  • Bio pump

    Hi all , new to the forum , starting to build my processor and would like to know your ideas on pumps .
    Can a domestic water pump handle veg oil and bio diesel or do I need to get something special ?
    Prefer 240v .

    Dero,
    When I made biodiesel some years ago, I used a single phase water pump to mix the oil and methoxide. It ran well and had no issues in 12 months, then I went back to straight veggie oil blended with ULP.
    Life is a journey, with problems to solve, lessons to learn, but most of all, experiences to enjoy.

    Current Vehicles in stable:
    '06 Musso Sports 4X4 Manual Crew Cab tray back.
    '04 Rexton 4X4 Automatic SUV
    '2014 Toyota Prius (on ULP) - Wife's car

    Previous Vehicles:
    '90 Mazda Capella. (2000 - 2003) My first Fatmobile. Converted to fun on veggie oil with a 2 tank setup.
    '80 Mercedes 300D. 2 tank conversion [Sold]
    '84 Mercedes 300D. 1 tank, no conversion. Replaced engine with rebuilt OM617A turbodiesel engine. Finally had good power. Engine donor for W123 coupe. (body parted out and carcass sold for scrap.)
    '85 Mercedes Benz W123 300CD Turbodiesel
    '99 Mercedes W202 C250 Turbodiesel (my darling Wife's car)[sold]
    '98 Mercedes W202 C250 Turbodiesel (my car)[sold]
    '06 Musso Sports Crew Cab well body. [Head gasket blew!]
    '04 Rexton SUV 2.9L Turbodiesel same as Musso - Our Family car.
    '06 Musso sports Crew Cab Trayback - My hack (no air cond, no heater).

      I am currently using a 240v pump from a dishwasher. They are not high capacity but is a reliable transfer pump for the past 2 years. It is a paddle type pump, most water pumps are an centrifugal impeller pump that will move 1000 litres pretty quick. Dishwasher pump takes 30 minutes to move 160 litres to my headder tank aprox 2.5 m high.

        I have ended up using both a pump and paint stirrer in a drill. I eventually started using the pump because I already own it. It is an Orange regenerative turbine pump about 30 years old. Very neglected and just keeps running. After the initial thorough mix with the paint stirrer, every 10- 15 minutes I come out and run the drill paint mixer again to insure nothing is settling out on the bottom. The pump runs for the full hour
        For most of my time making biodiesel, I just used a drill mixer.
