Item Overview for Blackmer X2B
The Blackmer X2B pairs 2" cast iron construction with a single-ended, high-speed sliding vane pump layout suited to fast, quiet operation in bulk plant service, aircraft refueling, and underground tank pumping. NPT connections speed connection during commissioning and later service. 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. It also brings extended dry-run capability. As part of the X lineup, it shares parts and service procedures with the rest of the range. Rated for flows reaching 82 GPM, it holds output steady as line conditions shift. Power reaches the pumping chamber through a single-ended keyed shaft turning right-hand, where Duravane vanes ride out against the liner to sustain flow as they wear. Containment comes from mechanical seals backed by FKM elastomers, a combination chosen for punishing liquids.
