TECHAP’s
metering pumps are rotate-lift-rotation piston pumps with electronically
regulated drives. The pistons and cylinders are made of ceramic, a
material with excellent chemical and mechanical properties that are
resistant to practically all liquids and gases (chemicals, solvents,
oil and alcohol). The basis of the new metering system is the internationally
patented TWIN-BALL SYSTEM that makes it possible to generate the lift-rotate
movement of the piston. With conventional lift-metering pumps, the
input/output valves are always necessary and difficult. Now, with
the rotating function, they are superfluous. The lift movement that
is simultaneously dependant upon the rotating movement generates suction
and displacement. All of the parts coming into contact with the liquid
are inert and the metering system is not sensitive to soiling. Flakes
and solid matter in the metering substance are non-damaging to a limited
extent. This system is also self-suctioning up to 30 mbar absolute.
Further benefits: reproducible metering accuracy suitable for liquids
of high viscosity, temperatures up to 180° C, pump head may be heated
in a special design (optional equipment). In addition, the metering
system also works backwards by reversing the drive direction (optional
equipment).
The metering error of pumps excluding control
errors < 0.2%. Pressure fluctuations do not impair the metering quantities
of the pump (only depends upon the metering material and control mechanism).
This metering system may also be used as a volumetric measurement
with inlet under pressure and modified as a vacuum pump up to 97%
vacuum (refer to vacuum pump). Other systems with greater performance
up to 100 mbar are presently in long-term testing. We also have pulsation-free
double-piston pumps with the KTD model designation available. This
makes completely new applications possible.
NOTE: Higher-viscosity substances lower pumping capacity noticeably
because of the suction behaviour of the substances to be conveyed
(exhalation, compressibility, flow behaviour, drive performance, etc.)

We
are offering five drive applications at the present:
KTF = fixed-speed drive for constant metering
KTH = speed regulation with a potentiometer.
KTZ = pump unit with converter and no drive motor.
KTC = µ-controlled as described below:
KTD = pulsation-free double-piston metering pump with C
The high-quality direct-current drive with gear stage is driven by
TECHAP’s C2 control mechanism. The metering pump is constantly monitored
by the built-on increment transmitter and it regulates the target
value. The two-line display with 5 user-led buttons makes programming
easy.
