The John Blue 8B-1H pump is engineered for precise liquid fertilizer application, featuring eight rows with 3/8-inch metering hoses. It offers a rate range of 1.5 to 25 gallons per acre (GPA) and includes a 3/8-inch discharge hose and a 1-1/4-inch female NPT suction hose port. The pump's oval-shaped tubes with built-in backing plates ensure accurate metering, while the positive shut-off mechanism prevents leakage when the pump is not in operation. Designed for durability, it boasts a sturdy all-metal frame and heavy-duty PVC manifolds suitable for various fertilizers, including acid-based products. The pump shaft allows for drive connections on either side, and the rubber-coated rollers are easily replaceable in the field, with non-metallic surfaces that resist corrosion and abrasion. Multiple-coned sprockets come standard, providing seven different delivery rates to accommodate diverse application needs.
