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 l/h. The large illuminated LC 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.

Advantages

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

Applications

Highly automated processes in nearly all industries
Cooling water circulations: dosing of biocides, corrosion inhibitors, defoamers and other additives
Chemical industry, e.g. in mini-plants

Features

Capacity range 0.74 - 32 l/h, 16 - 2 bar
Continuous stroke length adjustment from 0 - 100%
Digitally accurate stroking rate via keypad and large LC display
Feed rate display in strokes/min. or l/h
Programmable pressure levels
3-LED-Display for on/off, warning, and error
Liquid end materials: PP, Acrylic/PVC, PVDF, PTFE, stainless steel
Patented coarse/fine bleeding on PP, Acrylic/PVC and PVDF
Self-bleeding liquid end version in PP and Acrylic/PVC
HV liquid end for highly viscous media
Dosing monitor input, adjustable error stroke counter
External control via voltage free contact with optional increase/decrease pulse function
Optional external control via standard signal 0/4 - 20 mA
Two level float switch connector
Optional 14 day process timer
Protection class IP65
Low Voltage 12-24 V DC, 24 V AC/DC Option
Optional concentration entry for proportional flow dosing
Option 4-20 mA output corresponds to the product of stroke length and stroke frequency
Power relay, especially in combination with the process timer for switching higher powers (230 V-8 A)
Audible alarm for pre-alarm/fault corresponds to intermittent/continuous tone
Interface for PROFIBUS®-DP

Material Options for Liquid Ends

Polypropylene: The low-cost alternative, resistant to many acids and alkaline solutions. This material is typically used in water treatment applications.
Acrylic Glass: Offers outstanding resistance to chlorine bleaching solutions and is a transparent liquid end material. This offers the advantage to observe the pumping process in the liquid end. Air inclusions or crystalline deposits that may interrupt the metering process can be detected and removed.
PVDF: Resistant to concentrated or oxidizing acids and alkaline solutions. A less expensive alternative to PTFE.
PTFE: Best suited to meter highly concentrated or oxidizing acids and alkaline solutions
Stainless Steel: For metering solvents and liquids containing oil

For gas-emitting media self-bleeding liquid end versions are available in polypropylene and acrylic glass.
