1.6 Gear Ratio Assembly

PULSAR Shadow
® pumps are driven by a standard C-face electric motor mounted on the motor
adaptor input flange. The motor drives a set of worm gears, which convert rotational speed into
torque. They, in turn, power the eccentric shaft assembly that converts rotary motion into
reciprocating motion. The drive motor can be wired to rotate in either direction.
More than one pump can be driven through
a single drive assembly. This is referred to
as multiplexing. The pumps are mounted to
a common gearbox assembly, and driven
by a common motor. Each pump is
mounted on a standard simplex base.
Whenever pumps are multiplexed, the
eccentric shafts are positioned to place a
uniform load on the driver. Before full
disassembly, always note the relative
positions of the eccentric shafts to each
other so they can be reassembled back in
the same orientation.
