How much pis can a 8hp motor push?

The amount of pounds per square inch (psi) that an 8 horsepower (hp) motor can generate depends on various factors, including the type of pump being used and its efficiency. Generally, an 8 hp motor can produce a significant flow rate, but the specific psi output will vary based on the pump design (centrifugal, positive displacement, etc.) and the system it operates in. Typically, you would need to refer to the pump's specifications to determine the exact psi it can achieve.
