6. Start-up
Prior to putting into operation, fill the lubricant reservoir. Filling can be effected manually or be means of a
filler pump. A filler pump connection at the pump housing can be attached upon request. Pay particular
attention to cleanliness of medium to be filled-in.
Prior to connecting the feed lines, the pump shall work in nonpressurized condition until lubricant is
emerging from the outlets. The rate of delivery can be adjusted by means of set screws (19) at the
individual delivery pistons. These setscrews become accessible after removing the dust cap (20). The
setscrews to be adjusted have to be unscrewed up to
"zero rate of delivery"
and, then, to be screwed-in
again until reaching the rate of delivery desired. Finally, lock all setscrews by means of hexagon nut (21)
provided. After completion of setting work, screw-on the dust cap again.
Fastening of central lubrication pumps is ensured via four fastening bores at the housing.
The pipelines are connected via screwed fittings according to DIN 2353. The thread in the pumping units
for connecting the feed lines is M 14 x 1.5.
Feed lines having an outer diameter of 8 or 10 mm can be connected.
ATTENTION
For the first commissioning of the pumps, it is essential to fill in addition to the lubricant tank also the pump
case with the lubricant to be delivered. The pump ZP5000 are provided with a conical head lubrication
nipple A R1/8 DIN 71412 with the help of which this can be realized easily. The pump with pumping
mechanism, one can also make filling by removing the blind flange. It is absolutely essential to take care of
cleanliness. The pumping mechanisms are not self-priming. The higher is the consistency of the lubricant to
be delivered, the more disturbing are air inclusions in the pump case during commissioning.
Prior to the connection of the lubrication point lines, the pump has to work without pressure until lubricant
escapes at the outlets. Care has also to be taken that this process can take differently long periods of time,
depending on the reduction of the pump.
To shorten the commissioning process, longer lines can be prefilled prior to their connection to the pump.
Should it be necessary, contrary to the operating conditions, to fuse outlets, non-return valves are to be
provided in the outlets concerned.
This additional information refers to the arrangement of the outlets at the pumping mechanisms and the
arrangement of the pumping mechanisms in the pump cases.
Central lubrication pump ZP5000 can be equipped with one pumping mechanism ( 8 outlets) or 2
pumping mechanisms (per 8 outlets) according to requirements. The version with one pumping
mechanism has the same on the right side of the pump.
In the case of pumps the number of outlets of which exceeds that of a pumping mechanism, the even-
numbered number of outlets is apportioned in equal parts to both pumping mechanisms. When it deals
with an uneven number of outlets, the right pumping mechanism has always one outlet more.
