Trading and engineering company focusing on process pumps
In 2018, Copenhagen Pump was contacted by a service partner to replace 1 of 3 existing IMO Pumps. In connection with the tender, the Port of Aarhus raised a number of perceived challenges, which we later found during a site visit to be pressure surge related.
In consultation with the parties, it was decided to install an external bypass valve which immediately proved to solve problems with pressure surges at start-up and during shutdown. The IMO ACF pump has a built-in bypass valve/safety valve whose primary function is to protect the pump. The internal valve can function as a working valve, but this results in increased and unnecessary wear of wear parts in the pump. An ACF pump is also a rather large and heavy pump. It therefore makes sense to install an external bypass valve in situations like this where the pump is used to connect external piping systems, in this case tankers and ships where you cannot control the receiver's system operation.
The change from generation 2 to generation 5 was relatively painless, as the two generations are externally consistent with each other.
