A method and apparatus is provided for supplying both cryogenic liquid and vapor from a storage tank to a pump to reduce the need for venting. The pump is operable to pump cryogenic liquid or a mixture of liquid and vapor. Different operating modes are selectable to control mass flow rate through the pump. With one operating mode a high flow rate is achieved by supplying only cryogenic liquid to the pump. By selecting another operating mode, a lower mass flow rate is achieved by simultaneously supplying liquid and vapor from the storage tank to the pump. The pump preferably has an inducer with at least two chambers and valves for recycling excess fluid within the inducer instead of returning it to the storage tank. The reciprocating pump is preferably double acting such that fluid is discharged from the pump during both extension and retraction strokes.

The method of claim 13, further comprising the steps of inserting a spindle into each of said take-up spool and said supply spool. 15. The method of claim 14, further comprising the step of inserting said spindles in said openings of said sideplates. 16. The method of claim 14, wherein the spindle inserting steps occur before the spool inserting steps. 17. The method of claim 13, wherein the first and second ends of the take-up spool inserting steps are performed one after the other.
