I have a number of Silca frame pumps and I NEVER wrestle the head off the valve stem. When I'm finished pumping I give the pump head a sharp rap with my hand to disengage the pump from the valve. Any twisting motion whilst removing the pump from the valve can cause the valve itself to twist and loosen from the tube or come off entirely.
Cheers
