OK this has been a long works in progress project.....got it to a point now to show and tell. The regen pump and plumbing done. Still have to do the plenum and hook-up.
The pump is 2.2 KW (about 2.2Hp) single phase. I don't have 3 phase hence this was the largest pump I could get on single phase. It's hooked up to its own breaker and I'm using a contactor (relay) so a small toggle switch can be used to turn it on and off.
The pump has a silencer attached giving a max 70 db noise level when standing at my usual spot.
The plumbing includes a relief valve with its own filter and a main inline filter that has a lid that can be easily opened and filter replaced.
Being a sceptic with the power of my 2Hp pump being sufficient I have zoned my 4 x 4 table into 4 zones......with 4 valves that can be opened and closed individually. Each zone has its own vent valve as well to release vacuum so as to avoid turning off the pump between reloading the table.
I have tested the system (by closing the 4 zone valves) and the vac gauge shows 5" hg when the relief valve kicks in maintaining this pressure.
Below pics showing so far.....more to follow.
