Item Overview for Blackmer GNXH3A
The Blackmer GNXH3A is a sliding vane pump configured for portable and stationary industrial transfer applications. Supplied as a bare unit, it drops into an existing drive arrangement or a purpose-built skid. As part of the GNX lineup, it shares parts and service procedures with the rest of the range. It moves product at rates up to 275 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 FKM 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.
