Freshwater pump

Nick Newington

I have not had any luck sourcing the spares kit for the original AMFA freshwater pressure pump. IMNASA have no stock.

So much for my faith that the impeller would last forever with only freshwater use, it seams that the bronze impeller is worn slightly and now the pump does not like to prime as well as it used to when the tank is nearly empty. Tell tale sign is that it is beginning to fail.

So I am thinking of going for one of Marco’s pumps. The one I like is the UP 12/A 24v. It pumps 36 litres per minute. Could just fit on top of the existing pressure vessel. Retail price 571 euros, but there is a discount available…

I have considered the electronic controlled ones but think that it is likely to be less reliable, and more costly. It may be more efficient and can, according to Marco be installed without a pressure vessel. So I see that advantage, but then I read that it is better to use a pressure vessel. So what is the advantage?

In my book the less electronic controls the better, especially considering the basic set up, with the current pump which worked flawlessly for 16 years; simple mechanical pressure switch, the same as on the Marco, a pressure vessel to damp cycling and cushion the loads that I will continue to use.

Before I make the order I am open to persuasion as to a better option. Any opinions out there?

Kind regards

Nick,

The A.F.M.A., Reya, and other manufacturers of the 66B and 88b Freshwater pumps use the same kit for the 66 and 88. I know that there are at least 50 of these kits aboard boats that purchased newer pumps. Hopefully one of them will have a kit for you.

My favorite replacement is the Gianneschi Pump. It is high quality and has a simple design. Amel used them in the A55, A50, and possibly the A60.

These are available for a discount if you mention Amel School or me from two Ginneschi distributors. They are also available in better marine shops throughout Europe and the US.

Nick,

I installed the Marco UP/6E without a pressure vessel at first. I would not recommend that.

Because of our freshwater heads, there's an issue called the "hammer effect" when the toilet water solenoids close, sending a shockwave back through the freshwater system.

Because our freshwater piping is rigid, the shockwave energy finds the weakest point, which happens to be the seal between the motor and pump head on the Marco pump. That results in a flooded pump motor.

After figuring this out (mid ocean), I ordered the stainless pressure tank. Has worked like a charm for 3+ years since.

Conclusion: buy the UP-6/E and the pressure vessel.

Re: sizing - I opted for the UP-6/E in case there was a massive leak somewhere while I was away from the boat. The flow rate was close to or slightly below my bilge pump rating.

Hi Nick,

We changed our original FW pump out for a Marco UP14/E about 6 years ago and it is the best FW pump I've ever had.The flow is variable according to demand and it keeps up with multiple outlets open at the same time, unlike the mechanically pressure switched pumos that are either on or off.
We have a snall 1 litre accumulator tank in the circuit as the boat piping is rigid and the Marco pump does need some elastic absorbing facility - if all the plumbing was rubber hoses, you could probably get away without a tank.
The electronic control has been 100% reliable unlike the agricultural Square D type switch on the old pump....no maintenance, none.
We always turn off the FW pump when leaving the boat.

Good luck
Cheers

Marco recommends an accumulator tank if the vessel's plumbing is rigid like the PEX in Amel 54s and later.

For a SM with hoses the accumulator tank is not needed.

Hello Nick,

I installed a 12A on my SM007 (Eleuthera) when the previous pump went AWOL. I also removed the pressure vessel and added about 1.5 meter hose as per Marco’s instructions and this was sufficient.

There is a very short delay for the pump to start but not enough to make a big difference in total delivery.

Kind regards,

re the pressure vessel....
When I orginally installed the Marco pump I didn't include a pressure vessel.
The pump cycled off and on, I asked Marco and they suggested adding a small pressure vessel. That cured it.
JP on Eleuthra added an additional length of flexible hose after the pump, that seemed to work OK too.

Hi all,

Faced with limited availability (and time) at the moment we needed to replace the already non-OEM freshwater pump, I elected to go for a generic electronically-controlled variable-speed constant-pressure pump, the JABSCO model 42755-0394 (so-called VFlo5), providing 19 LPM (5.0 GPM).

I was advised by Frank in Martinique that the electronic controller of the VFlo series pumps does not take kindly to being hooked up to a run-indicator lamp, such as we have on our 24v DC panel - apparently, doing so destroys the electronic controller.  Rather than test this advice, we have done without the indicator lamp since moving aboard.  We are as a consequence well attuned to the sound of the pump when operating.

The original VFlo5 I installed failed after 12 months, but the replacement has been running satisfactorily now for almost 5 years (touch wood).  I believe that the JABSCO 42755-series pumps are now obsolete, replaced by the functionally identical R4426 & R4320 series pumps by JABSCO's parent company XYLEM.  I understand the parts are interchangeable.

Hi David,

About 10 years ago we switched to an ordinary Jabsco model. Slightly noisier, more powerful ( we don't have showering teenagers on board ! ) . Cheaper than the original Amel pump. We carry a spare.

It did not occur to me not to hook it up to the indicator light.

Both pump and light are still working.

Please get in touch with Dott.ssa Chiara Fruzza from Gianneschi. She is very helpful (and a Doctor btw); - I explained what kind of pumps (Climma and Fresh Water pump) I have on Board and she directed me to the right dealer (See e-mail below). The two Pumps are Autoclave systems CB 20 ME and the ACB 61 G.

