Furon PDP precision dispensing pumps utilize cutting-edge technology to deliver extremely accurate doses of media with unprecedented reliability. Furon PDP pumps are designed for long life and are maintenance-free, maximizing the end user's up-time. Our patented PTFE rolling diaphragm technology coupled with precision stepper motor control enables precise dispensing of aggressive or ultra-pure media, eliminating the requirement for expensive flow controllers. The Furon PDP pump features Zero Displacement Valve technology that enables pulsation-free dispensing. Additionally, a fully-programmable suckback valve technology provides complete control over residual drops of liquid, assuring superior recipe accuracy and maximizing chemical efficiency. This pump is a fully-integrated system driven by its own onboard microprocessor. The PDP pump may be operated on its own via the intuitive Graphical User Interface (GUI), or controlled remotely via the built-in RS-485 interface. All wetted surfaces are Fluoroloy-T and Fluoroloy 646 to suit dispensing of ultra-pure chemicals commonly used in the semiconductor industry.
