Pulsafeeder Pulsa Series Diaphragm Metering Pump

The Pulsafeeder Pulsa Series Diaphragm Metering Pump is a durable, positive displacement pump designed for accurate chemical dosing and fluid transfer in industrial settings, including water treatment, chemical processing, petrochemical, and pharmaceutical applications. It utilizes a hydraulically balanced diaphragm to prevent leaks and handle corrosive or viscous fluids effectively, offering precise flow control through adjustable stroke length via a manual knob. Key features include a robust gear-driven mechanism, integrated stroke counter for monitoring, and threaded connections for easy installation. Advantages over similar products include high pressure tolerance, reliable performance in harsh environments, and low maintenance requirements due to its sealed design. Drawbacks may include the need for periodic gear box lubrication and a heavier build compared to peristaltic pumps. This model excels in applications requiring consistent metering under variable conditions, providing better accuracy and longevity than basic piston pumps. Based on image analysis, this unit appears used with some internal rust and wear, but functional internals suggest it could be refurbished for continued use.
