Powerful, built to last with a plunger
The plunger metering pump Makro TZ (TZKa) has an adjustable eccentric drive mechanism and, together with the Makro TZ diaphragm metering pump, forms a range of drive mechanisms with stroke lengths of 10 and/or 20 mm. This covers the capacity range from 8 to 2,100 l/h at 320 – 4 bar. A wide range of drive versions is available, including some for use in Exe and Exde areas with ATEX certification.

Electrical connection 230 V (±10 %), 50/60 Hz, 40 W mech. stroke length display fitted on the Makro TZ power end.
Special voltage/higher degrees of protection/explosion protection upon request.
Makro TZ control drive
Control drive consisting of an actuator with servomotor and integral microprocessor controller for stroke length adjustment via a standard signal. Technical data see actuator.
Design:
Standard signal current input 0/4-20 mA corresponds to stroke length 0 -100 %, manual /automatic operation switch, key switch for stroke adjustment in manual mode. Actual value output 0/4-20 mA for remote display.
Variable speed motors with integrated frequency converter (identity code specification V)
The following functions are integrated in the terminal box cover:
- Start/Stop switch
- Manual/external operation switch (0/4 - 20 mA)
- Potentiometer for speed control in manual mode
- Onn request externally controllable via PROFIBUS® DP
Speed controllers with frequency converter (identity code specification Z)
The speed controller (complete) comprises a frequency converter and a variable speed motor (see also identity code specification R). The frequency converter is accommodated in an IP 55 rated protective housing with integral control unit and main switch.
Externally controllable with 0/4 - 20 mA or 0 - 10 V corresponding to 0 - 50 (60) Hz output frequency.

Motor data sheets can be requested for more information. Motors for Sigma basic pumps, special motors or special motor flanges are available on request.
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.
