H2O pump

[Tim Powell]

I have a grate AC fresh water pump its a stainless well pump. Grate pressure and always workes .I have a galey maid DC back up its a POS. (cooked) Looking to replace it what about some ideas. No west marine one time wonders. Pacific model and brand would be appreciated. Gotta be 24 volt.

We have the Headhunter Caliber, which provides plenty of pressure.

It s hard to go wrong with a headhunter whether AC or DC mode. They re a bit pricey so as a back up it maybe overkill unless you depend a lot of time on the hook without running the genset

If you re always on genset then a basic DC marine diaphragm pump is all you need

I am looking to do the same thing. I have a craftsman shallow well jet pump for the main pump. Works well and has lasted a long time. My spare AC pump went out and I want to replace. I am also thinking of putting in a D.C. Pump. All the diaphragm pumps seem to only put out 5 gpm. I think you need to be around 10gpm for showers? The Headhunter pumps are $$$. Tried going the China route as a spare AC pump, but that died within months.

I would get a Groco- call them, they are in MD, and see if they make 24 volt. Every part of a Groco system is rebuildable and they are very well made. Ask for John Cly, I think it is, when you call them. All their stuff is made in USA< btw.

We have a small back up shurflo diaphragm pump, 7GPM I think. I test it once in a while by turning off the 240v headhunter. It s fine. Enough for a couple of showers running at the same time

With flow restrictor shower heads, you can get a nice shower using 2 gpm.

Not sure if you want to get another one but you could always call Raz Marine and see about getting a pump from them. They might take the one you have as a core. Or they will pay you for it if you dont want to get another.

I ended up buying a headhunter for my primary AC pump. It is whisper quiet. I will use the craftsman well pump for the secondary AC pump, and installed a diaphragm D.C. pump as a back up if I loose AC power.

One issue with the Mach 5 is that it is pretty sensitive to intake air leaks as well as heat in the ER. There is a water temp sensor in the pump which will shut it down. I ve had issues with this on two different boats, even with new pumps after a run.

The pump is so quiet it can easily be mounted outside the ER

This is one of the reasons I included a pump room in the new layout of my 53, port side, behind the ER where the midship head wished to be. I have the fresh water pump, vacuflush, water filters, jacuzzi pump, etc and eventually will install the water maker controls there although the noisy high press pump will go in the ER

Tim - we have the 24V Shurflo Aqua King II 55 psi, 5.0 GPM. It moves some serious water, multiple showers simultaneously, washer, dishwasher, etc. We decided to keep the GM 32V as a back up (I fabricated a simple manifold and added switches in the port ER). Shurflo is a little quieter than the GM but not much. Good luck...

If you haven't already decided from the several great suggestions......call Depco pump and ask what options they have to recommend. Always wonderful service and pricing for us.

 

[tonytrakovich]

Thanks for the info Pascal. If the pump quits working on the next trip, I won't have to do much troubleshooting.

So my GM water pump after rebuilding the impeller assembly just bogs dowrn and trips the breaker. Thinking about yanking it and replacing.Reading the prior threads, it seems there are two camps: DC diaphragm advocates and shallow well proponents. I would think a DC pump would be easier as the 32v lines are already there. The shallow well or jet pump option would require a 120v extension from the inverter.Seeking insight from the group

If you leave the dock for more than a few hours you need both AC and DC pumps.

A diaphragm pump is fine as a back up,although they re getting harder to find in32v But as a primary either a shallow well or a Headhunter Mach 5 is beast as a primary. The head hunter is about $1000 but very quiet. A goo dshallow well is $200/300 but a bit louder.

That's our set up on the 84 lazzara i run. Whenever the ER is hot and we don't use a lot of water the mach5 trips and the shurflo kicks in although with reduced pressure.

Talk with the folks at Razz Marine. You could need a motor rebuild or have a wiring issue. At what pressure does it die?

 

[carolinacoast]

we have 1 of each. the redundancy of different power sources and pumps has helped a couple of times.

Met a couple with a 53 in the bahamas that lived aboard a few months a year, and organized fishing tournaments. He had 2 shallow well pumps, and a third in the box. important to have low pressure cutoff switches so you dont burn impellers in either.

Any decent auto electric shop can rebuild the GM 32V motor for considerably less than RAZ. Nothing against RAZ, just shipping that thing back and forth adds up. Barring any other complaints about the system, this seems like it might be the easiest all around fix.

Flowjet still makes 32 volt diaphram pumps. Should be readily available. Got mine from Fisheries Supply, they have free shipping. John

I understand that but they are excellent at helping diagnosing these issues.
