Fuel oil/lube oil/viscous liquidsMedium

An internal gear pump designed for marine applications, the Viking Pump 4124A is a robust solution for transferring fuel oil, lube oil, and other viscous liquids. This electric-driven pump is specifically engineered for transfer service, ensuring reliable performance in demanding maritime environments. The pump’s capacity is marine-rated, as per the manufacturer's data sheet, making it suitable for applications where efficiency and durability are paramount. Common failures to be aware of include seal leakage, idler bushing wear, gear wear from solids, and relief valve malfunction. To mitigate these issues, it is essential to keep a stock of critical spare parts such as the mechanical seal, idler bushing, gear/idler set, gaskets, and relief valve components. Regular maintenance is crucial for the longevity and performance of the 4124A. During service and overhaul, it is recommended to check the discharge pressure and leakage, inspect the gear/idler clearances, and ensure the proper functioning of the relief valve. By adhering to these maintenance practices, operators can maximize the pump’s operational efficiency and minimize downtime.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
