Ballast Pump · Pumps
Close-coupled centrifugal pumps, like those in the SPX FLOW CombiBloc Serie, operate by using a motor and pump impeller mounted on the same shaft, reducing coupling length and vibration. Available in various sizes from 32 mm to 150 mm diameter, these pumps handle flow rates ranging from 30 m³/h to an impressive 800 m³/h, suitable for fresh water, sea water, and process applications. With construction materials including cast iron and bronze, they are robust enough for demanding environments. Common issues include mechanical seal leakage, motor bearing wear, impeller blockage in dirty services, and cavitation damage. Regular maintenance, including seal replacement every 8000 hours and motor bearings according to the manufacturer's schedule, is essential for optimal performance.
