- Commodity name: PDP Series
- 产品系列: Micro Piston Pump
Widely applied in single‑fluid aspiration and dispensing applications.

Micro plunger pumps are widely used in single-fluid aspiration and dispensing applications. They deliver class-leading performance, ensuring high precision and accuracy in pipetting, dilution, and dispensing operations, with exceptional performance in low-volume liquid handling. Their ultra-low maintenance design provides superior process safety and peace of mind for even the most challenging applications. Featuring a compact structure and offering a wide selection of fluid path materials, these plunger pumps are built with a modular component design that enables flexible configuration and easy integration. They can be directly incorporated into systems such as biomedical analytical instruments, high-precision sampling equipment, and environmental monitoring devices.

Special Features
● High precision：world-leading liquid processing，excellent accuracy/precision for low volume.
● Wide application：can be used in any fluidic application.s
● Long lifespan：long lifespan and enduring, requires little to none maintenance.
● Many Optional Components：depends on the customers’needs, the pump head could use either PEEK or Acrylic, the piston can be made in PEEK or SS316L (100μL and 250μL can only use SS316L). We provide encoder, three-way valve and other optional configurations.
