The GR-4700 - Hands down the best Bilge pump brand to date.
These sluice pumps actually put out the volume they are rated and are a reliable run flat bilge pump.
That is they are made to run for years.
This pump suits any sluice range right up to the 12".
When using this pump for an 8 inch sluice you will have the added benefit of additional pressure over 3 meters of hose where a 3000 GPH bilge at 3 meters is at its limit.
Please note layflat is not suited to bilge pumps they restrict flow too much.
