Blackmer’s 4 in XLW4A sliding vane pump has 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. The pump's hardened rotor and shaft, liner, end discs allow the pump to be used with liquids which have suspended abrasive particles up to 250 microns in size and at a concentration up to 25%. The XLW4A pump is designed to 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).
