6. Unpacking and Installation
6.1 Unpacking
Once you have identified the place suitable for installation, open the packaging, remove the pump
and check to ensure that it has not suffered any damage during transportation and storage. The
packing material does not require special disposal precautions as it is in no way dangerous or
pollutant. For disposal, refer to local regulations.
6.2 Installation of the Pump
Place the pump and fasten it to its support by using the appropriate Ø9 mm holes (0.354 in),
with 2 suitable screws.
Assemble the pump in such a way that the cartridge housing and the bleed valve are easily
accessible.
Leave at least 100 mm (3.94 in) as a perimeter distance with respect to other equipment or
barriers to prevent access to the pump.
Assemble the pump at “labourer height” in order to prevent abnormal posture or possible
impact.
Do not install the pump submerged in liquids and/or in aggressive environments.
Do not install the pump in environments where there are explosive or flammable mixtures.
Do not install the pump near heat sources.
Verify that the grease used is fit for operating temperatures, especially at temperatures
below 0° C. If in doubt, contact our Sales Technical Office for the correct choice of
lubricant.
6.3 Hydraulic Connections
The connection with the hydraulic oil is marked with “A” and its size is G1/4”. The connection with
the lubricant outlet is marked with “B” and its size is G1/4”.

7. Instructions for use
7.1. Measures to be taken prior to start-up
The unit may be put into operation by specialized personnel.
Using the pump submerged in fluids or in a particularly aggressive or explosive/flammable
environment is prohibited unless it has been prepared ahead of time by the supplier for this
purpose.
Use gloves and eye protection as required by the lubricant safety data sheet.
DO NOT use lubricants that are aggressive to NBR gaskets. If you are unsure, contact the
Dropsa S.p.A technical office for a detailed list of recommended lubricants.
Never ignore health hazards and always follow sanitary regulations.
Always use suitable piping for the operating pressure.
Check the integrity of the pump.
Ensure that the pump operates at operating temperature and that the pipelines are free of any
air bubbles.
To determine the maximum operating pressure, it is necessary to know the pressure drop of the
pipeline connected to the pump outlet, depending on the length, temperature and type of
lubricant.
Depending on these variables to achieve a proper supply to the delivery point, you must always
ensure that the pipeline pressure loss plus the pressure required at the lubrication point does not
exceed the maximum pressure supplied for pump delivery.

7.2. Lubricant Filling
The pump is supplied without a cartridge and completely empty. The reservoir can house 400 cc
cartridges.
To fill it, you must proceed as follows:
Cartridge Pump
Step1:
Unscrew the reservoir
from the base
Step2:
pull the reservoir rod
upward
Step3:
Remove the cartridge cap
Step4:
Insert the cartridge in the
reservoir
Step5:
Remove the cartridge tear
cap
Step6:
Screw the cartridge onto
the pump all the way,
tightening it moderately
Step7:
Press the tab on the upper
part of the reservoir and put
the rod back in

10
7.3. Flow capacity adjustment
For the adjustment of the flow rate, you must proceed as follows:
Unscrew the locking nut
Tighten or loosen the adjustment screw to achieve the desired flow rate (see diagram below).

8. Problems and Solutions
Below is a troubleshooting table where the main faults, probable causes and possible solutions to
be carried out immediately are indicated (contact Dropsa).
In the event of doubts and/or irresolvable problems, do not search for the fault disassembling
parts of the pump, but rather contact the Dropsa Technical Office.
TROUBLESHOOTING TABLE
FAULT
CAUSE
REMEDIAL ACTION TO BE TAKEN
The pump works but lubrication
does not arrive at the lubrication
points.
Lines disconnected.
Check the condition of the lines and the
relative connections to the fittings. Replace
worn lines.
The lubricant is distributed to the
lubrication points in irregular
doses.
The pump is not properly
connected to the lubrication points.
Check the dosages with the system diagram.
The pump does not dispense the
correct quantity of lubricant.
Air bubbles in the hydraulic control
circuit.
Use the bleed screw located on the upper part
of the pump to eliminate the air.
The pump does not dispense
lubricant.
The reservoir is empty.
Replace the cartridge.
Air bubbles in the lubricant.
Disconnect the primary pipeline from the
connection to the pump. Activate the pump
according to the operating cycle until lubricant
comes out of the connection without any air
bubbles.
Air bubbles in the hydraulic control
circuit.
Use the bleed screw located on the upper part
of the pump to eliminate the air.
Use of unsuitable lubricant.
Replace the inserted cartridge with one with
suitable grease.
Operation may only be carried out by Dropsa specialised personnel.
9. Maintenance Procedures
The pump does not require special tools for any check and/or maintenance operations. In any
case, it is recommended to use suitable equipment and personal protective equipment (gloves,
protection goggles, etc.) that in good condition in accordance with applicable regulations to avoid
injury or damage to parts of the pump.
The unit has been designed and built in such a way that it requires a minimum level of required
maintenance. Nevertheless, it is recommended to always keep the body of the equipment clean
and periodically check the tube joints in order to be able to readily detect any leaks.
ATTENTION: Make sure that hydraulic feed is disconnected prior to any maintenance or cleaning
operation.

9.1 Scheduled Maintenance
The following table lists the periodic inspections, the frequency and the intervention that the
maintenance will have to carry out in order to ensure the efficiency of the system over time.
3.3. Warning of Residual Risks
in order to prevent any dangerous condition for personnel or damage to the MACHINE caused by
residual risks, in other words, those risks that remain despite all the devices adopted, or from less
evident potential risks, the MANUFACTURER urges operators, maintenance personnel and all
personnel in charge of the MACHINE to strictly adhere to the warnings indicated on the following
pages.
CHECK
FREQUENCY INTERVAL
INTERVENTION
Attachment of the lines
After the first 500 hours of
operation
Every 1500 hours of operation
Check the joint fittings.
Check the fastening to the parts of the machine.
10. Disposal
Do not dispose of polluting components in the environment during pump maintenance or in case
of demolition; refer to local regulations for correct disposal. Upon demolition of the pump, the
identification label and any other document must be destroyed.

13. Handling and Transport
Before shipment, the pumps are carefully packed inside a cardboard box. During transport and
storage of the equipment, pay attention to the direction indicated on the box. Upon receipt, check
that the packaging is not damaged and store the pump in a dry place.
14. Precautions for Use
Flammability
The lubricant generally used in the lubrication circuits is not inflammable fluid. However, it is
imperative to take all necessary steps to prevent it from coming into contact with very hot
parts or naked flames.
VALVE
Before any operation, check for the absence of any residual pressure in all branches of the
lubricant circuit, that could cause spurts of oil in the event that fittings or components are
disassembled.
Noise
The equipment does not emit noise exceeding 70 dB (A).
ATTENTION: The warnings on risks using a lubricant pump implies must be carefully read. The user
must be familiar with operation through the Operation and Maintenance Manual.
14.1. Lubricants
A table is shown that compares the NLGI (National Lubricating Grease
Institute) and ASTM (American Society for Testing and Materials)
categories for greases, limitedly to the values that involve the
OmegaPUMP pump.
For further information on the technical characteristics and the safety measures to adopt, see the
Product Safety Data Sheet (Directive 93/112/EEC) related to the type of lubricant selected and
supplied by the manufacturer.
NOTE: The pump is designed to work with maximum NLGI 2 grade lubricants. Use NBR gasket compatible
lubricants. Any residual lubricant inside that was used for assembly and testing is NLGI 2 grade.
