PistonPRO 4+

NSW PistonPRO 4+ is operated with volumetric valve controls. It is built for high-speed contact dispensing with our efficient fluid control technology. It is easy to set up and fully programmable for mass production processes.

NSW PistonPRO 4+Fluid Pump

R&D Support

Micro-volume dispensing


(Pump conversion)

Low Maintenance &
Worry-Free Design

The PistonPRO4+ is built for speed. Just like a reservoir, we have developed a chamber reservoir management technology that can handle extreme fluid dispensing applications smartly. Instead of drawing directly from its source, this pump has intelligent standby storage, reserving liquid to apply it on the next dispense instantaneously.

Product Highlights

  • Programmable volumetric control via ‘ml’ or ‘µl’ (SI unit)
  • High dispensed volume repeatability, as small as ±0.15 µl or better (tested with pure silicone liquid)
  • Superior fine dispensed volume adjustment, smallest controllable resolution of down to 0.3 nanoliters
  • The dispensed amount is not affected by any material’s viscosity even when changed over time or due to fluctuation caused by incoming air pressures
  • Perfect chamber sealed off design that capacitates ‘non-dripped’ features during mass production
  • High efficient needle with ‘tail-off’ effect via its special ‘suck-back’ function
  • Built-in ‘air remover’ functions to remove trapped air during pump setup
  • Low maintenance cost and less hassle of changing spare parts
  • Easy to operate and fast to learn
