Common Questions
Have More Questions? Our technical team is ready to provide detailed, personalized guidance.
Q1: How long do reinforced polypropylene filter plates typically last?
Under normal operating conditions, these plates have a service life of 3-5 years. However, this can vary based on operating pressure, chemical exposure, temperature conditions, and maintenance practices.
Q2: Can reinforced polypropylene filter plates withstand high temperatures?
Standard reinforced polypropylene plates can operate reliably up to 80°C. For higher temperature applications up to 95°C, specially formulated high-temperature grades are available.
Q3: How do I know when filter plates need replacement?
Signs that indicate replacement may be necessary include visible cracks or deformation, decreased filtration efficiency, inconsistent cake formation, and leakage between plates during operation.
Q4: Can reinforced polypropylene filter plates handle abrasive materials?
Yes, the glass fiber reinforcement significantly improves abrasion resistance compared to standard polypropylene plates, making them suitable for moderately abrasive slurries.
Q5: Customization Options
Our engineering team can develop custom solutions to meet your specific filtration requirements:
- Custom sizes to fit existing filter press equipment
- Specialized port configurations for unique process flows
