12 VDC Water Pump

Koch,

In addition to 12VDC drive requirement,you must also specify the flow rate and the discharge pressure for selecting a proper TYPE of pump.

If small capacity and medium pressures are involved , you may find a local Jabsco dealer ( check yellow pages -under pumps)handy to help you.30 GPM at 30 PSI - your specs should read something like this for sending out the enquiry.If possible,also add water temperature and suction condition.

Jabsco has a flexible elastomer vane impeller as the pumping element.

If very large flow rate and low heads are involved you may find Centrifual Pumps as a better choice.All depends on these two factors.

If the water is for potablepurpose,specify Food Grade elastomer material for flexible impeller.

Trust this helps.

Thanks for your information.

Can you me the contact details of Jabsco dealers. I can't find it.

Thanks

koch.in check with a RV or trailer sales perry

Try your local recreational boating supplier. They will have 12V bilge pumps that are used for standby conditions on all sorts of small boats.

Second alternative, try your local aquarium supplier. Many will have low voltage pumps that run from step-down mains supply.

Third alternative, try to find a "hydroponic" gardening supplier. They would also often have low voltage pumps for water movement.

Also, you comment about "on and off for short intervals", is it possible to use a smaller capacity pump and so have a greater duty cycle for the "on" time in each pumping cycle? (If it is in fact on a caravan, can you fit a small pressure acumulator and then treat it like an off system household water supply.

A lot of trailers over here use this co.'s

Dear Koch

Try to investigate the sentence you mentioned " pump is put ON and OFF at SHORT intervals.Please more details about this point,because I think the problem may be at the design of the system not the pump.

Thanks

Can you not specify the requirements a bit better, Liters per minute? Pressure? Poable or not?

There is a vast range of pumps for caravans, the more you pay, the bigger (and better!) the pump.....
