Blackmer CRL1.5-PO 1.5″ High-Speed Sliding Vane Pump – Liquid CO₂ Service
Heavy-duty Blackmer CRL1.5-PO Coro-Vane/sliding vane pump engineered for liquefied carbon dioxide handling, recirculation and low-volume transfer applications.
This pump features a rugged ductile-iron construction, 1.5-inch tapped NPT inlet and outlet connections, single-ended keyed shaft configured for right-hand rotation, external ball bearings and an integral adjustable relief valve.
The mechanical seal configuration uses a carbon stationary seat, silicon-carbide seal face and special EPDM stationary/rotating O-rings, per the specified CRL1.5-PO configuration.
Blackmer’s published CRL1.5 specifications give a nominal capacity of 5–24 GPM, maximum differential pressure of 100 PSI, maximum allowable working pressure of 525 PSI, and operating speed range of approximately 750–1,150 RPM.
PUMP ONLY – motor, coupling, baseplate and other drive components are not included.
