Abstract

La presente invención enseña proporcionar elementos de calentamiento en la punta de una pieza de separación intermedia de una bomba de pistón criogénica para calentar las juntas de pistón de la bomba. Los elementos de calentamiento incrementan la temperatura de las juntas de pistón para limitar la deformación de las juntas mientras la bomba se encuentra en operación. Además, una purga de vapor seco caliente puede proporcionarse al interior de la pieza de separación intermedia para reducir o eliminar la escarcha para que no interfiera con las juntas de pistón.
