Question Jabsco PAR-Max for Salt Water ?

Hi Folks.

Can I use a Jabsco Par Max 1.9 or 2.9 31395 for salt water?


If not, WHY not?

Exactly why not. i.e don't tell me they are only fresh water pumps because there's nothing in all their literature that says they are only fresh water pumps.

I want it for a galley sink pump for salt water. I do not want to use a deck wash pump for it. The decision is between a 31395 Par Max or another manual foot pump.

31395 Series PAR-Max 2.9 > ITT Flow Control - Engineered for life.


Thanky brainy types.



Mark

Yes, thanks for that, but its a wash down pump, double the price, high amps, and 3/4 inch inlet/outlet where I want 1/2.

The one I mention is what I want, or not at all

But thanks for looking

Re: Jabsco Par Max for Salt Water?

I think the big difference between the pump you are looking at and the washdown pumps is that the motor has some sort of clear water resistant coating (epoxy?). The motor on the pump you are looking at is just painted black and will rust quickly if it gets wet. The pressure switch on the wash down pump may be better protected as well. If you mount it in a nice dry location, and no saltwater leaks on it, I don't think you'll have a problem. Spray it with Boeshield, Corrosion Block or something similar before you install it. I think everything inside the pump is stainless steel, rubber or plastic. Why don't you just email Jabsco and ask them to make sure I'm correct about the internal parts being salt water resistant? Their customer service is usually very good. Almost as good as Hopkins-Carter!

Re: Jabsco Par Max for Salt Water?

Go to a boat parts store and look at the rebuild kits for the different pumps. If the parts are the same, then using it for salt water or fresh water should make no difference.
- - However a very good strainer before the pump would be a good idea to keep sea life and other debris from passing through the pump.
- - If the pump is not used very often I suspect you will need to take it apart and remove crystallized salt from the insides of the pumping mechanisms and pressure switch every so often.

Re: Jabsco PAR-Max for Salt Water ?

Salt water pumps are more corrosion resistant...bottom line. For a pump like this that draws salt water you absolutely need an inline strainer to keep critters or plant life from clogging it.

You can run the fresh water pump for some time before it corrodes out. Corrosion resistant coatings will probably last for about three minutes inside an impeller housing.

Re: Jabsco PAR-Max for Salt Water ?

David and Orsirissail are right about this needing a strainer. I don't think you will have an internal corrosion problem for a long time. The pump is mostly plastic and rubber. The fasteners appear to be stainless steel. The only thing that could benefit from a corrosion resistant coating is the outside of the motor. There is no impeller, this is a diaphram pump. It has a three year warranty and Jabsco says it's "Corrosion Resistant".

Re: Jabsco PAR-Max for Salt Water ?

Thanks guys for the advice

I bought it and am half way through installing it.

It only cost double the cheapest internet price I could find. Yippee

I had a spare strainer so I'm putting that in.

Then the "10 Minute Job Turns into 2 day Job Fiascos":
Changing some pipe sizes and had to buy some weird plastic connectors (etc)
Had to change over some metal fittings that I bought in Malaysia non-ss to plastic.
Rocker switch to run pump only while my toe is on it. (Safety thing about pumping sea water inside the boat if a normal switch/tap is forgotten to be turned off)


I should be able to do the dishes in about a months time.

I LOVE Boats!


Great Win of the Day:
The rocker switch fits exactly in the hole where the old foot pump peddle comes out through the cabinet work It looks great! Can't see the original hole at all

Things must have changed down there, last time I was there the prices were triple or quadruple. So much so it became cost effective to have the stuff shipped in from Florida.

For non time sensitive stuff I agree totally.

Re: Jabsco PAR-Max for Salt Water ?

MarkJ,

What happen to looking for galley wenches for dish washing. Do you NOT have the plastic bucket that a cruisers should have for hoisting aboard salt water for doing dishes. It would not have taken much instruction to have shown the new galley wench the process of dipping bucket attached to rope in to the warm water and returning said bucket almost full of seawater to galley area. Then informing her the proper techinque of washing the dishes, rinsing with fresh water and stowing away... OH, you have crushed my ideas of a swash buckling man of the sea without his trusted wench to assist him in the never ending chores of maintaining a proper sailing vessel.
Oh, cursed be you our man of the Grenadian Isles.......

I had one wench a few days ago and told her not to touch my pride and joy bucket. I told her to grab the plates and go for a swim.

But the tide was going out and I haven't seen her since.




Hence the 'leccy pump

Re: Jabsco PAR-Max for Salt Water ?

Ahoy Mark, I had one on the new yacht that I bought , for salt water in the galley, so useful, but it corroded outand started leaking into the bilge after 2 months. So now have the foot operated diaphram whale pump in the galley. Also, no leaking , stray currents onto the hull or fixtures unless you wire in a double pole switch for both the positive and negative feeds to the pump.
Maybe try the 18 yo lassy out of Cape town? A capable dish washer????

All the best from Keith, back in Sibolga and the Banyak Islands.

Re: Jabsco PAR-Max for Salt Water ?

Good point, surfmachine. I also use a foot pump, (show below) for the sea water spigot in the galley sink. The thought being if the electrics or electric systems fail then I can still pump water into the galley sink. Also it is a diaphragm pump so it less affected by stray critters working their way through the system.
- - Additionally, sea water sitting in pipes/hoses tends to develop a rotten egg odor after awhile. I use the foot pump to purge the old sea water out of the system.
