## Questions & Answers

**Q: Wha'ts the minimum RPM and max RPM?   what's the rotation direction ? Can you gravity feed this pump ?**
A: 1st question "What is the minimum and maximum RPM?"Minimum RPM is 1000 (The pump would get inadequate lubrication in the crankcase area if it's turning to slow)Maximum RPM is 3400 (The S34 in the pump part number stands for Solid shaft, 3400 RPM)2nd question "what's the rotation direction?"This pump can turn either clockwise OR counter-clockwise, as long as the RPM does drop below the minimum.3rd question "Can you gravity feed this pump?"Yes.  For best results the pump should be placed or mounted BELOW the tank that feeds it with water.  Try to eliminate any elbows or tees in the inlet plumbing that would create turbulent flow, and cavitating the pump.

**Q: what is the size of the input shaft?**
A: The shaft diameter is 0.945 inches. (24mm)

**Q: Can I use this pump with an electric motor**
A: This pump has a solid shaft out the side of the pumps onto which is normally placed a pulley to run a belt to either a gas engine or electric motor.  The pump runs at 3,400RPM so can run with a standard gas engine at 3,400RPM or an electric motor that runs at 3,400RPM.  It is a 24mm shaft and needs at least a 13Hp Gas engine, or 10Hp Electric motor.

**Q: Wat size pulley on motor and pump**
A: It would depend on the motor you are using with the pump.  You would need to determine the GPM and RPM you want.  For a gas motor that runs at 3400 RPM you would need a 1:1 ratio.  If you are using an electric motor that runs at 1750 RPM you would need a 2:1 ratio.  There is a formula that would need to be figured to determine the size pulley.
