It is suitable for water containing sand and small particulate matter. This cast iron pump operates reliably under continuous site running.\u003c\/p\u003e\n\u003cp\u003eThis model features a hydraulic performance characterized by a maximum head of approximately 11.0 m and a maximum flow volume of approximately 2,080 L\/Min. Powered by a three-phase, approximately 3.7 kW induction motor, the pump incorporates an approximately 100 mm discharge outlet for bulk liquid transfer.\u003c\/p\u003e\n\u003cp\u003eThe KRS43.7 features the pump features a ductile cast iron semi-open impeller designed to resist abrasive wear from suspended sand and aggregate. This semi-open design maintains its operational balance and dewatering performance over long running periods. It supports the smooth passage of minor sand and sediment deposits.\u003c\/p\u003e\n\u003cp\u003eThe mechanical construction comprises a heavy gray cast iron casing and motor frame. A dry-type induction motor includes an automatic circle thermal protector that reacts to overcurrent or high motor heat. Double silicon carbide mechanical seals are located in an isolated oil chamber containing a turbine oil lubricant and the Tsurumi-patented Oil Lifter. Capillary water ingress is prevented by an anti-wicking cable entry block.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFeatures a heavy gray cast iron casing and motor frame provide high durability for site dewatering.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIncorporates a ductile cast iron semi-open impeller offers wear resistance against abrasive sand.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eUtilizes a low-speed 4-pole motor running at 1500 rpm reduces wear and extends service life.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDesigned with a top discharge, side flow layout maintains cooling when operating exposed to air.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEquipped with a dual inside mechanical seals with silicon carbide faces housed in turbine oil.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIncludes a anti-wicking cable connection block stops capillary moisture ingress into motor windings.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eUses a patented Oil Lifter delivers continuous lubrication and cooling down to one-third oil level.
