The best Shurflo

[deitzd]

I'm already looking forward to next season and planning improvements. There's a lot of great information on here about shurflo pumps. I have plans for 50-100 taps on twin 1/2" mainlines coming to a common manifold and I want to use a shurflo pump for vacuum. I can power it with either 12 volts or 120 volts. Which shurflo pump would be best for this situation?

I use 4008's. I have 170 taps on 3/4" main line and pull 15" to 17" of vacuum consistently. I have 5 pipelines all running 4008's on 12 volts. Never had one issue this season, besides a couple vacuum leaks. They saved my season this year.

I think most Shurflo will treat you fine, I bough a 2088 model because the specs said 3.5 GPM and 5 amp, the diaphragm I think is "Neoprene" a bit different from the 4088 I believe.

Whatever you buy be sure to get the debris/ice filter for Shurflo pumps, money well spent.

You will love the difference these pumps make, mine is running as I type, lol.

I'm interested in feedback from anyone who has run both 12v and AC. I have considered both, but prefer to run AC to avoid dealing with a battery. Are there advantages or disadvantages for either?

My understanding is that the DC pumps will last a lot longer. The motor will, anyway. I guess the AC ones have a life expectancy of around 1000 hours, where the DC ones are more like 4-5000.

I yanked a power supply out of an old PC computer. Googled which wires to cut and had a free AC to DC power converter in about 15 minutes, including taking the computer apart.

I agree with motowbrowne. My 2088 quit two weeks into this season after using it last year. Fortunately, I had a spare on hand I planned to use as a transfer pump. Can rebuild it with replacement brush kit is $40, but can get a new pump for $70. I like the PC power supply idea and will be looking into that for next season.
