Meta plunger metering pump – durable and high-performance
The Meta (MTKa) is a plunger metering pump, the pump capacity of which can be precisely adjusted in 0.2% increments, either manually or optionally with an electric actuator An actuator is used to move the adjustment spindle for the stroke length adjustment of a ... more in the glossary or control drive. A wide range of power end versions is available for use in areas at risk from explosion with ATEX certification.

Control of Meta Plunger Metering Pumps
Speed controllers in metal housing (identity code specification Z)
The frequency converter is accommodated in an IP 54 rated protective housing with integral control unit and main switch, suitable for max. 0.37 kW motor capacity.
Externally controllable with 0/4-20 mA or 0-10 V corresponding to 0-50 (60) Hz output frequency.
Integrated control unit with versatile functions, such as switching between external/internal control; frequency specified using arrow keys with internal control, multilingual fault message display etc. and motor temperature monitoring (thermistor protection).
The speed controller assembly comprises a frequency converter and a variable speed motor (see also identity code specification R).

The motor power is dependent on the pump type (see technical data).
Motor data sheets can be requested for more information.
Special motors or special motor flanges are available on request.
The motors are designed in accordance with the Eco Design Directive 2009/125/EC.
Information for use in areas at risk from explosion
Only use pumps with the appropriate labelling in line with the ATEX Directive 2014/34/EC in premises at risk from explosion. Ensure that the explosion group, category and degree of protection specified on the label correspond to or are superior to the conditions prevalent in the intended application.
