CRL Series High-Speed Sliding Vane Pumps

Blackmer CRL Series high-speed sliding vane pumps are ductile iron recirculation pumps built for liquefied carbon dioxide service. Part of Blackmer's Cavitation Line, they deliver 5 to 22 U.S. gpm (19 to 83 L/min) and are designed for foot mounting to a common baseplate, which makes them well suited to loop systems and low volume transfer. Every model in this series carries a cavitation suppression liner that reduces the noise, vibration and wear normally caused by entrained vapors, along with a replaceable casing liner and end discs that let the pumping chamber be rebuilt to like-new condition. External ball bearings are isolated from the pumpage by mechanical seals to maximize bearing life, and symmetrical bearing support spreads loading evenly across the shaft. An adjustable integral relief valve protects the pump against excessive pressure, and vanes can be replaced without pulling the pump out of the piping. Available Models Model Port Size Nominal Flow Range Maximum Differential Pressure Shipping Weight CRLR1.25 1.25 in NPT 2.5 to 11 gpm (9 to 42 L/min) 70 psi (4.83 bar) 32 lb (15 kg) CRL1.25 1.25 in NPT 2 to 15 gpm (8 to 57 L/min) 100 psi (6.9 bar) 32 lb (15 kg) CRL1.5 1.5 in NPT 5 to 24 gpm (19 to 91 L/min) 100 psi (6.9 bar) 32 lb (15 kg) The CRLR1.25 uses a special liner that gives it lower flow rates than the CRL1.25, so the two models share a port size but are not interchangeable. All three models share the same envelope dimensions and the same shipping weight. Rotation Rotation is selected above and is available at no additional cost on every model. It is viewed from the driven end of the pump: Right Hand (CW), code CR. Inlet is to the right when looking from the driven side. This is the standard build. Left Hand (CCW), code CL. Inlet is to the left when looking from the driven side. Choose the direction that matches the driver you intend to couple the pump to. Both directions use the same four vane rotor and carry the same price. Standard Configuration Beyond model and rotation, this series ships in one standard configuration. Every pump on this page is built with the following: Item Standard Build Code Vanes Laminate 5 Rotor Four vane, single-ended keyed shaft CR or CL Mechanical Seal Carbon / EPDM / Silicon Carbide / EPDM (CELE) BT Relief Valve Integral, adjustable 1 Relief Valve Spring Steel, 81 to 125 psi B O-Rings Buna-N 1 Standard Construction Fields Standard 0000 Flanges Tapped NPT ports 0 Accessories None 0 Specifications Specification Value Maximum Allowable Working Pressure 525 psi (36.2 bar) Viscosity Range 0.2 to 4,250 cP Temperature Range -30°F to 240°F (-34°C to 115°C) Speed Range 750 to 1,150 rpm Primary Material Ductile iron Connection Orientation Side inlet, side outlet, 180° inline porting Connections NPT tapped ports Vane Material Laminate, rated -30°F to 240°F (-34°C to 115°C) Elastomer Buna-N, rated -25°F to 240°F (-34°C to 115°C) Sealing Blackmer single mechanical seal Dimensions All three models share one envelope. Blackmer's dimensional data gives the pump-only weight as 29 lb (13 kg); the 32 lb (15 kg) figure shown in the model table above is the shipping weight and is what applies to freight.

Call (262) 646-4500 and we will quote the exact build. Option Details Integrated Unit Assembly Direct mount package including base, coupling and steel guard, ready to receive pump and motor. Ratio code R0100, available for 182T, 184T, 213T and 215T motor frames. Maximum motor speed 1200 rpm. Pump and motor are priced separately. Fully Integrated Unit Assembly Factory assembled package including motor, gearbox, baseplate, coupling and safety covers, supplied ready for drop-in installation with no field alignment required. Alignment Free Accessories 2 in and 2.5 in alignment free mounting accessories are available across the CRL, GNX, GNXH, SGL, XL and XLW families. Certificates Hydrostatic test, performance test, NPSH test, material certification (actual or typical) and dimensional certification (pump only or unit) are available on request at time of order. Maintenance Kits Each model has its own maintenance kit and rebuild kit. The maintenance kit covers routine wear items; the rebuild kit restores the pumping chamber to like-new condition. Model Maintenance Kit Rebuild Kit CRLR1.25 898902 899002 CRL1.25 898903 899003 CRL1.5 898904 899004 Kits are model specific. If you are not sure which model you have, call (262) 646-4500 with the serial number from the pump nameplate and we will confirm the right kit before you order. Replacement Parts Individual wear parts are stocked so a single vane or seal can be replaced without buying a full kit.
