Meta plunger 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 Piston Metering Pumps
Speed controllers in metal housing (Identity code characteristic Z)
Frequency changer built into IP 54 protective housing and main switch designed for max. 0.37 kW motor output.
Externally controlled with 0/4-20 mA / 0-10 V to correspond to 0-50 (60) Hz output frequency.
Integrated controller with versatile functions e.g. switching between external/internal control. With internal control, frequency input is via arrow keys. Multi lingual fault message display and motor temperature monitoring (thermistor-protection).
The speed controller assembly consists of a speed controller and a variable speed motor (see also identity code characteristic R).

The motors are designed in compliance with the Ecodesign 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/EU in premises at risk from explosion. Ensure that the explosion group, category and degree of protection specified on the label corresponds to or is better than the conditions prevalent in the intended field of application.
