Liquid CO2 Loading and Unloading Pumps

BIG GROUP Liquid Carbon Dioxide - Loading & Unloading Pumps provide critical flow solutions.
A specialised kind of Cryogenic pumps rae used for Loading & Unloading of the Liquid Carbon dioxide content from lorry mounted vehicles to CO2 storage tank or Vice – Versa.
Industrial & Process Sliding Vane Pumps
The Liquid Carbon di oxide being cryogenic in nature could not be handled through naked hand, and become very difficult to handle & manage. BIG Group pumps are available in compatible materials with shaft sealing and seal-less options that make them the products of choice for many process applications.
