Gear Reducer Assembly
PulsaPro 900
pumps are driven by a standard C-face electric motor mounted to an
adaptor that completely encloses a coupling. The motor drives a worm gear reduction that
turns an eccentric shaft assembly – converting the rotary motion into reciprocating motion.
Figure 6
A single drive assembly can drive up to four Pump/Reagent Head assemblies. This is
referred to as multiplexing.
Figure 7
Whenever pumps are multiplexed the eccentric shafts are positioned to place a uniform load
on the drive. 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.
