Pneumatic Sewage Ejectors
Pneumatic Sewage Ejectors
(OP)
Looking for some assistance on manufacturers of pneumatic sewage ejectors.
Don't see too many so I am not familiar with them.
Any help would be appreciated.

Could not find Smith & Lovelace on a search. A local sewage pump rep suggested them. Maybe they changed their name.
Dakota makes the lift stations for exterior use. I might be able to do this but the client has existing pits. It would be difficult to retrofit with a Dakota unit.
I have found information with Yeomans. They seem to be the only ones who have the pneumatic ejectors which can be located inside a building.

It is under the name Smith & Loveless.
Thanks for the help.

Look at my patent pending RamJet.

It seemed pretty impressive.
How would it handle a pair of underwear flushed down the toilet?
RE: Pneumatic Sewage Ejectors
But in any case, the 4" RamJet will pass a 2.5" sphere without clogging. Rags, underwear, etc. pass without clogging. In fact, I used a 4" RamJet for demonstration purposes with very large jet nozzles and an 850 CFM air compressor.
When I would drop a glove into the suction of the RamJet it would throw it about 30 yards away. Also, it does a nice job of shredding the glove if there is any abrasive material.
Can you briefly describe your exact application?
RE: Pneumatic Sewage Ejectors
Flow by gravity fills the pots until appropriate level is reached, then valve opens, compressed air from receiver tank forces the waste out and into either a 6", 8", or 12". Operating time is about 15-30 seconds and time between batches is probably 30 minutes. I am estimating the last value.
Looking at your design, something that pops out at me is that it appears it is suited more for continuous operation. With such a small area of flow, I would be concerned with fouling over time, especially the air intake.
Just a first impression.
RE: Pneumatic Sewage Ejectors
The RamJet can be mounted on top of your tank. It will pull a suction on one tank for quick filling while pressurizing another tank for discharge.
If you only have one tank then it pulls a suction on the tank for quick filling, then immediately pressurizes the same tank for discharge. It uses only two check valves.
It is simple and has no moving parts.
