1 microhydraulics maximum force from minimum power source

2 Microhydraulics makes it feasible to obtain several tons of force from a minimal power source within a very restricted space envelope. The techniques of microhydraulics allow simple easy-to-use solutions to problems that are often at or beyond the limits of traditional mechanical options. Hydro Leduc offers a complete range of micro-pumps which all have proven reliability of operating in extreme working conditions such as temperature, pressure, medium, and environment. Based on the standard range, customized models are also possible, with a choice of: drive shafts; inlet and outlet ports; flanges or threaded connections.

3 Choose your pump Displacements: from 0 to cu.in/rev (1.5cc/rev) Pressure: up to 14,500PSI(1000bar)

4 All types of inlet and outlet ports... even the one you need.

5 Different shaft ends... and yours.

6 Microhydraulics, the applications are virtually unlimited. Microhydraulics, the applications are virtually unlimited. Leduc micro-hydraulics offer a complete and original design wherever considerable force is required within a small space envelope with very limited power available. Examples of particularly demanding applications already mastered include: providing 13tonnes of crimping force for a handtool barely larger than a cordless drill; ensuring the operational reliability of oiltools for exploration and measurement while drilling, where the entire hydraulics envelope may fit into a housing of no more than 1.18 to 1.57in (30 to 40mm) in diameter, function during severe shock and vibration or in a corrosive environment; allowing oceanographic research drifters, deployed throughout the world s oceans, to resurface regularly, and above all with total reliability; guaranteeing the efficiency of guidance systems installed on the most modern fighter aircraft. The wide range of high technology industries concerned all require extensive know-how, and each new application tends to push through the limits of previous technology Such is Hydro Leduc s ongoing innovation challenge. transfer pump Corrosive fluids or fluids with very low viscosities are a problem in terms of the service life. Hydro Leduc has come up with a particularly innovative solution to this problem: the transfer pump. This recently patented technology involves separating the fluid to be conveyed from the fluid that actually transfers the pumping energy. The friction parts operate in a good lubricating fluid, whereas the parts which pump the fluid to be conveyed are subject to no friction. This new and major innovation makes it possible to use seawater, for example, as the operating fluid for marine applications. The transfer pump has been developed for displacements up to 0.061in (1cm 3 ) and for operation at pressures up to 4350PSI (300bar). Complete solutions Hydro Leduc offers custom designed hydraulic power packs. Apart from the pump that is the heart of HL s activity, our design team also has extensive knowledge and experience incorporating a pump, electric motor, valving, tank, pressure limiter, and those components which make up the pump s environment. Packages to suit the most diverse specifications can thus be developed. An effective partnership with an experienced team will guarantee the satisfaction of your technical requirement. The micro-pump axial piston type Developed and manufactured since 1970, Leduc axial piston micro-pumps offer pressure output up to 14500PSI (1000bar). Fixed and variable displacement models exist in displacements from just a few cubic millimetres per revolution to cu.in/rev (1.5cc) and are suitable for operating at temperatures between 122 F and F (-50 C and C). This axial piston design is particularly well suited to applications where diameter is critical. Hydro Leduc also offers a complete range of hydraulic components and industrial pumps, see page 22.

21 Installation Before using a micro-pump LEDUC micro-pumps are supplied in a storage fluid. This protective fluid is of AIR1506/MIL-H-6083 type and is compatible and mixible in all proportions with typical hydraulic fluids used of AIR3520/ MIL-H-5606 type. Before installing the micropump, simply empty the storage fluid, no rinsing required, then fill with your usual hydraulic fluid (chosen in line with our recommendations). Direction of rotation Most LEDUC micro-pumps are manufactured for a given direction of rotation (see table on page 9). CW: clockwise CCW: counter clockwise For those models made in one direction of rotation only, it is possible, on request, to produce the same pump for the other direction of rotation. Installation positions Fluids Micro-hydraulic pumps and motors are generally used with mineral-based hydraulic fluids. However, new fluids such as synthetic oils, biological and biodegradable fluids and fluids with some water content, are also compatible with most LE- DUC pumps and motors. Fluid should always be chosen within the recommended viscosity range. Cleanliness of fluid is critical to guarantee that pump and motor run correctly. HL recommends, for its micro-pumps to work in optimal conditions, to use a fluid to class 6. However, the pumps are capable of working well with fluids up to class 8 or 9. Please consult our Technical Department with details of your fluid and application, for our opinion and advice. For all special applications, please consult our Technical Department and, to enable us to assist you in your choice, advise: range of rotating speeds pump is to run at; viscosity range of fluid, as a function of extreme operating temperatures; supply conditions; type of fluid and compatibility with main types of elastomers, steels and copper metals. Drive modes The drive mode to couple pump to motor should respect the following basic rules: avoid producing any axial load on the pump shaft; if possible, avoid any radial load. A direct drive is always the best solution. Start-up, Maintenance All micro-hydraulic pumps and units are tested individually on specific test benches. Before shipping your pump, Hydro Leduc takes every precaution to guarantee the performance in terms of flow, pressure and speed. However, once in your application, guaranteeing performance depends on how well the following guidelines are adhered to: Filtration The cleanliness of the fluid is vital for hydraulic pump and motor to run satisfactorily. LEDUC pumps can be supplied fitted with a 40microns protective screen which avoids start-up accidents in cases where a contaminant (end of thread, tiny piece of hosing, flakes of paint etc.) might detach itself in the pump supply circuit. The fluid return line should, if possible, include a 3 to 10micron filter. Supply line Supply line should ensure as direct a connection as possible in order to limit pressure drop, and should avoid any high points. Installation precautions Carefully rinse the tank and all pipes and hoses to remove any contaminants that could damage the pump. Preparing to start-up 21 OUTLET The housing should be filled and bled with the pump at rest. INLET Fig. 1. Horizontal, pump and motor submerged. Fig. 3. Vertical pump submerged. Horizontal installation, submerged (figs.1 and 2) Turn one of the inlet holes towards the top and bleeding will occur naturally. After filling, wait several minutes before starting the pump. Vertical installation, submerged (fig. 3) The pump can be fitted with a self-priming device, in which case bleeding occurs naturally. Horizontal installation, tank above the pump (fig. 4) The pump will bleed itself in about 1minute. Turn the pump shaft very slowly, by switching the motor ON-OFF for example. Let the air-fluid mixture run out until there is no air left in. NOTE: Start-up should always be done with no pressure drop on output. Start-up Switch the motor on and check that flow is constant and regular. If it is not, drain the pump again. After several hours of operation, it is essential to check the tightening of the pump and all connectors. Fig. 2. Horizontal, only the pump is submerged. Fig. 4. Horizontal, tank above pump (pump with inlet collector and special housing). NB : The suction pressure of these pumps should always be positive. Considering the specificity of these pumps, please contact our technical department to check your project feasibility Maintenance LEDUC pumps do not require any particular maintenance and are designed to ensure long service life. However, the fluid in the circuit should be changed every 500 to 1000hours depending on the quality of the fluid and its cleanliness.
