March 16, 2010

Blackmer XLW Series of sliding vane pumps have been designed to handle liquids with suspended particles up to 250 microns and 25% concentration, such as paint, adhesives and inks. XLW Series pumps are designed with hardened ductile iron materials, giving the pump the unique capability of easily handing abrasive liquids. Available with O-rings, mechanical seals, relief valves, springs, vanes and rotors, the XLW pumps may be fitted to handle a wide variety of materials. Base mounted unit assemblies with a helical gear reduction drive are available for all XLW models. XLW pumps are available in 2- and 3-inch port sizes and are available in flanged ports with NPT, weld, ANSI and DIN options. The XLW Series pumps offer flow rates between 6 gpm and 85 gpm (23 to 320 lpm) with differential pressures to 150 psi (10.34 bar). The pumps provide excellent self-priming and dry run capabilities, and include an adjustable relief valve that protects the pump against excessive pressures. The XLW Series positive displacement rotary pumps offer the best combined characteristics of sustained high-level performance, energy efficiency, trouble-free operation and low maintenance cost, according to the company.
