Thread: Why does this Shurflo pump seem so great? Will it work for my house with my EU2000i?

    Default Why does this Shurflo pump seem so great? Will it work for my house with my EU2000i?

    Searching through this forum I found a Shurflo water pump http://www.solar-electric.com/2088-594-154.html
    This pump seems like it will work for me. I currently am using a 1/2HP pump to take water from my cistern and pump it up to my house. My pump sits outside of the cistern at the bottom. The cistern is about 20’ lower than the top of the house. Pipes are ” and we only take one shower at a time. There is a 20 or 40 gallon pressure tank connected near the pump. The pressure is 60psi off and 20 on. 45-50 psi off would be great but I would like the on pressure set at 30.

    My current pump will not work with my Honda EU2000i. I was able to get the pump to start a few times from the generator but I had to plug it directly into the generator and start the generator with it connected. If the generator was on when the pump tried to start it wouldn’t work.

    This Shurflo pump seems to draw so little current. Its flow would be about 2 GPM. Would this be enough? Is there another model that could provide 3GPM at 30PSI?

    What kind of maintenance am I looking at for a pump like this?

    Perhaps you should consider a 12 volt pump such as: http://www.solar-electric.com/5904-1211.html
    You can power it from your generator using this: http://www.solar-electric.com/ioen12vo15am.html
    This extreme sensor pump needs no pressure tank.

    Another possibility is to use a lower capacity 12 volt pump such as: http://www.solar-electric.com/8000-443-136.html which, I believe can be powered directly by the 12 volt output of the honda eu2000 generator.

    An advantage of using a 12 volt pump is that someday you can set up a modest solar system that will power the pump, and free yourself from the generator.

    Jeff the specs for that pump are
    PSI 10 20 30 40
    BAR .7 1.4 2.1 2.8
    GPM 2.6 2.34 2.08 1.85
    L/MIN 9.8 8.8 7.9 6.2
    AMPS .58 .67 .76 .94

    There is no way that your 2000w gen at ~13.3 A should not be able to run the pump.. it is listed @ drawing 113 W.
    That gen puts out 2000max and 16000W continuous.

    Re the old pump: are you trying to start it in ECONO mode. My 1000 has problems with inrush if in Econo mode.

    Non submersible shurflos are good pumps. That said, they won't pull water very far. (suction side) but they will push water up to ~60 psi, so if you locate the pump at the cistern, with all the wiring loses associated with that it should work, but if you expect to ump from the cistern up 20' is won't.

    I currently am using a 1/2HP pump to take water from my cistern and pump it up to my house.
    Typical 1/2 hp submersible pump takes about 30 amps to start at 220 volts, 60 amps at 120 volts. I don't think your 2000i has that much surge power.

    Default My Honda EU2000i wont power this tiny Shurflo pump :(

    Well, I finally needed to use my Shurflo 2088-492-444 water pump. It did not work with my Honda EU2000i!

    I even made a short electrical cord of no more than 5' and pluged only it into my generator. I tried in Eco Mode and not in Eco mode. I even removed any output pressure on the pump.

    My EU2000i goes into overload in less than a second and only a few spits of water comes out. This pump runs fine on my household AC.

    Also, I can get my Honda EU2000i to start my old 1/2HP waterpump if that pump has less than 10 PSI on it. The Honda powers my microwave and in sink garbage disposal (one at a time). Everything else in the house can be run at the same time off of the EU2000i just fine.

    This doesnt make sense!

    Are you sure you have it wired right ?? Are your bringing the hot into the switched side ?? If you are breaking the ground with the switch you may have a issue ?? I don't have that exact pump, but the color code on the wiring would be easy to mix up on the one I have.

    How fast is the pump spinning at the time the inverter shuts down? If it is not anywhere near full speed, you are still in the starting surge region of its power consumption, and that may be just too much for the Honda to handle.

    According to the specification sheet (http://legacy.shurflo.com/pdf/rv/pro...88-492-144.pdf) this pump is not intended for use IN an RV but rather as a shore-side pump. As such it assumes that it will have full shore power available for starting and no effort was made to make it easy to start. (In fact, the descriptive name for it elsewhere on the site is "Park Model Pump.")
    The recommended fuse is 1 AMP time-delay which also suggests a high starting surge.

    There are threads about starting surge and ways to reduce the surge, some of which may apply to your pump, but you may be better off replacing it with a pump that is better designed for your circumstances.

    The Honda EU20001 has good surge power capabilities for an inverter model generator, but a traditional generator can often have larger surge ratings because it can suck power from the energy of the spinning "flywheel" and deliver current even as it slows down under the load.

    If the pump itself is working too hard (undersized) it will remain in start-up too long like inetdog said. In general it's not a direct replacement for a 1/2 HP centri-pump; you'd have to change a lot more (the plumbing).

    If a Honda EU 2000 won't start a pump that takes .9 amps, Honda is in trouble. I agree it has a starting surge, it still should start that pump.
