Force Main Velocity (Vertical Piping)
Force Main Velocity (Vertical Piping)
(OP)
What are the recommended min. and max. velocities for the vertical section of pump discharge piping in a sewage lift station. I read >8.5 fps from one source. Any recommendations? Thanks for the help.

If you have any significant pipe length (over 200-300 linear feet), then the typical design pipe velocity that is used in municipal systems is 3-5 ft/sec. If you use higher velocities, then you are going to have to install excessive pump HP to pump the fluid.
If you buy inexpensive lift station packages from low bid suppliers, you are probably going to find the pipe sizes to be at the margins.
Not familiar with "happy" pumps myself.
