I've been using a car windscreen washer pump for about a year (intermittent use) with no problems. There are two types readily available. One is a diaphragm pump the other a small gear pump with plastic gears. I'm using the gear type as the gears could easily be replaced with metal ones later if necessary.
Plastic food container makes a suitable tank.

Anyone know of a source for a cheap and cheerful Suds Pump?

I'm using a bilge-pump. Quite cheap (in the 15 BPL range), but they need
12V.Nick
I'm using several Little Giant submersible pumps as suds pumps on various drills and saws. US brand that seems available worldwide and well priced. Work well, just need to check specs for head rating.

What I've got on my lathe is a 12V electric fuel pump which wasn't needed on a previous vehicle, powered by a cheap 4A battery charger with a largish capacitor blagged from some dud bit of apparatus in parallel - it needs the cap. otherwise it doesn't drive the pump properly.
It's an "SU" type pump, the kind that stops pumping when it's up to pressure. The charger sits in the motor housing bit and is wired in parallel with the motor so that it starts when you start the machine.
the only other thing it's got is a normal in-line petrol filter on the pickup in the tank, so that it filters the suds and doesn't suck up minor crud into the pump.
Thanks to all who responded - I got a BMW windscreen washer pump ( slightly newer than my geriatric ML7) for 99p on ebay and it works a treat
These motors are not designed for continuous running. So if ,as I suspect, the flow rate is more than adequate for your needs, motor life will be much prolonged by running from a lower voltage. It might be worth looking out for a similar model to keep on the shelf as a spare.

My system uses a fuel pump instead.
Maybe £12 for a motor car screen washer pump,
Many thanks for all the replies - I settled on a Merc. Windscreen washer pump and bottle from Mondial Enterprises Ltd. £5-74 including post.
Tried it today and it seems to work just fine - I already had a number of
12v psu's.On "A better drill pump" I posted
"Have you ever thought about using a "bubble lifter" like those used to lift water to tropical fish aquaria filters?"
