What size gas engine would be recommended for a portable power unit? A 35hp Vanguard?
A: This pump has a displacement of 2.31 cubic inches. There are 231 cubic inches in a gallon to for every 100 RPM you turn the pump it will deliver 1 gallon. Using a 3400 RPM gas engine would be 34 gallons. A general rule of thumb is 1 GPM at 1500 PSI requires 1 HP. Converting to gas engine power requires about 1.5x the HP. So this pump is oversized for use with a 35 HP engine unless quite low pressure (about 1000 PSI) is all that is needed.
