The size of your filter limits the size of the pump, a 1 hp sta rite dura glas is great pump a 1hp should do you . If you have solar 1 1/2 hp is needed to push the water up on the roof.
25 HP is 25 HP, no matter how you slice it and dice it.
1 hp = 746 watts2 hp = 1,492 watts2 hp x 1 hour = 1,492 watt-hours = 1.492 kWh(Note: The "2 hp" rating on the pump refers to the useful output, that is,the water that the pump moves. The '1.492 kWh' calculated is simply theequivalent of 2 hp-hour, expressed in a different unit. The consumptionfrom the electric utility will be more than that, because no machine is100% efficient, that is, a machine's useful output work/energy is alwaysless than the input to it.To calculate the input energy required to operate this pump at full loadfor an hour, divide 1.492 kWh by the efficiency of the pump.)
To answer this question the pump's voltage is needed.

it does not have a waterpump!
The amperage a 220 volt well pump will pull depends on the wattage of the pump. You can calculate it by dividing the wattage by the voltage (220V) to get the amperage. For example, a 1 HP well pump typically pulls around 8-10 amps at 220 volts.
