Features MAXIMUM OPERATING CONDITIONS TEMPERATURE (For Standard Buna-N Seal) INLET PRESSURE CASING WORKING PRESSURE 225ºF (07ºC) 00 PSI (689kPa) 250 PSI (723kPa) BURKS exclusive, unique regenerative type turbine pumps are designed to handle clear water and many other non-abrasive, lower viscosity liquids on high pressure, low capacity applications with the greatest possible effi ciency. BURKS is the only turbine pump with Life-Lok External Impeller Adjustment feature that allows readjustment of impeller without disturbing piping, disassembling pump or replacing parts. Gives up to 40% longer service life than turbine pumps of other designs.coupling guard furnished on all complete Base- Mounted units manufactured by Burks Pumps. Not furnished with purchase of pump only, but required. FOR TEMPERATURES TO 500 F (260 C) Series ES Pumps are available in a Jacketed Seal Cavity design for pumping hot oil, hot water and heat transfer fl uids in common use in high temperature heating or cooling applications. This feature greatly extends seal life in high temperature applications. To order, add suffi x J to pump catalog number for temperatures below 400 F (204 C) and add suffi x JK to pump catalog number for temperatures over 400 F (204 C). Example: ES6MJ. See Section on High Temperature Pumps for more information. QUALITY FEATURES: Self-Priming Compact, space-saving size Dependable carbon/ceramic mechanical shaft seal for temperatures to 225 F (07 C).
