Kind Code:
A
Abstract:
To provide a reciprocating pump assembly.
The present invention teaches providing heating elements into the nose of an intermediate distance piece of a cryogenic reciprocating pump in order to warm the piston packing seals of the pump. The heating elements increase the temperature of the piston packing seals to limit deformation of the seals while the pump is in operation. In addition, a high temperature and dry vapor purge may be provided to the interior of the intermediate distance piece to reduce or eliminate rime from interfering with the piston packing seals.
