Higher Output Series G Metering Pump

A rugged design for the toughest challenge, now with NSF/ANSI 61 and 372 certifications.

Available in two motor driven models – the SD and the SG – the Series G Metering Pumps feature rugged aluminum construction specifically engineered to handle higher output applications in harsh environments. Certified with NSF / ANSI 61 and 372 for municipal compliance and safety assurance, the Series G is the right choice when choosing a pump for water treatment applications, like coagulation and flocculation.

By combining a heavy-duty industrial drive with state-of-the-art design, the Series G offers a mechanically actuated diaphragm that provides smooth output with reduced potential for system shock and hydraulic oil contamination.

External speed control, stainless steel fasteners and NSF certifications make this powerhouse pump perfect for water treatment applications.

 

 

Benefits:

  • Compared to solenoid pumps or lost motion designs, the Series G pumps offer a robust, metallic worm gear drive along with an industrial duty variable eccentric stroke adjustment mechanism to yield a 10 to 1 turn down ration with smooth velocity profiles
  • This pump is designed to last. The PTFE, high performance diaphragm design eliminates the stresses inherent in most designs – plus, all gear components operate in an oil bath for long life.
  • Available in three frame sizes, the Series G pumps are able to accommodate a wide selection of liquid ends
  • Manual controls allow for precise stroke length adjustment

 

Standard Features

  • High flow rates up to 312 GPH (1180 Liters/hr.)
  • Mechanically actuated diaphragm liquid end eliminates flow restrictions
  • Durable, metallic housing designed to withstand tough environments
  • High efficiency motors minimize heat buildup
  • Reliable low flow performance is a result of high-performance check valves with machined seats
  • Precision stroke adjustment can be operated while the pump is running or stopped
  • Steady state accuracy – ± 1% of full capacity over the 10 to 1 turndown ratio
  • Liquid Temperature Range – 14° to 122° F (-14° to 50° C)
  • Coating includes a 2-part epoxy
  • UL, CUL, ETL certified
  • Now NSF / ANSI 61 and 372 certified for municipal compliance and safety assurance

 

Optional Features

  • Safety valves
  • Back pressures valves
  • Pulsation dampeners
  • Degassing valve
  • Repair & preventive maintenance kits
  • Calibration columns
