Water Pump - Talbot Sunbeam 930
Water Pump - Talbot Sunbeam 930
Does anyone have any info about fitting the B1 engine water pump to the standard Imp engine. Is it a better pump ? It seems to be more easily available and cheaper but I'm a bit confused as to whether the same pump was fitted to the 1.3 and 1.6 models. It also seems the pumps are different for fixed fans and electric fans. Has anyone done a conversion ?

Hi Beebee
Use these on all my Imps and Davrian. Very neat when running a fromt rad, and yes I am sure they are better than an Imp one.
The front part of the pump is the same for the 1.3, 1.6 Talbot / Avenger. It is just that the 930 Sumbeam has a remote housing rear section.
You're right regarding different types depending on fan type, but that just refers to the flange on the shaft where the pulley bolts on. So this can be rectified whilst choosing a pulley configuration.
The 930 housing has a flange on the base, that has an elbow bolted on, which also houses the thermostat. If you disregard the elbow/thermostat and blank that off with some bracketry, you can then hang the alternator off it which also tidies up the engine bay.
Hope the pictures explain all....

Hi Graham
Thanks for all the advice and the excellent photos. I can now understand the appearance of pumps for sale which seem to show only the front part of the pump. I suppose the remote housing rear section would be a separate item. I have a 930 pump on a B1 engine, but I'm reluctant to transfer it to my Imp engine as I don't know it's condition. I would prefer a complete new pump but new items for sale are confusing.
I like the arrangement for mounting the alternator - as you say - very neat. The brackets are no problem but the pulley wheel looks like a custom job.
Recently I noticed that some performance Imp/Davrian cars have electric water pumps fitted to replace the belt-driven pumps (but costing up to £180 !!) My car is road-going but I wondered if there were any advantages apart from a few more bhp. Have you heard anything about electric pumps ?
Regards
Bob

Re: Water Pump - Talbot Sunbeam 930
I decided it would be a good idea to use the 930 pump. I now find that the 'pumps' advertised do not include the impeller housing. These 'pumps' are only worth buying if you already have a housing. I have not managed to find anyone selling complete pumps or impeller housings.
This is typical of what is widely on sale
So where do we go from here ?

Hi Bob, I have fitted an electric pump on my davrian, very worth while
the engine runs at 90 degrees despite all the right foot can give!
If you look at the pic in car logger you will see i have modified the
imp casting to take the pump. If this is not to clear i will try and find
some more pic of it.

Hi Dave
Thanks for your advice. You've got so many photos of your Mk6 I couldn't find the one you describe. In any case I've seen how it's done.
My main concern is reliability. Overheating is the kiss of death for an Imp engine. Fan belt failure is a rare event in a road car and I'm not sure about the life of an electric motor which runs continuously in a quite hostile environment.
Let me know what you think. I'm grateful for your help.

Hi Bob, As far as I'm aware they are reliable ,I have a control box and you can
set it to any temp you want. Also use K seal in the water, I use it in all
engines I rebuild not just imp but Astons, bentley, It wont block the rad
but it will stop the odd leak in the system. I personally I like them.
All the Best.
