Description HS & HSZ are single-phase pump units with the durability equivalent to three-phase drainage pumps since the wear parts are made of abrasion-resistant materials. The side discharge, spiral design allows smoother passage of the sucked solid matters. The shaft-mounted agitator prevents “Air Lock” that tends to take place on vortex or semi-vortex pumps. Features Automatic start/stop operation controlled by flow switch. Built in sintered alloy agitator to prevent air lock and stir slurry. Anti wicking cable offers maximum protection against water penetrating through the cable entry should the cable be damaged extending the life of your pump. Vortex impeller designed for “high gap structure” made of urethane rubber that permits solid handling to 7 mm. Thermal motor protector Semi-vortex impeller designed for “high gap structure” made of urethane rubber that permits solid handling to 7 mm. Dual mechanical seals with silcon carbide face provides 5 times higher corrosion wear and heat resistance than tungsten carbide. Performs like the non-automatic version in every aspect of construction site usage requiring a tough and durable pump. No control panel or float switches are required. Performs like the non-automatic pump with no special float installation required. Requires very small space to operate – only 8 3/4″ diameter. Urethane, Semi Vortex Impeller and Wear Plates for maximum durability while maintaining pump performance. Oil Lifter provides lubrication of the seal faces. (Patented) V-Ring Seal Protector designs mechanical seals from abrasive particles. Environmentally friendly, reducing electrical costs and operational noise. (Technical Features of EL Relay Unit (Level Sensor) Sensitive electrodes detect water to start pump operation even when foreign materials are present. Internal timer eliminates frequent on/off operation in rough water to extend motor life. Relay sensor is completely moulded in resin and covered by a rubber case for protection against rough handling. Job site tested for more than 30,000 on-off cycles without failure or damage.
