In response to specific requests from major CO2 marketers for a more durable pump, capable of handling higher working pressures on liquid CO2 service, Blackmer accepted the challenge of designing a pump that would meet or exceed the marketers' specifications. Designed for maximum performance and reliability under the most severe service conditions.

• Cavitation suppression liner design for reducing the noise, vibration, and wear normally caused by entrained vapors.
• Replaceable casing liners and end discs allow easy rebuilding of the pumping chamber to like-new condition
• Ductile iron construction with internal relief valve.
• Unique sliding-vane pump design self-adjusts for wear to maintain flow rates.
• Excellent self-priming and dry run capabilities.
• Blackmer mechanical seal and ball bearing construction provide maximum reliability
• Symmetrical bearing support assures even loading and wear for long life.
• Adjustable relief valve protects pump against excessive pressures.
• External ball bearings are isolated from pumpage by mechanical seals to maximize bearing life and minimize contamination risk.
• Easy maintenance: vanes can be easily replaced without removing the pump from the piping system.
