Pumps, Wells, Tanks, Controls / newly installed CSV question

« on: June 16, 2016, 08:06:19 AM »

Just installed csv1a on my hydropneumatic system. (60 gal galvanized tank, 1hp Goulds 10ls10 submersible with Franklin motor set at 157 feet, 95 ft water table, 32psi cut on/52psi cut off, CSV set to 40psi.). The pressure on inlet of CSV varies from 80 to 133psi, depending in tank pressure.  Is there any concerns for damage to this particular pump as far as impeller damage, cavitations?  The CSV works perfectly, but I don't want to damage the pump.  I've read some particular pumps don't work well with csv.

Pumps, Wells, Tanks, Controls / Air volume in hydropneumatic system.

From my previous question I learned that my air over water system needs the check valve with incorporated snifter valve at the tank, and the bleeder valve down well.  Now I need to find out if, with the CSV, does the amount of air in the tank have as much importance.  I will still get some air supplied with each pump start, but with less starts, the tank may end up with more water than usual.  I would like to avoid having to pull the supply line out of the casing to lower the bleeder valve if it isnt necessary.

Thank you for your quick reply.  I really appreciate your knowledge and willingness to help educate those of us willing to learn.  There should be more folks like you in the world.

Pumps, Wells, Tanks, Controls / Check valve between CSV and tank

« on: June 03, 2016, 01:51:02 PM »

My air over water tank has a one way check valve with incorporated Schrader needle valve  just prior to pressure switch and before line enters tank.  If I install CSV at top of casing, do I leave the check valve in place?  I know there is a bleeder down well a few feet, and a check valve at submersible 1hp pump.  There is an air regulator at midpoint of tank to release excess air.  Thanks for any help.
