Seal aging or inadequate lubrication‌
Long-term use causes seals to harden and lose sealing effectiveness. Insufficient lubrication increases internal friction, leading to uneven operation and slippage.

Roller wear or deformation‌
Prolonged compression of tubing causes roller surface wear or deformation, resulting in insufficient or uneven pressure. Worn rollers cannot effectively compress tubing, causing pump slippage.

Tubing wear or aging‌
Long-term use reduces tubing elasticity, increases inner diameter, or causes local. Aged tubing cannot withstand normal pressure, leading to abnormal operation.

Improper installation‌
Incorrectly secured tubing or uneven roller gaps (parallelism error >0.1mm) causes uneven force distribution, resulting in slippage.

Drive system failure‌
Motor or reducer failures may cause unstable pump speed, indirectly leading to slippage issues.

Solutions for peristaltic pump head slippage
Replace worn components‌

Regularly inspect and replace aged seals (recommended every 6-12 months)
Replace worn or deformed rollers, ensuring smooth surfaces
Promptly replace aged tubing (silicone tubing: ~1000 hours; rubber tubing: ~500 hours)
Proper lubrication maintenance‌

Use appropriate lubricants for smooth operation
Add specialized lubricant to rotor bearings every 3-6 months
Correct installation adjustment‌

Re-secure tubing, ensuring roller parallelism error <0.1mm
Check and tighten all loose components to reduce vibration
Regular maintenance checks‌

Weekly tubing inspection for cracks, bubbles, or hardening
Monthly motor status checks (shutdown required if >60°C)
Establish preventive maintenance with replacement reminders
Technical improvement solutions‌

Use tapered stainless steel rollers for increased friction
Consider auto-adjusting pump heads with adjustable roller distances
Preventive measures
Use high-quality components‌

Select high-elasticity silicone or fluor rubber tubing
Choose corrosion-resistant seal materials (Viton or EPDM)
Optimize operating parameters‌

Avoid prolonged high-load operation
Adjust speed and pressure based on medium characteristics
Establish maintenance system‌

Implement detailed maintenance plans
Record usage time and maintenance history for tracking
