What is the technical data for this ABS pumps?

[oracle_9]

I see Mike's subworks carry an ABS pump. I emailed them twice for some technical data on these things but I got no reply.

I am interested to know:

1) how heavy this thing is
2) how much liters/hour (or whatever flow rate)
3) what size tube does it require

4) are there any alternative company for this pump for subs?

Any help would be appreciated.
Thanks
