IMO Pump Bulletin Describes Twin Screw Pumps

Geared Twin Screw (GTS) pumps, capable of moving large quantities of crude oil and almost any other liquid cargo or water ballast, are fully described in a bulletin published by the IMO Pump Division, DeLaval Turbine Inc.

GTS pumps have particular application in the marine field, as they can handle liquids with an extremely wide range of viscosity at discharge pressures up to 300 psig, and are available in deck mount, bulkhead mount, deep-well and other configurations. Applications include loading, off-loading, transfer, and as combination cargo and stripping pumps because of their high suction capability.

Within a given case size, the capacity of GTS pumps can be changed by installing a new set of screws. The bulletin includes operating data, capacity ranges and dimensional details.
