Blackmer has announced the availability of the XLW4A Model Sliding Vane Pump. The 4 in. pump is an extension of Blackmer’s XLW Series Sliding Vane Pump line, which was introduced in 1978.
XLW Series pumps have been designed to perform in the handling and transfer of abrasive liquids, including oxide primers, inks and paints, where wear-resistance is critical to pump operation. XLW Series pumps have also shown to be successful in applications such as vertical and horizontal bead mills, solvent recovery, tank bottom recirculation, heat treater supply, enhanced oil recovery, and crude or hot oil transfer.
The XLW4A model features hardened rotor and shaft, liner, end discs and vanes for longlife and optimised wear resistance. These hardened internal parts allow the pump to be used with liquids featuring suspended abrasive particles up to 250 microns in size and a concentration up to 25%. It can produce flow rates up to 190 gpm (719 ltr/min) at speeds up to 350 rpm; handle viscosities to 20 000 SSU (4250 cSt); operate at differential pressures to 150 psi (10.3 bar) and working pressures up to 350 psi (24.1 bar); and handle temperatures up to 300 °F (149 °C).
