Ballast Pump · Pumps
Side-channel self-priming centrifugal pumps are a versatile category of maritime equipment, ideal for handling a variety of liquids including sea water, condensate, and ballast. The Flowserve (SIHI) LPH Series exemplifies this class, offering a reliable solution for pumping applications with a broad capacity range of 30 to 800 m³/h. The pump series, introduced in 1980, is designed with side-channel technology that ensures self-priming capability, making it suitable for various industrial and marine environments. Available in DN sizes from 40 to 150 mm, the LPH Series can handle a wide range of flow and head requirements, with flow rates up to 800 m³/h and heads up to 150 meters. The pump series includes approximately 80 variants, catering to diverse operational needs with electric drives. However, common issues such as mechanical seal failure, stage wear, bearing wear, and self-priming failure due to air leakage from the suction side can occur. To ensure optimal performance, regular maintenance is essential, with mechanical seals needing replacement after 8000 hours of operation and bearings after 20,000 hours. Spare parts for the LPH Series are available through Flowserve SIHI's global service network, ensuring easy access to necessary components.
