Item Overview for Blackmer GNX2.5A/4/1R/C0/1/4/2/0/0/0/0/A/R0215-210TC/PO
The Blackmer GNX2.5A/4/1R/C0/1/4/2/0/0/0/0/A/R0215-210TC/PO pairs 2.5" rugged construction with an alignment-free, high-speed sliding vane pump layout suited to portable and stationary industrial transfer applications. ANSI Class 150 raised-face flanges 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. 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. Rated for flows reaching 155 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.
