DP-3000 Series Linear Pump

nnnn

Linear Pump Technology for High-Volume Production

nnnn

Features and Benefits

nnnn

■ Rapid refill speed for optimal underfill

nnnn

dispensing

nnnn

* Quick-release mechanisms of wetted parts

nnnn

for easy setup and removal from the system

nnnn

■ Tool-free disassembly and assembly for

nnnn

quick and easy cleaning

nnnn

■ Better than 1% 3-sigma accuracy for

nnnn

consistent dispensing with multiple

nnnn

programmable shot sizes

nnnn

* Fast, efficient priming with minimal material

nnnn

waste

nnnn

■ High flow rate for high throughput

nnnn

■ True positive, displacement dispensing,

nnnn

independent of viscosity

nnnn

■ Outperforms rotary positive displacement

nnnn

pumps with regard to accuracy, speed, and

nnnn

wear
