gamma/ XL

diaphragm metering pump

Energy efficient and NSF approved

 

The new gamma/ XL is a solenoid metering pump with predictive intelligence. Thanks to its controlled solenoid drive with sensor-free pressure measurement, it detects hydraulic faults even in the case of minimal deviations – immediately and optimally matching its output to the pressure conditions and properties of the medium while protecting the pump and piping systems from overload situations. The gamma/ XL covers a capacity range of .08 GPD at 362 PSIG to 20.74 GPH at 29 PSIG (depending on pump version).

 

Features & Benefits

 

• Electronic stroke length adjustment via click wheel

• Volume adjustment in GPH or LPH

• Manual, Analog, Contact and Batch modes optional

• Integrated system pressure measurement

• BUS interfaces such as Profibus, CANbus, PROFINET and Modbus

• High visibility of LED-indicator lights

• Large illuminated display

• Analog output for stroke length and stroke rate transmission

• Auto compensates programmed feed rates during back pressure fluctuations

• As low as 1 mL/hr continuous feed rate with regulated solenoid drive

• Turn down ratio up to 40,000:1

• Integrated pressure measurement and display

• Available diaphragm rupture indicator

• Integrated 7-day timer

• Detects Overpressure/ No Pressure (broken discharge line) and gas in the liquid end

• Automatically sets optimal speed and stroke based on GPH settings (when set to automatic)

• New configurable input/output

• gamma/ XL and delta® footprints are identical

• NSF/ANSI 61 Approved Liquid Ends
