Embodiments of the present invention provide a non-electric pump. Gas pressure, typically steam or compressed air, is used to move a liquid, typically steam condensate, from a low pressure source to a high pressure destination. A tank fills with liquid from the source. Once full, the motive pressure is admitted to the tank and the pressure forces the liquid to the destination. When the tank is empty, the motive valve shuts and a vent valve opens to vent off the motive gas. A balanced trap plunger with an unattached float linkage provides for improved pump efficiency. |
