PUMP. Submersible Sewage Pumps Type DSC4 FEATURES/BENEFITS

Transcription

1 PUMP Submersible Sewage Pumps Type EBARA submersible pump type is constructed of rugged cast iron with heavy-duty motor suitable for municipal water and wastewater, sewage and flood control applications. FEATURES/BENEFITS Heavy-duty, air-filled Class H and Class F insulated motor - operates cooler with higher efficiency; enhances durability of operation. Watertight cable entry system - protects against moisture and capillary action; reduces maintenance cost. Float type leakage detector - provides early warning of mechanical seal failure; avoid costly motor repairs. Self-cooling jacket - high reliability, effectively dissipates heat; long operating life is expected Cartridge type, duplex mechanical seal - assembled in tandem arrangement; easy maintenance and high reliability. High efficiency closed type impellers - ability to pass larger solids with high outputs to prevent clogging;lowers operating cost. - ensure lower thrust load for longer bearing life.

6 Submersible Sewage Pump Submersible Sewage Pump WATER TIGHT CABLE ENTRY SYSTEM SECTIONAL VIEW PUMP The design of the cable entry is critical to prevent the ingress of water into the motor. Thus EBARA is adopting a unique water-tight cable entry system that ensure long-lasting and trouble-free pumping operation. How it works : Water cannot leak into the motor even if the cable is cut or damaged. Each cable lead is soldered then isolated by rubber sealing, thus preventing any capillary action. Thick molded shoulders bolted to motor cap provides exceptional strength and forms a strong compression seal. Increased diameter of cable with molded entry resists strain from bending.
