The ProMinent MAKRO-TZ is an oscillating, pulse-free adjustable displacement pump. It is
driven by a standard three phase motor whose drive rotation is reduced by a worm gear (1),
transmitted to the push rod (4) via an adjustable eccentric cam (2) and a connector rod (3) and
thus converted into an oscillating movement. This drive principle guarantees precise control
positive execution of forward and reverse strokes, which is of particular benefit in overcoming
high suction lifts or when metering highly viscous media.
The stroke length is set by finely adjusting the eccentricity of the shift ring (TZ)(5), which
produces the oscillating stroke action. This drive principle guarantees a harmonious, purely
sinus-form stroke action at any stroke length. The smooth-running power end emits a minimum
of running noise.
The MAKRO-TZ power end series is available in two versions. The TZ Mb version has a
maximum stroke length of (TZMa: 6/9 mm) and is designed for operation with mechanically
actuated diaphragm liquid ends. The TZKa version has a maximum stroke length of 20 mm and is
designed for operation with piston or piston-diaphragm liquid ends. Both versions are also
available as power ends for double head metering pumps (TZMaD, TZMbD, TZHaD and/or
TZKaD).
