I am trying to design a simple pumping system to transfer water over a 10' high wall that divides two basins. I want to use a 7.5HP submersible pump for this application. Design flow will be ~1-1.3 MGD. Static head will vary between 2 and 7 ft. In order to create sufficient TDH, I considered...
I have a portable submersible solids handling pump mounted on a self-supporting stand in a large open pond. The pump curve shows BEP to be 1500 GPM @ 29 FT TDH. The pump curve ends at ~2500/10. The pump is operating just beyond BEP at ~1700 GPM @ 26 FT TDH. This pump has an 8" discharge and...
Does anybody have experience with a VAPEX hydroxyl fog odor control system? Rather than drawing air from source and treating it, the Vapex system fogs the wetwell (or manhole, whatever) with a hydroxyl fog. Curious if the "hydroxy" will attack anything.
What are the drawbacks of using FRP (plastic) piping within a submersible sewage pump station. Most U.S. municipalities that I work with standardize on ductile iron piping within a pump station. Plastic piping is commonly used in Canada, with excellent results. I am wondering if anybody can...
I'm looking for expert opinions on recommended seal face materials for sewage pumps (pros/cons).
Tungsten-carbide vs. Tungsten-carbide or silicon-carbide vs. silicon carbide
Has anybody experienced a drive "going plasma?" I was at an equipment startup recently and a brand new 200 HP drive toasted after ~20 minutes of operation. The drive rep. said it "went plasma." It was very fortunate that the panel door was closed. Minutes earlier...
