some questions

[bam~bam]

Hi, today I went to a friend
his father is a cooling guy
I've recieved some insulation and a pump that I can try

the pump is a KNF 79
http://www.google.be/search?q=cache:N7x7se0AzJkJ:www.knf.com/pdfs/n72_79.pdf+KNF+N79&hl=nl&client=firefox-a
the max flow is 552l / houre or 9.2l / minute or 164 gallons
the max vaccuum is 160 mbar abs. (25.2 in. Hg)
the Max. Continuous Pressure is 0.5 bar (7 psig)

is this a good pump for waterchilling and a swiftech and frigus ( frigus.nl ) block?

5 questions

1 / This is a litle preview what my insulating of my tubing would like, is it good?
2 / That big mouse think is the only insulating thing i would use for my tubing, is that ok or do I need more?
3 / Is it alloud to use black tape everywhere on the insulating?
4 / this tubing i'm using is no tygon or normal tubing but "garden-long"* is that ok? there is rubben in the inside and some painted rubber or plastic on the outside
5 / inside that tubing, in the rubber there is some cotton, is that bad?

thanks
