Item Overview for Blackmer GNX2.5A/4/1R/AZ/1/4/3/0/0/0/0/W/R0265-180TC/PO
The Blackmer GNX2.5A/4/1R/AZ/1/4/3/0/0/0/0/W/R0265-180TC/PO brings alignment-free, high-speed sliding vane pump construction to portable and stationary industrial transfer applications. 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 PTFE elastomers, a combination chosen for punishing liquids. Weld 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. Throughput climbs to 155 GPM, giving operations headroom during peak transfer windows.
