I do not know what you mean by cycle. A booster pump should keep a constant pressure on
the RO membrane. Cycling would be self-defeating, for if the pressure changes, do to a
on-off phase, there would be a continuous pressure difference on the membrane.

Or are you talking about a RO container pressure pump, that keeps made RO water in a
container at x pressure to pump to y place.

For the Kent unit, just go to their website and e-mail them.

If You See Me Running You Better Catch-Up
