Note: If a seperate drop line is installed, we recommend to load through the drop line only.
lf this is not possible due to valve arrangement, use following procedures to avoid pressure peaks in the cargo piping during loading.
1.1 Procedure for loading through the drop line and cargo pump
1. 1.2 Keep manifold valve closed until the cargo reach the manifold.
1. 1.3 Open the manifold valve partly to fi ll cargo line on deck.
1.1.4 ** Open the cargo pump discharge valve and drop line valve slowly, until you reach maximum capacity, or maximum 8 bar cargo pressure, measured at the top of the pump. For minimum opening time, see table on page 4. The standard Framo cargo pump design meets all applicable rules for stripping under the IMO Annex II requirements. However, as an option, the Framo cargo pump can be equipped with a vacuum drain line that will empty suction well completely and allow for a dry tank top and quick re-loading of cargo.

The hydraulic section is surrounded by a cofferdam that completely segregates the hydraulic oil from the cargo.

The old versions of Framo pumps were of two types with respect to the loading of the cargo.
Loading through the Framo pumps without anti-rotating units was not allowed.
This is because as we load the cargo through it, the impeller of the pump would rotate in opposite direction which could damage the pump seals, impeller or even hydraulic motor because of additional back pressure created by pump rotating in the opposite direction.
With the anti-rotating unit fitted in the Framo pump, we could load the cargo through the pump as the anti-rotating unit would not allow the impeller to rotate in opposite direction.
But this system was a long time back. The Framo pumps have seen many technological changes since then.
The modern Framo pumps rotate only in one direction. So even if we load through the pump, it is fine. But there are some rules for this.
Rule #1: If a drop line is installed it is highly recommended to use the drop line and avoid loading through the pump.
Rule # 2: For loading through the pump, follow the instructions provided in the Framo manual.
Rule # 3 One hundred years of solitude book pdf download. : Never exceed the cargo pressure to more than 8 bar measured at the top of the pump (pump stack).
Once these rules are followed, it should be safe to load through the pump (through discharge line).
