Item Overview for Blackmer XLW3F
The Blackmer XLW3F pairs 3" ductile iron construction with a base-mounted sliding vane pump layout suited to industrial process transfer. As part of the XLW lineup, it shares parts and service procedures with the rest of the range. Rated for flows reaching 85 GPM, it holds output steady as line conditions shift. The drivetrain pairs a hardened keyed shaft with hardened iron vanes, keeping volumetric efficiency stable between rebuilds. Mechanical seals work alongside FKM elastomers to contain aggressive media and resist chemical attack. Installation stays simple thanks to NPT connections that match common piping practice. An internal relief valve protects the system from damaging pressure spikes. The bare-shaft build lets integrators match an existing drive or specify a new one. Straightforward porting simplifies retrofits into piping already in place.
