Basically they are motor loads, for 3 phase induction motors voltage variation at motor nameplate frequency must be within plus or minus 10% and frequency variations at motor nameplate voltage must be within plus or minus 5%. The combined variation of voltage and frequency must be limited to the arithmetic sum of 10%. What is important is the flux density ratio, which is the ratio of line voltage over line frequency. If a 415V 50Hz motor with an FDR of 8.3vhz was to operate on 460V 60Hz with a FDR of 7.66vhz this would be okay as the percent variation is 8.35& which is below the 10% allowable arithmetic variation.
However single phase motors usually in case of fans should be analyzed properly as single phase motor does not have an inherent rotational aspect to it. It has an additional start winding is required to provide rotational starting torque. 50Hz motor placed into 60Hz service may switch off the start winding at too low a speed for the motor to make the transition to running.
With fans, look at the fan curve. Changing from 50Hz to 60Hz increases the rotation speed of the fan to require more power than the motor is capable of. This may well push the fan to overload. Fans are usually sized very close to the available power of the motor and have little margin. Many have to change to a fan with less pitch to operate at the higher speed. Simple enough to do ahead of time but not so if you learn about after burning out the motor.
The lower the frequency, the more iron needed in an induction motor, that is why you can go higher in frequency, not lower. Lots of stuff is rated "50/60 Hz" look at the nameplate. A 50Hz AC induction motor will try to run 20% faster with about a 20% reduction in torque, because the current will be lower due to the higher impedance at the higher frequency. Nominally the frequency should be proportional to the voltage; modern variable speed AC motor drive electronics does that automatically.
Otherwise, you can simply buy a static frequency converter from GoHz to convert 50 Hz to 60 Hz, or vice, for different appliances compatibility.

From 50Hz to 60Hz represents 20% more energy per second than the engine needs to transform and dissipate. It has an effect on the speed of rotation (more rapid) the thermomagnetic losses and the vibrations of the engine. Its reliability depends on the type of asynchronous or synchronous motor, application and ambient temperature. For the asynchronous type with use at 100% of its nominal power, it is more prudent to provide a GoHz frequency converter to adjust the correct operating frequency, for use less than 80% of its rated power should have no problems. For a synchronous motor type, in all cases, provide a frequency converter to adjust the correct operating frequency.

Can any ABS pump rated to 415 Volts and 60 Hz be used in a source supply of 415V and 50 Hz
Depends on the actual load (brake horsepower) required by the pumping process.
Operating at 50 Hz (instead of the "design point" of 60 Hz means the machine is only turning at 5/6 or rated speed - e.g. roughly 83 percent. It also means the motor is further along the magnetic saturation curve by the reverse proportion (6/5 = 120%). Together, these indicate that the machine will exhibit much higher than the original design thermal stress (temperature rise).
The best thing to do, in terms of obtaining system longevity and reliability, is to get a machine designed for the appropriate power, speed, voltage and frequency. Failing that, find a way to keep the volt-per-hertz ratio the same (e.g. use a transformer or other means to drop the line voltage seen by the motor to 5/6 of 415 nominal, when operating on 50 Hz).

If you want to supply your ABS pump by using power source which has different frequency than it is written at the nameplate of your ABS pump, you need to take care about value of magnetic induction in ferromagnetic core of your ABS pump, because of possibility of appearing of unallowed warming of ferromagnetic core which can contribute to damaging of ferromagnetic core of your ABS pump. This fact is a consequence of entering magnetizing curve into area of saturation in H-B characteristic which describes behavior of magnetic induction in depends of intensity of magnetic field. In the area of saturation, as long as you would like to increase voltage, magnetic induction will stay at the same value which is the equal with value of magnetic induction under nominal voltage. So, by increasing voltage you will have only unallowed warming of ferromagnetic core, so you need to take care about ratio of voltage and frequency:
U1/f1=U2/f2=const. => 415/60=U2/50 => U2=345,83V=Umax allowed
U1/f1=U2/f2=const. => 415/60=U2/50 => U2=345,83V=Umax allowed
