CombiNorm

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.
