Shipboard engineers rely on dependable pumps for a variety of critical tasks, from maintaining freshwater systems to circulating seawater for cooling. Johnson Pump offers the CombiNorm, a marine-rated centrifugal pump designed for both freshwater and seawater applications. This electric, end-suction pump is built specifically for marine service. Common issues encountered with the CombiNorm include mechanical seal leakage, bearing wear due to misalignment, impeller cavitation damage, and casing corrosion in seawater environments. To ensure optimal performance and longevity, regular maintenance is essential. This includes checking coupling alignment, vibration, and leakage. During overhauls, it's crucial to inspect the wear rings, shaft sleeve, and bearings. Standard spare parts readily available include the mechanical seal, bearing kit, shaft sleeve, wear rings, and casing gasket.

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.
