   Thanks for the confirmation on the duckbills being nitrile in the Sealand pump.  I suspect that this pump would be great for pumping the sump.   What is you opinion about the capacity of this pump in regards to being the sole electric bilge pump aboard?   I am used to installing centrifugal pumps in boats this size with ratings 10X higher.  I think something as small as a 1/2” hole 4’ below the WL would flow almost 8 GPM….

The only rubber in the T-series pumps in contact with pumped water are the joker valves.  

The sealand joker valves (they call them "duckbill valves") are made of nitrile rubber, which is good for oil contact.
