If you are afraid of bending the tyre tube then buy this flexible hose pipe. It will help you a lot..
After damaging/bending a valve with a small handheld pump I was sold this which adds some flex while pumping. It does the trick :-)
Easy to fit
is there any video for connecting this hose with Btwin FLP-5000 Floor Pump
You should be able to attatch the threaded (male) end of the hose to the valve on the floor pump if you put it in "presta" mode.

Got it for the Presta adaptor as I use a car pump with a pressure gauge. It works well no problems.
