Pump unit GMA

Description:
Actuation:
Pump:
Operating instructions:
The pump unit GMA is actuated by a three-
phase A.C. motor or a D.C. motor (C), which
is flanged to the pump casing (A) from the
bottom.
At the radial piston pump there are up to
three pump elements (B) arranged radially
around an eccentric (F), which is
surrounded by a rolling bearing. On rotation
of the actuator or the eccentric shaft (E)
respectively the pump piston (G) of each
pump element designs a suction or a
delivery stroke per revolution and thus
delivers the lubricant out of the reservoir (D)
to the lubricating points. The delivery
volume can be adjusted at each pump
element individually. Depending on the
operation (lubricant, lubricant supply etc.)
the pump unit can be equipped with
different pump elements, reservoir and
monitoring units.
For the lubrication pumps only clean oil or
grease from original containers may be
used. If, before putting into operation, the
lubricant is not filled through the filling
nipple, the pump must be filled up to the
vane with gear oil during initial filling to
ensure good venting. The lubricant lines
must be clean and free from obstructions.
Do not connect them to the lubrication
points before the lubricant emerging from
the lines is free from air bubbles. Check all
connections of the pressure lines for
leakages.
Lubricant: The intended lubricant must be
suitable for use with centralized lubrication
equipment.

Operation of pump elements:
The suction stroke (fig. 1) is accomplished
by the delivery piston (1) and the control
piston (2). During that operation the delivery
piston (1) is actuated by the eccentric shaft,
and the control piston (2) by the spring. The
control piston closes the pressure hole (3)
and, depending on the set delivery capacity,
remains at a certain position. With the
delivery piston moving on, a vacuum will
build up within the dosage area. After
opening the suction hole (4) by the delivery
piston, the lubricant starts to be sucked off
the reservoir.
In case of pressure stroke (fig. 2) the
delivery piston (1) moves to the left. As a
result, the suction hole (4) will be closed
with the lubricant available between the
delivery and control pistons (2) being
shifted until it clears the pressure hole (3)
and the lubricant is delivered through the
delivery piston up to the outlet. The pumps
are supplied with their delivery capacities
being set at maximum, i.e. at full stroke
setting.
Delivery volume adjustment:
The can be adjusted
continuously between 25 and 100% of the
nominal delivery volume. After having
removed lock screw , the stroke is to be
changed by means of the enclosed spanner
through adjustment nipple . When turning
the nippe to the right, delivery volume will
decrease. At the adjustment nipple, there is
a hexagon against which a spring loaded
piston is pressing radially. Thus, any
independent change of the delivery volume
will be prevented. At the same time, the
latching serves as a measure for setting the
delivery volume. Six latches equal one
rotation of the adjustment nipple and a
reduction of the nominal delivery volume by
33%. 14 latches (minimum) equal a delivery
volume reduction down to 25% of the
nominal delivery volume.

The element with a piston diameter of
8 mm = 0,15 cm³/stroke is marked with a red
ring (see fig. 1).
Installation of pump elements:
If another pump element is to be installed in
the lubrication pump subsequently, proceed
as shown in the drawing on the right:
Insert pump element at an upwards
inclination into the locating hole with the
plunger pulled out about half way. To
facilitate installation and putting into
operation, fill the bore taking up the plunger
with grease. Bring into horizontal position
and screw in only after the plunger head
abuts the pressure ring and engages in the
groove of the pressure ring.
Reservoir / level monitoring:
When using a "K" sequence piston, the
utilisable reservoir capacity decreases by
approx. 2,5l.

The "empty" signal will be intermittently.
Connection scheme:
The function of monitoring "C" has been
tested with mineral oil-based lubricants
successfully. In case of special lubricants,
suitability needs to be tested.
The grease inside
the reservoir causes
to lift up the actuating
flap (1) upon rotation
of the pump driving
shaft. No signal will
be given.
In case of an empty
reservoir and a rota-
ting pump driving
shaft the actuating
flap (1) will intermit-
tently attenuate the
proximity switch
(3).
In case of full reservoir, the actuating flap,
depending on grease penetration, may fall
during standstill and attenuate the initiator
(3).
Therefore, when evaluating the initiator
signal, it should be ensured that the ini-
tiator signal is evaluated delayed (by
approx. 10 sec).
