These are 2nd generation pumps, not ES.
I have 2 MP40s and 1 MP20.
One of the MP40s will need a new power supply and wet sides could use some attention, I switched to Tunze pumps and have not used these pumps in over a year.
I have 2 MP40 Gen1 controllers, 2 Gen2 controllers and one MP20 Gen2 controller, 2 power supplies and 3 wet sides.
$325 shipped for everything.
