Item Overview for Blackmer GNX2.5A/4/1R/C0/1/4/3/0/0/0/0/N/RXXXX/PO
The Blackmer GNX2.5A/4/1R/C0/1/4/3/0/0/0/0/N/RXXXX/PO is a 2.5" alignment-free, high-speed sliding vane pump made for portable and stationary industrial transfer applications. It moves product at rates up to 155 GPM while keeping pressure consistent. A single-ended keyed shaft turning right-hand drives Duravane vanes that adjust automatically and preserve capacity over a long service life. Mechanical seals and PTFE elastomers guard the drive end against leakage and swelling. NPT connections tie the unit into existing piping without custom adapters. 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. 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.
