VIKING HEAVY DUTY MOTOR SPEED PUMP Section Page Viking 4076/4176 (standard pump) GPM Major Design Features Designed to run with 50Hz synchronous motor speeds while providing high capacity. Enlarged porting and loading groove provides improved suction performance and reduced NPSHr. Optimized gear geometry delivers high-speed performance with improved noise levels. Metric design includes DIN flanges, DIN seal chamber, IEC motor mount, metric fasteners and shaft extension. DIN seal chamber accepts a wide range of seal options. Rotor shaft is designed to resist deflection and wear seen at higher speeds. Circulation line from the port to the mechanical seal provides liquid to the seal faces to extend seal life. Bearing housing assembly allows for adjustment of running clearances to compensate for slip and wear, extending the service life of the pump. Also provides additional shaft support in high pressure applications, and provides a method of shaft support other than the motor bearing. Pressure Range Six sizes available each with three mounting options; flange mount, motor bracket mount or with a bolt on foot for a base mount. Flow Range Ductile iron externals for thermal shock applications is an affordable alternative to steel. LQE4176 WITH BOLT ON FOOT ①Values shown represent minimums or maximums. Some special LQE4076 WITH FOOT BRACKET AND IEC MOTOR construction or consideration may be required before a cataloged pump can be applied to an application involving maximum pressure or minimum or maximum temperature and/or viscosity. ②Nominal capacities based on handling thin liquids at low pressures.
