Liquefied gas pumps specially
designed for liquid CO2 service
in response to specific requests from major CO2
marketers for a more durable pumps, 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.
Design criteria included the ability to easily handle
dry, non lubricating CO2
at sub-zero temperatures, with differential pressures
up to 100 psig (689 kPa) while operating on a continuous
24-hour duty cycle with minimal manitenance and inspection
After four years of intensive research and development,
and 30,000 hours of combined laboratory and field
testing, Blackmer introduced a new line of pumps that
far exceeded the original expectations.
