Vane Pumps Pumping Carrier Solvents for Paints and Coatings
Loading, transferring and unloading of solvents is where Blackmer's new X and GX Series Sliding Vane Pumps feel right at home. Especially the processing of 'carrier' solvents in Paint & Coatings manufacturing applications is a typical task for the its new units, the company says.
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) – feature also a an integral head-mounted gear-reduction drive with 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 flow-rate range as the GX models—are constructed of cast iron and offer good self-priming and dry-run capabilities, Blackmer states. Their symmetrical bearing support assures even loading and wear for long life, while an adjustable relief valve protects the pump against excessive pressures. As the GX pumps, also these units benefit from Blackmer’s sliding-vane design that self-adjusts for wear to maintain flow rates and ease maintenance.
