Blackmer® Extends GNX Series Pumps Due to High Customer Demand

DOWNERS GROVE, Ill., July 16, 2019 /PRNewswire/ -- Blackmer®, part of PSG® and Dover (NYSE: DOV), and a global leader in specialty pumps and reciprocating compressor technologies, is pleased to announce that its GNX Series Sliding Vane Pumps are now available in 3- and 4-inch models. Due to increased customer demand, Blackmer has doubled the models available in its popular GNX Series, the market’s only alignment-free reduced-speed positive displacement pump.

“When we launched the Blackmer GNX Series in 2017, even though the product line was limited to just the 2- and 2.5-inch models, it quickly began surpassing sales expectations,” said Geoff VanLeeuwen, Product Management Director for Blackmer. “This significant increase in customer demand can be attributed to GNX Series’ one-of-a-kind construction, which features zero-alignment design that offers our customers several benefits, such as ease of installation, lower maintenance and increased reliability. Now that we have added 3- and 4-inch models to the product line, there’s no doubt that this product line will continue to resonate in the marketplace for years to come.”

Blackmer GNX Series pumps have been designed to optimize the transfer of non-corrosive, non-abrasive industrial and petroleum products for both portable and stationary applications. These heavy-duty sliding vane pumps include the proven features of Blackmer legacy GX Series pumps but take them to the next level with the incorporation of a commercial-grade, single-stage gearbox, motor and baseplate. This innovative new gearbox fits between the motor and pump and is held in place by a permanent dowelled connection that creates a structural link between the high-speed and low-speed sides of the system. This results in a pump that will not need to be realigned either at initial installation or following a maintenance procedure, resulting in improved peace of mind for the operator.

To further highlight the GNX Series’ innovative design, Blackmer has developed an interactive web tool that illustrates the pump’s working principle while emphasizing key design elements that help the GNX Series separate itself from the competition.
