4197 Series Motor Speed Product Line Stainless Steel Internal Gear Pumps
Viking’s Motor Speed Product Line 4197 Series internal gear pumps are available in capacities up to 75 GPM.
These pumps can be furnished directly connected to a 50 Hz or 60 Hz motor. 4197 Series™ and 4197-SEP Series™ pumps are designed for foot type horizontal mounting. These pumps are built for continuous or intermittent duty for such applications as filtering, circulating, transferring or booster service in general industrial, petrochemical, and other industries.
The 4197-SEP Series™ pumps are specially fit with low temperature materials suitable for subzero solvent transfer or circulation applications. They are also assembled and tested using only food grade liquids. Both pump series are furnished as standard with mechanical seal construction to minimize liquid loss and for shaft protection. The thrust control provides micrometer adjustments for accurate rotor and shaft positioning to help you keep operating with new-pump efficiency through years of heavy duty service.
Viking Pump 4197 Series Features & Benefits
• Ball Bearings Standard.
» Pumps are equipped with inner cas ing ball bearing installed outside of mechanical seal and a radial thrust ball bearing permitting heavy-duty service up to 200 PSI (14 BAR). Bearings are “Sealed for Life”.
• Integral Over-Pressure Relief Valve Standard
» Permits bypassing of liquid from discharge to suction side of pump. Prevents build up of pressure in dis charge line. GG, HJ and HL size valve mounts on pump head. AS, AK and AL size valve mounts on pump casing.
• Mechanical Seal Standard
» All 4197 Series™ and 4197-SEP Series™ pumps are furnished with a positive drive mechanical seal. The seal is a simple, self-adjusting, non-leak method of shaft sealing. It is especially suited for handling liquids such as alcohols, solvents, etc.
• Stainless Steel Pumping Elements Standard
» Internal pumping gears are constructed of Type 316 and Type 770 Stainless Steel Alloy. This allows high speed, non-galling operation, handling all types of liquids up to 25,000 SSU (5,500 cSt). PPS composite idlers are also available for thin liquid applications.
