Introduction
This use and maintenance manual refers to the CME pump.
Using this pump makes it possible to distribute oil or soft
grease in lubrication systems.
The latest version can be obtained by contacting the Sales
Technical Office.
The pump that this manual refers to must be used by qualified
personnel with basic hydraulic and electrical knowledge.
This use and maintenance manual contains important
information to protect the health and safety of personnel
who intend to use this equipment. This manual must be read
carefully and kept in good conditions so that it is always
available tooperatorswho intend to refertoit.

Application
At this point the pressurised lubricant will activate a release
valve, which will discharge the pressure inside the tank and
enablethevolumetricvalvestobefilled.
The process repeats each time the motor is switchedon and
off.
When the system is at rest, a check valve maintains the main
line at a pressure of 0.5/0.6 bar, thus preventing air from
entering.
Thestatuschangeofthepressureswitchduringoperatingtime
allows us to ensure there are no oil leaks in the main line.
The lack of lubricant inside the tank is signalled by a minimum
level sensor.
4. Technical specifications
The CME gear pump has been designed for use in single-line
or air + oil centralised lubrication systems. These systems use
the principle ofpressure and release pulses andthe lubricant is
sent to the volumetric valves or to the mixers positioned near
thepoints of the machine to be lubricated.
Any use other than described above shall not be in agreement

3. Operating principle
The pump sends pressurised lubricant through two side
outlets. This way the customer can connect the main pipe to
bothoutletsorto oneonly,pluggingtheunusedone.
When the motor is powered on, by an internal timer or an
externalPLC,thegearpumpisactivated, whichsends lubricant
from the reservoir to the distribution network through the two
outlets or through the selected one.
Pressurisation of the distribution network forces the volumetric
valves, whose metering chamber has been filled since the last
lubricationcycle,tosendthevolumeoflubricantinsidethemto
the points. Onceall thevalves have beenactuated, the pressure
will increase until a pressure switch is triggered and, after a
short time, it will be possible to interrupt motor operation.
