Fine Tuning Lift Height

Fine Tuning Lift Height
Introduction If material flow through the pump is either insufficient or excessive after purging, you
will need to adjust the lift height in order to achieve the correct volume of material.
Procedure Adjust the lift height as follows:
1. While selecting the Purge On button, rotate the adjustment ring clockwise (to
decrease volume) or counter-clockwise (to increase volume) until satisfactory
flow is achieved.
2. When the desired volume is achieved, rotate the adjustment an additional ½ turn
and then back to the desired setting to eliminate any backlash.
3. Tighten the lock screw.

Description
Attention
Needles that are used on the 680SD pump are not interchangeable with needles
used on other pumps. The leadscrew ball seats in the needle to shut off material flow
and establishes the lift height (ZERO). Damage to the leadscrew will result if the
proper needles are not used.
The pump is designed to be used with unique stainless-steel needles. A variety of
needle sizes are supplied with the pump.
