1. INTRODUCTION

This user and maintenance manual relates to the MiQueL EXT.
Using this pump means that oils and greases can be distributed within lubrication systems even at high pressures of up to 400
bar (5880 psi).
The latest version may be obtained from the Technical-Commercial Office, or by consulting our web site

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

Operation
The system consists of a pressurised lubricant tank, one or more mixture regulation modules, pipes and spray nozzles (see
hydraulic diagram below).
The lubricant is sent to mixing valve  through an external pump or a pressurised reservoir.
Each module has oil
and air
be managed independently between the different modules using a mini solenoid valve
control valves
on the module. The module has a compensation valve
constant as the inlet tank pressure and outlet counter-pressure varies.
The lubrication pipes can be traditional or coaxial. In the latter case, the lubricant and nebulisation air are transported
separately to the nozzle. The piston

Spray nozzles
When traditional pipes are used, the air and oil are already mixed when they arrive at the nozzle.
If coaxial pipes are used, the nozzle mixes the air and oil at the point to be lubricated. The lubricant is atomised in minuscule
particles by the air flow that passes in front of the oil outlet hole.
The geometry of the nozzle is designed based on the type of spray to be obtained (conic, blade-shaped, etc.).
Advantages
Easy to install on the machine
Reduction in tool wear
Improved surface finish on the part
No lubricant residuals left on the part when the work is complete
The nozzles do not drip after being turned off
Large spray range (up to 300 mm)
Greater safety and environmental hygiene at the workplace
