Key Specifications & Applications
- Underwater pelletizing systems (MAAG®, BKG® compatible)
- Strand pelletizing lines for engineering plastics and compounds
- High-output production lines requiring minimal blade change frequency
- Custom blade geometry available for non-standard pelletizing systems
Why Customers Switch to SZSUNLIT Pelletizing Knives
- Dimensional accuracy engineered to OEM tolerances — drop-in compatible
- Material selection optimized for wear resistance in high-throughput lines
- Trusted by major polymer compounders and petrochemical processors in China
- Significant cost reduction versus OEM replacement blades
Mini Magnetic Drive Pumps — Precision Sealless Design for Chemical & Industrial Use
Compact magnetic drive pumps engineered for safe and reliable transfer of corrosive, hazardous, or high-purity fluids. Built to international precision standards, our pumps deliver equivalent performance to leading global brands at a lower total cost of ownership — ideal for OEMs, laboratory equipment manufacturers, and industrial system integrators. Our pumps are suitable for long-term, low-maintenance operation.
Applications:
- Chemical dosing and corrosive fluid transfer
- Laboratory and analytical instrument fluid circuits
- Precision fluid handling in semiconductor and coating equipment
- High-pressure or high-viscosity fluid systems requiring leak-free operation
- New energy battery manufacturing: separator coating and precursor metering systems
- Cooling systems for radar, servers, and EV fast-charging stations
- Aerospace cooling and thermal circulation systems
Why Customers Switch to SZSUNLIT Magnetic Drive Pumps
- High-pressure capability — sustained operation up to 20 Bar, suitable for demanding fluid systems where standard pumps fall short
- Extreme temperature range — rated from −120°C to +170°C, covering cryogenic, ambient, and high-temperature applications within a single pump series
- Exceptional service life — 40,000+ hours at low pressureand standard operating conditions, significantly outlasting both domestic alternatives and major import brands
- Dry-run tolerance — Capable of withstanding up to 100+ hours of dry operation (application dependent), reducing risk during self-priming and intermittent-use applications
- Lower total cost of ownership — import-grade quality at 60–70% of the cost
