gamma/ L Diaphragm Metering Pump


The gamma/ L is the world's first calibrateable pump of its performance class. The metered quantity is directly displayed in gph. The large illuminated LCD display makes sure that all displayed variables are simple to read. The integrated 2-week Process-Timer (optional) offers an extremely wide range of application possibilities

Benefits

  • No metering errors: direct clear text settings and feed rate monitoring.
  • Cost and space-savings thanks to integrated 2-week process timer. The intelligent alternative to the time switch.
  • Easy-to-read values thanks to the large backlit LC display – even in tricky viewing conditions.
  • Problem-free connection to interface complex process feed systems with optional PROFIBUS®-DP
    interface.
  • Level monitoring of the chemicals via an input for a two-stage float-type level switch with early warning function

Features

  • Microprocessor based technology for flexible control: Manual stroke length and frequency, Batch, Remote on/off, Contact Pulse, Analog
  • Certified to NSF/ANSI 61 (acrylic or PVDF liquid ends)

(Note: Above capacities and suction lift refer to pumps tested on water at 115 VAC, 60 Hz, and an ambient temperature of 70*F (20*C). Higher specific gravity fluids will reduce suction lift. Capacities will be slightly reduced from published ratings if pumps are skid mounted.)
Higher viscosity fluids will reduce capacity. Liquid ends for highly viscous media have 10-20% less metering capacity and are not self-priming.
Standard connectors are 1/2" MNPT or 5/8" hose barb. Positive suction is recommended.
* Not available with bleed valve.
** SS versions use 1/4" female threads except models 0220, 0420, and 0232 which use 3/8" female threads.
*** Only available in SS and Acrylic liquid ends.
Universal control cable necessary for external Beta control.

What are the primary advantages of a solenoid driven metering pump?

The pump drive has only one moving part, the armature shaft. Generally, the less moving parts, the more reliable the pump. Solenoid pumps are very good for low pressure applications and compensation for line voltage fluctuations are excellent.

When discharging to atmosphere, what steps will improve repeatability of dosing?

Installing a spring in the discharge valve of the pump gives some improvement, but for the maximum improvement, a backpressure valve should be installed at the end of the line.

How do you use a flow monitor with a Gamma/L pump?

Connect the flow monitor to the right top connector on the front of the gamma/L pump. The flow menu will only appear when the flow monitor is connected. Push the "P" for 3 seconds. Use the up and down arrow keys to get to the "SET" menu. Press the "P" key momentarily to accept the menu. Use the up and down arrow keys to get to the "FLOW" menu. Press the "P" key momentarily to accept the menu. Use the up and down arrow keys to turn "ON". Press the "P" key momentarily to accept the menu. Use the up and down arrow keys to set the number of strokes the pump will stroke before it stops due to flow. Press the "P" key momentarily to accept the number.

How do you set the mA function on the Gamma/L pump?

Set the pump in the analog mode. Push the "P" for 3 seconds. Use the up and down arrow keys to get to the "SET" menu. Press the "P" key momentarily to accept the menu. Use the up and down arrow keys to get to the "ANALG" menu. Press the "P" key momentarily to accept the menu. Use the up and down arrow keys to select curve, 0-20 mA or 4-20 mA". Press the "P" key momentarily to accept the menu. If you choose the curve setting you will have additional settings please see section 7.4.2 of the operating manual. SEE WORD DOC FOR EXTRA!

How do you set the Access Code on the gamma/L pump?

SEE WORD DOC

How do you calibrate the gamma/L pump?

Before calibrating, make sure the pump is plugged into the appropriate electrical outlet and the suction and discharge lines are connected to the pump. Set the stroke length, stroke frequency, and pressure to the desired settings, set the pump to "MANUAL" mode, and prime the pump. SEE WORD DOC FOR EXTRA!
