Item Overview for Blackmer X4B-N
The Blackmer X4B-N is a single-ended, high-speed sliding vane pump built in ductile iron construction for high-capacity transfer in bulk plant service, aircraft refueling, and large-scale industrial operations. Containment comes from mechanical seals backed by FKM elastomers, a combination chosen for punishing liquids. NPT connections speed connection during commissioning and later service. Overpressure protection arrives built in, with an internal relief valve shielding the casing and downstream piping. Supplied as a bare unit, it drops into an existing drive arrangement or a purpose-built skid. 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. Capacity extends to 528 GPM, shortening load and unload cycles. 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.
