Well pump wont pressurize system

I''m sure not the reason for the pump shutting off, but: For a 30A circuit you should be running 10 ga wire. A 1/2hp pump won''t require 30A though, so I would recommend changing the breaker to a 20A. It''s OK to run wire larger than the breaker rating, but not the reverse. 12 ga wire is rated for 20A max.

On 2021-06-22 by Julie Umecker. A booster pump (Goulds v6P) in a 3.5-story building is cycling on and off frequently and pressure fluctuating between 64 PSI at rest and up to 68-70. We are no aware of any out of the ordinary call for water. And cycling is

Understanding Pump Flow Rate vs. Pressure and Why It Matters

So, when pressure in the pump causes more load on the motor, it slows down. When the motor slows down, the flow rate drops at the same percentage. A motor that operates at about 2000 RPM at low pressures will typically slow down to about 1750 RPM when the pump is pressurized to the maximum rating. It stands to reason, then,
