  1. what does on demand mean?

    What does the bypass mean on some of the pumps? If i were to use it for spraying weeds should i get one with a bypass? Than you for your toime

    1. I think 'on demand' and 'bypass' are 2 different things. "On demand' means the pump shuts off once the shutoff pressure is reached, like 80-90psi on the model listed (I have this pump). Once the pressure drops, by like opening a valve or a handheld wand, the pump turns on and begins to flow liquid at a reduced pressure, which is set by the flow area (flowing thru a series of nozzles or open flow) and the pressure setting of the pump. Mine flows at about 40psi with 4 blue or red nozzles (1.2-1.6gpm). "Bypass" refers to a internal circuit inside the pump that will allow the pump to not cycle rapidly on and off at low flow rates. The pump I have (same one you are questioning) will cycle rapidly if I have the flow rate below 1.2gpm (like using 4 green nozzles or 4 yellow nozzles). The bypass recirculates some flow from the discharge of the pump back to the inlet of the pump to keep the flow rate high enough to avoid cycling. I don't believe this pump is a bypass model.

      Helpful?

    2. On demand means that the pump has a pressure switch on it. If your sprayer is off (not spraying) the pump will continue to run until a set pressure is achieved. On this pump it is 60 lbs. At that pressure, the pump will turn off. There will be 60 lbs of pressure in the output hose to your sprayer handle. When you open the spray valve, the pump will turn on. This saves wear and tear on the pump.

      Helpful?

    3. This pump features an on demand switch that automatically turns the pump on and off as flow is required (pulling the spray trigger). The bypass feature circulates the water in the pump until demand is required.

      Helpful?

  2. Can this Pump be used to only move Air? Also what is the noise level given off by this pump?

    1. The noise level is low.

      Helpful?

    2. This pump cannot be used to move only air. There is no official decibel rating on this pump. It is however a very quiet pump that is quieter than normal speech.

      Helpful?

  3. Dose this pump pulsate

    or dose it have steady flow. How high will spray?

    1. The pump has a steady spray when used with my 15 gallon sprayer.

      Helpful?

    2. This pump delivers a steady flow rate, and the manufacturer does not have a spray height rating available for this pump.

      Helpful?

  4. Can this pump -pump salt brine ?

    1. Yes, but flush out after use. That heavy of salt content, will affect the rubber diaphragm much faster than normal.

      Helpful?

    2. This diaphragm pump can be used to transfer salt brine. It's recommended to flush the pump with water afterwards.

      Helpful?

  5. Does this pump have a built in check valve

    1. yes

      Helpful?

    2. This pump does have a built in check valve.

      Helpful?

  6. Will this unit pump used motor oil?

    1. This pump is not designed to pump oil or any other hydrocarbon, Shureflo makes that clear in the literature that comes with the unit, the internals of the pump are plastic and rubber so I doubt they would stand up to oil for very long.

      Helpful?

    2. This Shurflo on demand pump will not pump used motor oil.

      Helpful?

  7. what (110v to 12v) power supply can I use with this water pump?

    1. 12 volt

      Helpful?

    2. At Northern Tool we do not sell any 110 volt to 12 volt power supplies that can be used to power this pump.

      Helpful?

  8. Is the pump temporarlily (1 day) submersible - 2 feet?

    1. No

      Helpful?

    2. No, this pump cannot be submersed.

      Helpful?

  9. What are the dimensions (DISTANCE) of the base plate screw holes

    1 answer

    1. The mounting pattern is 2 1/4" x 3 1/8" center to center.

      Helpful?

  10. Is this pump a proper replacement for a North Star 2272

    1 answer

    1. The direct replacement for the 2272Q pump is item 2682272. Item 6053154 is a suitable alternative.
