Blackmer introduces the XLW4A Model Sliding Vane Pump. The 4-inch pump is an extension of Blackmer’s XLW Series Sliding Vane Pump line.
XLW Series pumps are designed to perform in the handling and transfer of a variety 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, according to Blackmer.
The XLW4A model features hardened rotor and shaft, liner, end discs and vanes for long life and optimized wear-resistance. The hardened internal parts allow the pump to be used with liquids featuring suspended abrasive particles up to 250 microns in size and at a concentration up to 25%.
The XLW4A model can produce flow rates up to 190 gpm (719 L/min) at speeds to 350 rpm; handle viscosities to 20,000 SSU (4,250 cSt); operate at differential pressures to 150 psi (10.3 bar) and working pressures to 350 psi (24.1 bar); and handle temperatures up to 300ºF (149ºC).
