Kewl!They are called diaphragm or metering pumps. They use the same tubing as RO units. We use them for treating our domestic water. We pump a silicate through the system that coats the pipes. Helps prevent pin holes in copper piping. I've seen one shoot water ten feet without a pipe. One of my techs gave it to me to use as a dosing pump, but it's too loud for my living room. They work by a diaphragm being moved by a magnetic solenoid. The solenoid makes a pretty loud thumping noise.

Yes.How do you plan to use the P4 for AWC? Just with level sensors in the sump and one pump to drain and one pump to fill?
The P4 (and P3) has the ATO/AWC programming built in.
On start, the ATO function is disabled.
The drain pump kicks on and drains until the lower level sensor is activated.
That pump turns off and the fill pump is turned on.
The fill pump turns off when the upper level sensor (which is also the ATO sensor) is activated.
ATO functionality is then restored.
So you've automatically pumped in the exact same amount of water that you removed.
