How many pumps does the iK sprayer take?

You pump the sprayer to pressurize the air inside the compartment, meaning if there is more air (low water/soap level), it will require more pumps to fully pressurize it, and vice versa.

The release valve on the top of the sprayer will make a noise to let you know when you have reached maximum pressure, and will ensure you do not over pressurize the compartment.
