The John Blue 8B-1 Squeeze Tube Pump is engineered for precise liquid fertilizer application, featuring oval-shaped tubes with built-in backing plates to ensure accurate metering. Its positive shut-off mechanism prevents leakage when the pump is not in operation. The pump accommodates 8 rows, each with a 3/8-inch metering hose, and offers a rate range of 1.5 to 25 gallons per acre (GPA). The discharge and suction hose sizes are 3/8-inch and 1-1/4-inch FNPT, respectively. Designed for durability, it includes sealed-for-life bearings that require no lubrication and a heavy-duty PVC manifold suitable for various fertilizers, including acid-based products. The pump shaft allows for drive from either side, and rubber-coated rollers are easily replaceable in the field. Multiple-coned sprockets come standard, enabling seven different delivery rates. The sturdy, all-metal frame ensures long-lasting performance in demanding agricultural environments.
