6.2 Pumping considerations

6.2 Pumping considerations Since the rate of separation depends on the oil globule size it will be appreciated that any disintegration of oil globules in the oily feed to the separator should be avoided and this factor can be seriously affected by the type and rating of the pump used. Tests were carried out by a British government research establishment some years ago on the suitability of various pumps for separator feed duties(Double vane, Triple screw and Single vane

6.2 Pumping considerations It follows that equal care must be taken to avoid turbulence occurring in pipework eeain the separator Placing a filter on the discharge side of a separator will 'polish the discharge but overloading must be avoided

6.2 Pumping considerations • It follows that equal care must be taken to avoid turbulence occurring in pipework feeding the separator. • Placing a filter on the discharge side of a separator will 'polish' the discharge but overloading must be avoided
