For 120 years, Blackmer® has upheld a legacy of unmatched product performance, exceptional service, innovation, and unwavering dedication to customer satisfaction. Founded in Petoskey, Michigan in 1899 and later relocating to Grand Rapids in 1925, our commitment extends to people, partners, and products. Through pioneering technologies, Blackmer consistently exceeds expectations, notably with our vane-type pump design introduced by R. M. Blackmer in 1899—a groundbreaking departure from traditional gear pumps. Unlike gear pumps, our vane-type pumps demonstrate minimal loss over time, offering sustained performance and self-adjusting capabilities as vanes wear, ensuring a consistent flow rate.
