MINIDOS A
General description
The MINIDOS A series is the result of a consistent,
ongoing development of proven technology and the use
of modern plastics.
With metering rates of 3 l/h up to 39 l/h the MINIDOS
leak-proof diaphragm metering pump has a wide range
of application.
The MINIDOS A is available as single metering pump with
the metering head mounted on the right-hand side.
Metering head
Standard materials for the metering heads are rigid
PVC, PVDF and stainless steel. Other materials are available
upon request.
Valves
Priming and discharge valves are designed as double-ball
valves. For metering chemicals with a viscosity higher
than approx. 400 mPas spring-loaded single-ball valves
are recommended.
Separation chamber
The diaphragm flange between metering head and gearbox
is designed as separation chamber. In the case of diaphragm
rupture resulting from wear the leakage is directed
downwards by means of a
drainage pipe.
Drive
A three-phase sectional motor provides the electrical
drive. AC operation is also possible. In the case of
this sectional motor the conventional motor end plates
are replaced by the pump base and the gearbox. This
gives the MINIDOS A a compact form.
For metering pumps with variable-speed DC (ATG) or explosion-proof
motors, see MB 1 04 05. The gearing consists of a single-stage
worm gear and the gearing components as well as the
bearing
are lifetime lubricated. The discharge stroke is carried
out by an eccentric actuating the diaphragm by means
of a spring-loaded tappet. The suction stroke is effected
by spring return. Stroke adjustment can be carried out
either manually or electrically (ATE).
