Electric Water pumps
hi all
Im running a Davies Craig electric pump on my twincam but noticed that in high ambient temps the engine is running warmer than it likes. I suspect
that it is too powerful and is cavitating.
I retained the original water pump (it's hard to lose) and now want to try a test using it.
My question is, can I get away with leaving the electric pump in the circuit and merely remove the power supply or should I remove and re plumb.
Thoughts gratefully received
Many thanks
Gavin

I have one in the garage, when its plumbed into the circuit with the original pump, doesnt it need the impeller removed. Recall the destructions
suggested that.
Two pumps with different flow rates in the same circuit ? cavitation maybe ?

suspect the original pump (or rather the impeller) is causing a blockage, stopping the electric pump doing its work. think you normally remove the
orginal impeller, or the whole pump and plate ver the hole. the craig david (as i call them) pumps do have an optional speed controller, that can
adjust the speed with the temperature.
so, i reckon you need to remove one of the pumps, make sure a thermostat is fitted, and if you keep the electric pump, might be worth getting the
speed controller to go with it.

Would think you'll need to divert around it, as in order for it to pump water it needs to be "sealed" against water just slipping
past. Might be worth a test leaving it in place, but keep a very close eye on temps.

I have the very same pump on my engine too. Give me a rewind 
Thank's, Joe
