Thanks....makes perfect sense!

I am reviewing a document for a duplex submersible sewage lift station and it makes reference to a modified pump head capacity curve where the friction losses in the suction and discharge piping of the individual pumps are omitted from the system head-capacity curve. It says "instead, these...

I would normally use SS, but the contractor has an abundance of carbon steel piping and was wondering if he could use it instead. If I were to use SS, it would be sch 10 as well so using sch 10 CS would not require any additional supports than what is already budgeted/planned.

I'm running a pipeline from blowers with a discharge pressure of 10 psig to an aerated cell roughly 30 ft away. I intend on using carbon steel pipe, but wondering about the schedule. Can schedule 10 CS piping be used?

zdas04: No, submersibles are not an option. The tank interior is comprised of biological membrane cartridges. Snorgy: The pipe diameters range from 5" SS to 2.5" SS. The fluid is a treated wastewater so basically water. See my response to zdas04. The design is based on particular...

Snorgy: Thanks, but unfortunately, stuck with the system piping as is, so no wall penetrations can be done. I know it is not ideal, but its what has been thrown at me to make work, so hence my question.

Thanks. I've already allowed for a priming system to aid the priming process. Also have a copy of the "Pump Handbook" right here.

Thanks. I own a couple of different versions of Cameron's but it does not get into that particular level of detail on how to handle my application.

We have a piping situation that is not ideal, but can't be avoided. We have a tank with roughly 10 feet of liquid which can drain down to roughly 1 ft of liquid. A vertical pipe draws liquid out of this tank, up and over the wall of the tank and back down the other side to a self priming pump...
