Evap pump
The pump discharge reducer doesn't matter if it's concentric or eccentric. It's the pump SUCTION that needs to be an eccentric reducer that is always flat on top (F.O.T.) The eccentric reducer on the pump suction reduces pump cavatation (pump catching air).
The evap puts moist air in and th AC take moisture out. So you are making the AC work harder
When selecting evap cooler motors for optimal performance and efficiency, key factors to consider include motor size, power efficiency, speed settings, compatibility with the cooler unit, and durability. It is important to choose a motor that is the right size for the cooler, energy-efficient, has adjustable speed settings, fits the cooler unit properly, and is built to last.
Most likely the evap line, there is a fuel out, a fuel in ( recirculate ) and a vacuum ( evap ) line.
