Sean 8 metres or 26' 4" is past the limit of the majority of pumps.
With this small Jabsco pump, you could always lower it half way down the
bore if the
bore casing is large enough. I should imagine it would fit down a 152mm/6"
bore casing. You get a flow out of the Jabsco like a good 12mm/½" garden hose. It is a normal type Jabsco rubber impellor pump.
Just looking at the available 12v pumps. The specs on boat bilge pumps generally cut out at 5 metres head (height above pump) as they would have been ideal and would fit down a 152mm
bore casing. Looking at the submersible pumps, they have a maximum head of 9.7metres and at 8 metres would not give you sufficient useful flow.
Interesting, in the Jabsco Puppy range specifications, they don't give you any graphs unfortunatly, but they class thei hig pressure pump at 900 litres per hour at 3 metre head. I think that may be a misprint, because of what they are claiming the pump is suitable to be used for eg: high pressure deck washing. The Jabsco part number is 22010-2653. This pump by the looks of things would fit down a 152mm
bore casing. I would go to www.biasboating.com.au and ask them to send you a performance graph for that pump. It is also self priming up to 1.5metre.
