Item Overview for Blackmer GNX2.5A/4/1R/C0/1/4/2/0/0/0/0/N/R0265-210TC/MT/N15/RXXXX/S215TC/MTRB/XP808151
The Blackmer GNX2.5A/4/1R/C0/1/4/2/0/0/0/0/N/R0265-210TC/MT/N15/RXXXX/S215TC/MTRB/XP808151 is a 2.5" alignment-free, high-speed sliding vane pump finished in heavy-duty construction. Hazardous-area duty is covered by ATEX approval for IIB gas atmospheres with a T4 temperature class. As part of the GNX lineup, it shares parts and service procedures with the rest of the range. Capacity extends to 155 GPM, shortening load and unload cycles. The drivetrain pairs a single-ended keyed shaft turning right-hand with Duravane 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. Overpressure protection arrives built in, with an internal relief valve shielding the casing and downstream piping. It ships as a complete drive package with N15 unit mounting and a factory-mounted motor, ready to set in place and connect.
