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.
