Which cars have electric water pumps. I read somewhere an Omega may have two pumps....why? Does anyone know the capacity of a pump?
I am considering fitting one to a Lotus Elan.

Hello and welcome :y :y
Can't answer the capacity question but the electric pump is a secondary pump as part of the Winter Pack, to enable the heater to be used with the engine off... I wouldn't have thought it would have a good enough flow rate for general cooling though :-/ :-/
-
I think all the Omegas (or maybe just all the V6's) have an auxiliary pump on the side of the radiator.
Some cars (probably those with a winter pack and Elites) have another pump to pump water round the heater matrix when the engine is off.
The pump isn't big enough for the full cooling duty but if you have marginal cooling when stuck in traffic it might be just what you are looking for.
I think the pump connections are about 3/4" diameter.

Our 2.5 has the pump and it helps keep inside warm with the engine off. ign on. wouldn't a cooling fan or larger rad be better?

Neither of the electric pumps would flow enough coolant to be the primary coolant pump on an engine.
You'd need something like a Davies Craig pump for that, at a price. :(
