Blackmer extends range of sliding vane pumps

Blackmer has extended its XLW Series of sliding vane pumps, introduced in 1978, with a new 4" model.

The XLW4A model, like all XLW Series pumps, has been 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.

As with all XLW Series pumps, the XLW4A model features hardened rotor and shaft, liner, end discs and vanes for long life 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 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 149ºC.
