Micro-volume dispensing


(Pump conversion)

Double the Pump
Twice the Speed

NSW custom design pump head enables various types of fluids to dispense on a workpieces/board at optimal precision with lightning speed.

Product Highlights

  • Programmable volumetric controlled via ‘ml’ or ‘µl’ (SI unit)
  • Repeatable high dispensed volume, up to ±0.15 µl or better (tested with pure silicone liquid)
  • Superior fine dispensed volume adjustment, the smallest controllable resolution is up to 0.3 µl
  • Perfect sealed off chamber design enables its ‘Non-dripped’ feature during mass production
  • Highly efficient controlled release needle that has a ‘Tail-off’ effect via its particular ‘Suck-back’ function
  • 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.
  • Built-in ‘Air Remover’ functions to remove trapped air during pump setup
  • Low maintenance cost & less hassle of changing spare parts
  • Easy to operate & fast to learn
