1. INTRODUCTION
This operation and maintenance manual refers to the Bravo lubrication pump, and includes essential information
regarding correct operating and safety procedures design to ensure safe and reliable operation of the unit.
You can obtain the latest release of this document by contacting a Dropsa sales office or distributor or by visiting us on the
World Wide Web at http://www.dropsa.com.
It is important that this document is read and maintained in a place that anyone operating the Bravo is able to consult it if
necessary.
2. GENERAL DESCRIPTION
2.1 CENTRALIZED LUBRICATION –GENERAL OPERATING INFORMATION
Centralized lubrication systems are designed to provide oil or grease for lubricating fiction points on industrial and mobile
machinery. Such systems considerably reduce the cost of maintaining machinery on which they are installed, eliminating
machinery downtime caused by poor lubrication as well as prolonging the life of the machinery in general. Additionally, a
centralized lubrication system allows difficult to reach lubrication points to be
lubricated at frequent intervals that would otherwise be hard to access under normal
conditions.
The diagram on the left shows a typical schematic of a simple centralized lubrication
system.
The main components are:
A –Electric Pump with Reservoir (eg. Bravo Pump).
B –Primary lubrication line for distributing grease.
C –Distributor elements that meters grease into a number of points.
D –Secondary tubing that delivers grease to the lube point.
The pump feeds a distributor element that shares and doses the ratio of grease between the several friction points.
Bravo Pump has been designed to provide the pumping solution for such systems used in industrial and mobile
applications for greases up to NLGI 2 consistency and Oils with minimum 46cSt.
2.2 BRAVO ELECTRIC GREASE PUMP
BRAVO is an electric piston pump with the pumping element operated from a camshaft connected to a reducing gearbox.
It can be fitting with up to 3 pumping elements (1 standard) which are available with or without an integrate pre-set
bypass (pressure safety valve).
The Bravo also has a modular build reservoir that can be supplied in 2, 5, 8 litre capacity. Additionally a minimum level
sensing device is fitted as standard at the base of the unit. As an optional accessory, a remote button with light is
available.
Bravo is available as both with an integrated automatic control board that controls and monitors the pump and lubrication
cycle or a manual version where the pump motor is controller externally by applying and removing power.
The main body of the pump is made from high performance robust plastic and is compact in size designed to withstand
tough environments.
The grease version of the Bravo includes a stirrer device with a reservoir wiper that help to eliminate air present in the
grease and facilitate pumping even at lower temperatures.
The direct-current geared motor drive arrangement, is controlled remotely in the manual version or via the built in control
system in the automatic version. There are three operating modes for the controller version. (Refer to 5.1 paragraph)
3. PRODUCT IDENTIFICATION
On the side of the pump there is a label that indicates part number of the product, operating voltage and basic
characteristics.

set).
When powering on the system or when pressing the RESET button the display will the firmware version of the unit
for 2 seconds.
For all modes the Prelube parameter determines if the pump starts in a lubrication cycle when it is set to ON.
Cycle and Pause inputs consider one complete cycle when the input returns to its original state at the time of cycle.
For example, if the switch is in the ON state at the start of the lubrication cycle then it must change state to OFF,
and then back to ON to count as one cycle.
Pump operates when external signal is given. No monitoring
NOTE: To modify the operating parameters repeats steps 2 to 5 for all necessary values and then follow
step 6 to save and exit.
During programming mode, if no button is pressed for 20 seconds, or alternatively UP or DOWN
arrows are held for 2.5 seconds, this will exit Programming mode without saving the values.
