Your should be able to, but do be aware, the point above how long it take to charge with a pump from empty.
I had to go back to the pump 6 or 7 times for a full fill,
two points here 1) how knacker u are after pumping and 2) the pump will need to cool after 100 strokes ish.

DO think you will go out with a steady had after a heavey pumping session.
