Item Overview for Blackmer CRLR1.25/5/CL/BT/1/B/1/0/0/0/0/0/0/PO
The Blackmer CRLR1.25/5/CL/BT/1/B/1/0/0/0/0/0/0/PO is a 1.25" ductile iron sliding vane pump made for loop systems and low volume transfer applications. It moves product at rates up to 11 GPM while keeping pressure consistent. The drivetrain pairs a four-vane rotor turning left-hand with laminate vanes, keeping volumetric efficiency stable between rebuilds. Mechanical seals work alongside Buna-N elastomers to contain aggressive media and resist chemical attack. Installation stays simple thanks to tapped ports that match common piping practice. 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 CRL lineup, it shares parts and service procedures with the rest of the range.
