I'm glad it worked well for as mine has worked for me.
The 2088-422-444 is identical to the 2088-422-144 pump I
bought. Although in Australia they sell for AUD$140
(USD$88). The heatsink was not available but I'm going to
worry about that later if heat rise is a problem.
Select your nozzles so you get about 2.0 bar pressure out of
the pump. That way you will get good impact from the spray,
yet the pressure is not too high for the pump to overwork.
You did not specify the pressure you ran the test at. These
diaphragm pumps increase current consumption directly with
pressure. What was the voltage and current during your test ?
