1. INTRODUCTION 

 

This  user  and  maintenance  manual  relates  to  the 

Dragon  X

.  Using  this  pump  means  that  oils  and  greases  can  be  distributed 

within lubrication systems even at high pressures of up to 70 bar (1015 psi).  
The  latest  version  may  be  obtained  from  the  Technical-Commercial  Office,  or  by  consulting  our  web  site 
http://www.dropsa.com

The pump subject of this manual must be used by qualified personnel with basic hydraulic and electrical knowledge. 
This user and maintenance manual contains important information about protecting the health and safety of the personnel who 
intend  to  use  this  apparatus.  You  must  read  and  look  after  it  carefully,  making  sure  that  it  is  available  at  all  times  for  the 
operators who intend to consult it. 

 

2. GENERAL DESCRIPTION 

 

The 

DRAGON X

 pump is particularly suggested due to its compact form and versatility when used with press lubrication systems, 

machine tools, reducers, guides, chains, etc.  
The 

DRAGON X

 pump has a built-in release valve* and can be used in the following types of systems: 

 

Lubrication systems with injectors and circulation systems with operating pressures <20 bar (290 psi) – system 01 

 

Lubrication  systems  that  have  "direct  response"  measuring  devices  with  operating  pressures  <  50  bar  (735

 

psi)  - 

system 33V. 

 

Progressive  lubrication  systems  and  circulation  systems  controlled  by  progressive  measuring  devices  with  operating 
pressures < 70 bar (1015 psi) – system 26. A non-return valve is available for this version. 
 

* The release valve aims to discharge the line pressure when the pump is not in activity. This valve ensures 0.5÷1 bar (7.2÷14.5 PSI) seal on the 
supply line, in order to avoid the emptying pipes during the pause time of the pump, that is between a lubrication and the next one. 

 
3. PRODUCT IDENTIFICATION 

 

There is a yellow label on the front of the pump tank that displays the product 
code and its basic characteristics.
