MR02 Manual Resin Recovery Pump Instructions: The manual resin recovery pump must be cleaned after use! You can clean it directly with alcohol. For water-washed resin, you can directly use tap water to clean it. This prevents corrosion and excess resin from solidifying, which can affect secondary use. The black duckbill can also corrode slightly if not cleaned. Furthermore, if not cleaned, solidified resin can affect reusability. Therefore, cleaning after use is essential! Based on extensive customer feedback from our first-generation product, we have introduced the second-generation manual MR02 and the third-generation industrial-grade electric peristaltic pump, the ER03, to address issues such as resin viscosity, corrosion, suction power for various liquid resins, corrosion, speed regulation, filtration, and cleaning. Please choose the right pump based on your specific needs. For frequent use, the third-generation electric ER03 is generally recommended.
