Why no accumulator?

[markdoane]

I put an accumulator and a VSD pump in my Tradewind. I even mounted the pump on special vibration isolation bushings.

The results were interesting. The accumulator will store 1/2 gal of water under pressure. When you open a tap, the water comes out very nicely, then you start to hear a gentle moan in the background as the pump spools up to speed.

It sounds like this:
. . . . bl . . . blip . . . . blip blip. . . . .blipitty blipitty blipitty blipitty blipittyblipittyblipittyblipittyblipittyblipittybl ip . . . blip blip . . .blip. . . . bl . . . .

It's very soothing.

I was gonna post some pictures, but I am evidently WAY OVER my picture limit.

Maybe you should just post an MP-3

As an alternative, check out the new generation of quiet, variable speed water pumps from ShurFlo. They give you residential-like pressure and no buzzing or hammering. I've been putting a lot of these in the MoHo's I service, and have one waiting for me to install in my CCD.

Hey Lew, What do you suggest for the ShurFlo pump size and model for a 2007 Safari 27?

Thanks for all the excellent advice.

wj,

IIRC, they have a 4.2 gpm and a 5.7 gpm in their quiet series. I'll get the #'s, specifications and MSRP for you tomorrow.

i purchased yesterday a new:

ShurFlo Extreme Series Smart Sensor 4.0 to replace my prefectly good, loud, hammering water pump from the factory.

• Flow of 4.0 GPM [15.14 Lpm]
• Variable Speed Pump Controlled by Smart Sensor (trade mark sensor)
• High Pressure @ 50 PSI No Pressure Switch Needed
• Silent operation at any Flow/Pressure Condition
• No Rapid Cycling
• Seamless Heat Electro-Coated Motor Shell
• 4 Chamber Design
• Large Inlet and outlet Valve Passages
• Automatic Voltage Protection
• Current Limiting at 10 Amps Max.

purchased at RV Toy Outlet: price $160.99 tax $11.67 shipping $8.96 your price may vary as i'm lazy and didn't shop the part for price...

so i got that workin for me and you don't need a seperate accumulator tank.

Thanks Kev,

That's the pump that I was going to get the specs on for the thread. Mine is sitting in my fresh water bay, but is not connected yet. I've been replacing a lot of water pumps lately on big MoHos and these seem to be the favorite.

BTW, I could-a saved you some $$$$$ on that pump.

mr lew,

i am ill.

RT (Retail Therapy) requires that i act implusively and like right away. as i said, i replaced a perfectly good water pump for another... could be plant fumes, but then again i can't remember...

PRT or Performance Retail Therapy is even more dramatic. i torch the 'dream stream and just start over while being overdressed and drawing a huge crowd... generally on a regular rotating basis of about every seven years...

NO worries Mr. Kev.................

We'll start intense therapy for your afflictions as soon as we arrive in ABQ. You should be cured (at least temporarily) by the time the rally ends!
