Removable (In-Tank) Pumps are used for product send-out or the emergency off-loading of cryogenic liquids from a storage tank. This pump is installed into the storage tank at the lower end of a discharge column. By application of a positive pressure, inert gas purge to the discharge column, the pump may be removed from the operating system for ease of maintenance or transfer to an alternate location.

Suction Vessel Mounted Pumps are used for product send-out, product transfer or the increase in pressure ("boosting") of cryogenic liquids within a system. This pump is typically installed into a pressure vessel called a suction vessel or "suction pot". By closing the suction and discharge valves, then applying an inert gas purge to the suction pot, the suction vessel mounted pump may be easily removed for maintenance or transfer to a similar location.

Compact Variable Speed Pumps are similar in design to Suction Vessel Mounted Pumps. This pump is primarily for use in co-generation facilities where greater flexibility is required during pump operation. By utilizing a Variable Frequency Drive (VFD) to regulate rotating speed, greater variation in discharge pressure for a given pumping capacity can be achieved. In addition to increased performance versatility, the use of a VFD will allow the compact variable speed pump to be started at a reduced frequency ("soft-start"), decreasing the starting current level and lowering the required ampacity of the electrical system.
