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.
