680SD Brushless Servo Pump

Overview

Introduction This manual describes how to install, operate and maintain the 680SD Brushless

Servo Pump. The CAMALOT 680 SD Servo Driven Brushless pump is a liquid/semi

liquid, precision dispensing device. It is typically used for encapsulation and underfill

operations. The pump is comprised of servo driven brushless motor, a rotary

leadscrew and cartridge assembly, main body housing with a Luer fitting to except

dispense material syringes.

Theory of Operation Dispensing of material is accomplished by using air pressure to provide a constant

supply of material to the leadscrew. Air pressure is also applied to an integral air

cylinder to raise the leadscrew and open the dispense port, thereby allowing the flow

of material through the needle.

Servo control is used to provide a means of varying the speed of the pump motor. The

motor RPM is programmable and turns on and off under program control. It does not

run continuously.

Control of dispense drip or leaking while the leadscrew is not turning is accomplished

by removing air pressure from the integral cylinder and allowing the leadscrew which

has a machined ball on the end to return from the dispense position, sealing off the

reservoir end of the needle.
