Iwaki Metering Pump LKN47A-VH with Baldor-Reliance 0.33HP Motor

The Iwaki LKN47A-VH is a robust motor-driven metering pump designed for precise chemical dosing in industrial applications such as water treatment, chemical processing, and wastewater management. This model features a mechanically actuated diaphragm for reliable, leak-free operation, offering a maximum flow rate of 31.8 gallons per hour (GPH) at pressures up to 120 PSI. Paired with a Baldor-Reliance 0.33HP electric motor (SPEC 34M354-50761), it provides consistent performance with a stroke rate of 116 SPM and operates on 115/230V, 60Hz power. Key benefits include high accuracy (±1% repeatability), corrosion-resistant materials in the VH head (likely PVC with Viton seals for chemical compatibility), and adjustable stroke length for fine-tuned dosing. Compared to similar pumps like those from Pulsafeeder or Milton Roy, the Iwaki LK series excels in durability and ease of maintenance, with a compact design suitable for tight spaces. Drawbacks may include higher initial cost and the need for regular diaphragm checks in aggressive media. This unit appears used but in good condition, with visible wear on the motor housing but intact labels and no major damage. No parent/child assets noted beyond the integrated motor and basic fittings.