Both Climma and Fresh Water are Italian brand and I got the complete set including Seals, O-rings, capacitors, etc. I was very happy and I rebuild the Climma Pump who was leaking. The Freshwater is still working well but the 8lt. accumulator tank bladder was defect, so I changed it completely was only 77€.

Happy sailig

I didn't notice much of a difference but I have to admit I don't blast the water at full volume very often.

With the UP6/E, even our cockpit sprayer provides plenty of volume. When leaving all taps open to, say, empty out all 900 liters after a bleach cleaning, the bilge pump barely keeps up. I wouldn't want more flow, personally.

Hi David,

I also changed out the Amel pump to a Jabsco pump.

My only worry that it is a continuous flow pump at 50 PSI.

The Amel pump was about 25-30 PSI.

I plumbed in a temporary pressure gauge and lowered the pressure to 30 PSI.

I was concerned about the plumbing and the higher pressure.

I also carry a spare pump and a complete replacement pump rebuild parts.

To wire the pump indicator light on the DC panel it is quite simple. Just splice the wire from the old pump into the wire that goes to the motor on the new Jabsco pump. The wire on my pump is red.

Hi Eric, et al,

Thanks for your various guidance on splicing-in the reporting wire.

Yes, it is easily possible to install a pump with a higher-than-desirable operating pressure.  As it happened, such a unit (a 60psi high-volume deck-wash pump) was installed on SM#396 as the freshwater pump when I took possession - this was the first thing I changed.

In relation to the Jabsco VFLO and, newly, the XYLEM R4 model range, this is my personal decode of the model numbering schema:

Jabsco VFLO 5.0 series: constant-pressure variable-speed 5.0gpm/19lpm pumps, 
  Series ID: 42755-0x9y;
    "x" denotes the operating pressure ('0' = 40psi; '3' = 25psi)
    "y" denotes the operating voltage ('2' = 12v; '4' = 24v)

    Hence:
      42755-0094; 24v; operating 40psi; Shut Off @ 60psi
      42755-0394; 24v; operating 25psi; Shut Off @ 35psi

Relating this to the new XYLEM-branded VFLO model numbers R4xxxy43A, where (it seems that):
  Variable "xxx": value '426' denotes 40psi; '320' denotes 25psi
  Variable "y": value '1' denotes 12v; '3' denotes 24v
    Hence:
      R4320343A is the 24v model with 25psi (1.7Bar) operating pressure with shut-off @35psi (2.4Bar)

If anyone has further info on this pump model decode, please share.  In the interim, I hope this info may be of assistance.

Hi David,
I also changed out the Amel pump to a Jabsco pump.
My only worry that it is a continuous flow pump at 50 PSI.
The Amel pump was about 25-30 PSI.
I plumbed in a temporary pressure gauge and lowered the pressure to 30 PSI.
I was concerned about the plumbing and the higher pressure.
I also carry a spare pump and a complete replacement pump rebuild parts.

To wire the pump indicator light on the DC panel it is quite simple. Just splice the wire from the old pump into the wire that goes to the motor on the new Jabsco pump. The wire on my pump is red.

Hi David,

About 10 years ago we switched to an ordinary Jabsco model. Slightly noisier, more powerful ( we don't have showering teenagers on board ! ) . Cheaper than the original Amel pump. We carry a spare.

It did not occur to me not to hook it up to the indicator light. 

Both pump and light are still working.

Hi all,

Faced with limited availability (and time) at the moment we needed to replace the already non-OEM freshwater pump, I elected to go for a generic electronically-controlled variable-speed constant-pressure pump, the JABSCO model 42755-0394 (so-called VFlo5), providing 19 LPM (5.0 GPM).

I was advised by Frank in Martinique that the electronic controller of the VFlo series pumps does not take kindly to being hooked up to a run-indicator lamp, such as we have on our 24v DC panel - apparently, doing so destroys the electronic controller. Rather than test this advice, we have done without the indicator lamp since moving aboard. We are as a consequence well attuned to the sound of the pump when operating.

The original VFlo5 I installed failed after 12 months, but the replacement has been running satisfactorily now for almost 5 years (touch wood). I believe that the JABSCO 42755-series pumps are now obsolete, replaced by the functionally identical R4426 & R4320 series pumps by JABSCO's parent company XYLEM. I understand the parts are interchangeable.

Subject: [AmelYachtOwners] Freshwater pump

I have not had any luck sourcing the spares kit for the original AMFA freshwater pressure pump. IMNASA have no stock.

So much for my faith that the impeller would last forever with only freshwater use, it seams that the bronze impeller is worn slightly and now the pump does not like to prime as well as it used to when the tank is nearly empty. Tell tale sign is that it is beginning to fail.

So I am thinking of going for one of Marco’s pumps. The one I like is the UP 12/A 24v. It pumps 36 litres per minute. Could just fit on top of the existing pressure vessel. Retail price 571 euros, but there is a discount available…

I have considered the electronic controlled ones but think that it is likely to be less reliable, and more costly. It may be more efficient and can, according to Marco be installed without a pressure vessel. So I see that advantage, but then I read that it is better to use a pressure vessel. So what is the advantage?

In my book the less electronic controls the better, especially considering the basic set up, with the current pump which worked flawlessly for 16 years; simple mechanical pressure switch, the same as on the Marco, a pressure vessel to damp cycling and cushion the loads that I will continue to use.

Before I make the order I am open to persuasion as to a better option. Any opinions out there?

Kind regards

Nick Newington
