Im talking about a 1/25 HP pump motor. 220 volt 50 Hz. Can I run it on 240 volt 60 Hz? Rated for .44 amps.

Likely you can. It will run approx 1/5th faster. One of the features of motors that are affected by hertz is the thickness and composition of the laminations in the rotor andstator cores. Wrong hertz may make the motor a little hotter you will have to monitor this. Of course the motor fan will run a little faster....
Many motors use VSD now so they would be handling similiar hertz from time to time anyway.

For most AC motors, you will need to de-rate the applied voltage magnitude since at a lower applied frequency the magnetic flux in the machine increases which can increase currents in the windings. Some motors are designed for a 50/60Hz range and work fine on both frequencies, but check with the motor nameplate or manufacturer. So, for a machine designed for 60Hz running on a 50Hz system, set the applied voltage to (50/60)*rated_voltage. OR, there are solid-state induction motor drives available that can take single phase AC at 50Hz and convert that to a variable frequency voltage at the output (I think you can vary the voltage magnitude as well). So just adjust the output to 60 Hz. This might be a viable solution, albeit a little costly and there will be some power losses within the drive.

There are several factors that need to be known.
1. The pump will run faster, thereby increasing the flow rate and requiring more power. ------- could be a problem
2. The motor will be have a 1.2 speed increase which may give more air flow for cooling. ------ OK
3. The amps will increase due to the higher flow rate from the pump ------- will increase the motor temp, but should be OK with the added air flow due to the 1.2 speed increase.
3. The amps will increase due to the higher voltage 220 to 240V
------- could be a problem with cooling.
Conclusion: Suck it and see!!!!!!

Should be w/in tolerance, if you're in the UK Europe decreed that our current be standardised at 230 now, the cycles shouldn't matter unless it's sychronised and has to run at a certain speed, no problem for a pump.

Yes you can with Hz to spare (I tried to make a joke, didn't work...)

try it but if it doesnt work try a transformer
