Hospital Hemodialysis & CRRT Machines — Dialysate/Blood Circuit
Precision Micro Gear Pumps for Hemodialysis, CRRT & Dialysate Proportioning
Zero-leaching pulse-free dialysate A/B proportioning & thermal chemical disinfection for hospital hemodialysis machines and bedside CRRT — engineered for 80°C citric acid / peracetic acid flushing, biocoMPatible non-extractable materials, and 4 MPa silent bedside clinical operation.
Drawbacks of Conventional Pumps in Hemodialysis & CRRT Loops
Pumps currently integrated into hospital hemodialysis machinery and CRRT bedside systems suffer from critical failure modes that directly trigger conductivity & pH alarms, contaminate medical fluids with metal debris, and fail strict medical-device biocoMPatibility audits.
Three Medical-Grade Technological Breakthroughs & Customer Feedback
JONSN's solid technical advantages for hospital hemodialysis & CRRT come from a fully redesigned material stack (UK Victrex pure wear-resistant PEEK + 100% high-purity Zirconia nano-ceramic shafts) and a fully integrated unblinded two-stage housing with magnetic-driven static seal, validated by an authentic 14-month field testimonial from a global medical supplier.

Engineering Q&A
How does JONSN micro gear pumps ensure online dialysate dilution precision in hemodialysis machines?
Traditional peristaltic pumps rely on roller extrusion, generating severe volumetric pulses that cause concentration alarms. JONSN provides an absolute pulse-free positive displacement constant delivery, seamlessly mixing A/B concentrates with RO water under a verified linear reproducibility, keeping machine conductivity and pH levels rigidly uniform.
Are JONSN medical-grade pumps chemical-resistant to high-temperature thermal sanitization and aggressive disinfectants?
Yes. As calibrated in our technical datasheets, JONSN non-standard custom pumps safely withstand 85°C chemical rinsing and hot water sanitization. Molded with premium wear-resistant PEEK from UK Victrex and Zirconia ceramic shafts, the fluid paths withstand continuous peracetic acid or citric acid flushing without localized leakage.
How does JONSN lock whisper-quiet low noise performance for bedside intensive medical environments?
Abandoning old multi-segment shapes and standard carbon-fiber bearings, JONSN utilizes a two-stage shell design with a Magnetically driven static seal. Clearance tolerances are rigidly locked by Mazak multi-axis machining centers to eliminate mechanical running runout and friction vibrations, securing whisper-quiet operations below strict clinical baselines.
Does JONSN offer ISO 13485 compliant biocoMPatibility alignment for custom embedded dialysis fluid blocks?
Yes. Operating under strict TÜV Rheinland ISO 13485:2016 compliance, JONSN uses 100% Zirconia structural ceramics and medical PEEK to eliminate any dynamic seal friction residue or heavy metal extractables. Technical leaders can request our 2D blueprints and CAD STEP models to execute seamless embedded space layout alignment within 24 hours.
