Banjo M300PO is the 3" manifold-flange polypropylene self-priming centrifugal pump end with 3/4" shaft and 4-vane trimmed impeller, sold without a drive. It's the replacement pump for Banjo M300 series manifold pumps on large sprayers, nurse trailers and fertilizer tenders — the 300 series flange clamps straight into Banjo's no-thread manifold system, so swapping the pump end takes minutes, not an afternoon of fighting 3" pipe threads. Bolts to your existing gas engine, hydraulic motor or electric motor.
In stock at our Spokane, WA shop and ships same or next business day. Call us with your pump or engine model if you want to confirm fit before ordering.
What it's for
Water, liquid fertilizer and most crop-protection chemicals. Glass-filled polypropylene body and volute, EPDM check valve and o-rings, mechanical shaft seal. Not for petroleum products or solvents.
