Product Introduction：
The TH20B is a spring adaptive type peristaltic pump head,widely used in the medical area, such as in hemodialysis, intraoperative irrigation, in vitro diagnostics (IVD), and biosample delivery etc..
It features a built-in self-adaptive spring roller assembly paired with a manual tube clamping lever, enabling quick installation and removal of medical tubing without tools. The spring buffer structure automatically balances tube squeezing pressure to prevent tubing rupture caused by overpressure, significantly reducing wear on medical silicone tubing and dialysis PVC tubing, extending lifespan of consumables and lowering overall maintenance costs of equipments for medical institutions.
Compatible with DC motor,stepper motor and servo motor, Embedded panel mounting, desktop complete machine assembly, adaptable to various medical equipment structures.also supports ODM/OEM customized development.
