advice needed on pump issue

pump

what about a peristaltic pump, the type used in norbert bruggens sub kits, i use these in my model subs, they will pump in both directions, there is a silicon tube which is squeezed by rollers driven by the motor.....

12 volts is no problem.... and they too self prime, plus once the motor is switched off there is 'no leakage' in either direction as the silicon tube remains crimped....

they are available via norbert but you can get them direct from gardner denver

I am into big boats (not models!) too and wonder if you could use bilge pumps. The small ones are about 500 gallons per hour (that should do the trick!!) but importantly some are submersible and nearly all 12V. Get one without a built in float switch so you can switch it on and off.

I have never tried to see if it pumps in reverse, probably not because the impellor would be wrong.

The small ones are about the size of a 100mm tin of paint so may be too big?
