    Default Maxant Honey Pump

    Does anyone have personal experience with the flow rate (GPM) on the 1" Maxant Honey Pump?

    depends on rpm and distance to pump,, call maxant, give them what you have and listen to their recommendations,,

    I am a dealer for Maxant and talked to them. Bottom line, they don't know. No flies on Maxant. They are really good about standing behind their products. They say the pump will only pump 1 GPM. That is based on recollection of a calculation done 40 years ago by someone who is no longer in the picture. They have no anecdotal information from actual users. My motor RPM/pump output capacity/pulley size calculations indicate 6.86 GPM with a 1 HP motor. They are using an underpowered 1/3 HP HVAC blower motor but they are using a double jack pulley system. Even with the undersized motor the pump ought to do 2+ gallons a minute. The only anecdotal information I have from actual users is 1.6 GPM pumping under heavy load through an in-line filter and 2 to 2.5 GPM in a hot honey room, high moisture honey, low load situation. I am hoping someone else using the Maxant pump will post their experience.

    At 85 degrees F right out of the sump my maxant will pump about 3.5-4 gal per minute.

    Thanks for the reply THALL. That's more than I (or Maxant) thought it would do. I'm wondering about the following specifics:

    1) Are you running 1" lines all the way or close nippling on both sides of the pump and running 1-1/2" or 2" lines?
    2) What is the average moisture level of the honey you are pumping?
    3) How high are you having to pump it vertically into your tanks?
    4) How do you have your pump anchored to the floor (not at all, lagged into the slab, blocked in but not lagged, etc.)
    5) How are you uncapping (some of the guys using chain uncappers get slower rates due to the real small wax bits that get past the sump)?

    I am not familiar with this exact pump but I have been researching these pump beads. The potential performance is greatly affected by:
    Required lift-always try tokeep the pump lower than the supply or "charge" the supply side witbwith a pusher pump-maybe a hand version. The viscosity/weight is the real problem.
    Run at the proper rpm so the liquid does not cavitate inside the pump. The thicker the fluid and or the higher the lift the lower the rpm needed. If this pump is a true 1" gear pump I would think a 1 1/2 HP pump would providea lot more volume than what has been posted.

    I used these pumps on high viscous water based conductive adhesives.

    The whole issue with pumping viscous materials is getting the material to the push side of the pump. If you can successfully do that than you can push it anywhere with just horsepower. These pumps are food grade easy to clean and keep clean but I don't suspect that there are many used in the honey industry because of their cost. However, they are well suited for the application.
    These pumps were the only pump design that was capable of doing the job for adhesives because of their low shear action.

    I am just curious but has anyone measured the viscosity of honey before and after it has been pumped? I suppose thinning the honey down is not a negative for most consumers.

    I hope your statement contains at least one typo...


    Unless you're referring to the warming of the honey by the pump. That would not be considered thinning by many imo.

    No I mean thinning down by mechanical shear. Nothing is added (like water). If you were to compare the viscosity before pumping and after pumping it would have to be at the same temperature to make a true comparison.

    Thinning by shear would suggest to me, and remember I am by no means any authority on pumps, that cavitation is taking place no? The only other way it could be thinned by shear would be due to heat caused by friction-again a guess??

    In speaking with an engineer at a large pump manufacturing company it was explained to me that the problem with pumping high viscosity liquids, as you suggest, is getting the liquid to the push side BUT I was also told that a gear pump, in a high viscosity application, will have trouble lifting the liquid (head???). This person was very helpful & informative and thought the gear pump would be helped greatly with some sort of pusher pump or having the liquid supply placed level with, or above, the pump inlet. He also said that cavitation is large issue in determining the pump size and rpm.

    Thanks
