Swap Drinksafe waterbag for hand pump filter.

[RE8ELD0G]

I am looking to swap my Drinksafe-systems 8L waterbag and filter system with Olive green bag.
http://www.drinksafe-systems.co.uk/products.php (its at the very bottom of this page link)
It is a great gravity feed camp system and has worked well for me, but i need something that i can pump the water.
I think i have a spare filter cartridge and the one in it has only had appx 50L through it of a possible 1600..!!!
Its in perfect condition.

Im looking for a Katadyn or MSR pump type filter.

Thanks

Would also swap for a msr or primus multifuel stove.
