New Blackmer® Sliding Vane Pump Delivers Superior Performance and Reliability for LPG Bobtails and Transports

DOWNERS GROVE, Ill., June 9, 2021 /PRNewswire/ – Blackmer, part of PSG, a Dover (NYSE: DOV) company, and a global leader in specialty pumps and reciprocating compressor technologies, is pleased to announce the availability of its new sliding vane pump. This new product, called the Blackmer TLGLF3HD, is a flange-mounted truck pump designed to further increase pump reliability and safety, while optimizing the loading and unloading speeds of liquid petroleum gas (LPG) products for bobtails and transport trucks.

The new TLGLF3HD sliding vane pump is designed with state-of-the-art self-adjusting vanes that can sustain fast load times, unmatched by other pump technologies that suffer from internal wear and time-wasting slip. The TLGLF3HD also features a higher flow rate, increasing the amount of liquid that travels through the pump in a given time by 55% compared to previous 3-inch Blackmer truck pump models. This higher flow rate makes the TLGLF3HD an ideal solution for high-capacity bobtails handling high-volume deliveries to residential farms and commercial customers.

The TLGLF3HD is directly coupled to the tank, without additional pipe and fittings between tank and pump. This has smoother operation, maximizing performance and reliability.

"Blackmer originated the first truck-mounted pump in 1915 and has continued to develop innovative pumping solutions ever since," said Chris Hordyk, Blackmer Product Manager. "Not only does the new TLGLF3HD decrease LPG loading and unloading times, which means less wear and tear on the equipment, it also sets the standard for sustained high-level performance, energy efficiency, and trouble-free operation. This makes the TLGLF3HD the go-to choice for LPG transport truck builders and propane marketers for truck-mounted pumps."
