Inlet Gas Or Vapor; Service Liquid - BeaconMedaes Lifeline Camel Installation, Operation And Maintenance Manual

"Camel" Liquid Ring Medical Vacuum
A.3.2

Inlet gas or vapor

The inlet gases or the vapor/gas mixture should not contain solid particles. However, the pump can handle small
quantities of liquids or powders. If the temperature of the inlet gas or vapor is higher then160°F, the service liquid
flow rate should be increased by up to 50% over the flows specified in Table A-2.
A.3.3 Service Liquid
While the pump is operating, it must continuously be fed with clean service liquid. Solid particles in the service
liquid, such as sand or mud will reduce the life of the pump. If solids are present in the service liquid, it is
recommended that a strainer be added to the seal piping plan. Service liquid temperature should be maintained at all
times to assure proper operation. Higher than recommended service liquid temperatures will result in reduced pump
capacity. In certain high inlet temperature cases, it is recommended to use a pre-condenser in order to improve
pump cooling.
