9. TECHNICAL DESCRIPTION AND DIAGRAMS

Mechanical Layout

The ARDO suction pumps MASTER/SENATOR work according to the principle of a piston/
cylinder system.
Both power units are based on a modular driving concept, equipped with 2 cylinder units.

MASTER 45 2 cylinder power unit (approximately 300 rpm)
SENATOR 30 2 cylinder power unit (approximately 220 rpm)

A two-stage belt transmission was developed for driving the cylinder units that may be
used for both power units (MASTER and SENATOR).

Transmission reduction for the two power units can be adjusted with the two belt pulleys
of the first reduction level (motor pinion + belt wheel = 1. level).

For both power units a bipolar capacitor motor with built-in temperature sensor is used.
This protects the motor coil from heating to more than 125°C.

The piston is driven over a linear unit (slide). By using this system, the piston system is
exposed to only minimal thrust forces, which ensures low wear and high service life.
In MASTER/SENATOR the pistons work in angles of 90° to each other. This ensures a
well-balanced run of the pump with low vibration levels.
