5 Optional modules
5.1
Gear box module (optional)
The gear box module enables to operate the pump at very low speeds and
increases the torque of the motor for the delivery of highly viscous liquids or for
application with increased operating pressure. The gear box module is available
with the following reductions: 4.4 : 1, 19 : 1 and 84 : 1 in combination with
the pump heads mzr-2542 and mzr-2942. The length of a micro annular gear
pump with the gear box module increases by 16 mm to 19 mm (see table 8).
For pumps with the gear box module the position of the slip fittings to the
connection cable is undetermined.
