To calculate the required current for your pump in amps you need to know both the power in Watts and the Voltage of the pump, you would then take the power and divide it by the voltage. This is represented by the following formula:

Power / Voltage = Current

An example of this is if you had a 5.5kW (5500W) with a voltage of 12V to find the current you would divide 5500W by 12V to give a current of 458 amps.
