2.1Reagent Head Assembly

The typical reagent head assembly consists of reagent head, diaphragm, and suction and discharge cartridge check valves. This assembly is the only part of the pump to contact the process liquid; consequently, maintenance is critical to pump performance.

2.2Control Assembly

The OMNI® pump incorporates a lost motion style of stroke length adjustment to limit diaphragm travel during the suction portion of each stroke. The stroke length setting is indicated by a (0% – 100%) scale located on the stroke adjustment assembly.

Stroke length is changed by loosening the locking screw and turning the hand knob. This turns a mechanism, which limits rearward travel of the diaphragm. Refer to Section 6.2 for further information.

For automatic flow rate control, users can consider the Pulsafeeder MPC speed based control system, please contact your local Pulsafeeder dealer or representative for more information.

2.3Gear Ratio Assembly

OMNI® pumps are driven by an electric motor mounted on the motor adaptor input flange. The motor drives a set of worm gears that convert rotational speed into torque. They, in turn, power the eccentric shaft assembly that converts rotary motion into reciprocating motion.
