Blackmer”s X and GX Series Sliding Vane Pumps have been designed with a variety of features that make them a good fit for the loading, transfer and unloading of solvents used in paint & coatings manufacturing applications. Solvents, also known as the carrier, are the portion of the paint that helps get the pigment and binder from the container onto the surface that is to be painted. What separates the GX Series pumps — which are available in four different models with flow rates ranging from 30 and 520 GPM (114 and 1,855 LPM) — from the X Series models is the incorporation of an integral head-mounted gear-reduction drive that features oil-lubricated, hardened helical gears. The gear shafts are supported at both ends by ball bearings for smooth operation and long life. A splined reducer, which can be rotated on the pump head to accommodate a variety of motor sizes, simplifies pump and reducer alignment. Both the GX and X Series pumps — which are also available in 2-, 2.5-, 3- and 4-inch port sizes with the same flowrate range as the GX models — are constructed of cast iron and offer self-priming and dry-run capabilities. Their symmetrical bearing support assures even loading and wear for long life, while an adjustable relief valve protects the pump against excessive pressures. The pumps also feature a sliding-vane design that self-adjusts for wear to maintain flowrates and ease maintenance. –
