CombiBloc

A close-coupled centrifugal pump designed for marine and industrial service, Johnson Pump’s CombiBloc is a robust solution for handling fresh water, sea water, and process water. This electric drive pump is specifically engineered to meet the rigorous demands of maritime applications, ensuring reliable performance in various conditions. The CombiBloc features a compact design that facilitates easy installation and maintenance, making it an ideal choice for both marine and industrial environments. Common issues with the CombiBloc include mechanical seal leakage, motor bearing wear, impeller corrosion or erosion, and reduced capacity due to wear ring wear. To mitigate these potential failures, regular monitoring of the motor current, pressure, and seal leakage is essential. During preventive maintenance schedules (PMS), it is crucial to inspect the condition of the mechanical seal and bearings. For optimal performance and longevity, Johnson Pump recommends keeping a stock of typical spare parts such as the mechanical seal, motor bearings, impeller, wear ring, and gasket kit. These components are critical for maintaining the pump's efficiency and preventing unexpected downtime. By adhering to these maintenance guidelines, operators can ensure that the CombiBloc continues to deliver reliable service in marine and industrial settings.
