformance, especially in critical applications like chemical metering.
Extreme temperatures, UV exposure, or exposure to ozone can degrade tubing faster than expected. Be sure to use protective enclosures or choose tubing materials designed for harsh environments if needed.
Peristaltic pumps are low-maintenance by design, but they still require informed care to perform at their best. By avoiding these common mistakes, you can extend the life of your pump, reduce maintenance costs, and ensure reliable operation in demanding industrial environments.
