How Can You Get More Flow Out Of A Gear Pump?

When the shaft spins faster, you get more volume of liquid out of the pump. Standard motor speed designs are 3600 RPM, 1800 RPM, and 900 RPM. But, gear pumps operate at much slower speeds than these standard motor speeds, oftentimes below 800 RPM. But, how do you get more flow in less time from a gear pump? Because let's be honest, time is money!
