A: Yes, our ceramic plunger pump systems handle particle-loaded formulations including PLLA and similar microsphere products. For detailed technical discussion, please leave your contact information and our engineering team will get in touch.

The standard ceramic plunger pump configuration reliably handles up to 80,000 mPa·s (e.g., HA gels, collagen, PLLA suspensions). For ultra-high-viscosity formulations in the 100,000–1,000,000 mPa·s class — such as paste-grade dermal filler bases, high-solids hydrogel precursors, and dental or resin pastes — we have successfully run trials and customer samples at approximately 1,000,000 mPa·s. At this viscosity level the product behaves as a thixotropic semi-solid rather than a free-flowing liquid; throughput decreases accordingly, and we always recommend sample validation with your actual formulation.
