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 micropumps, hydraulic micromotors and valves, which all have proven capability of operation in extreme conditions of temperature and environment. Based on a “standard” range, customized models can also be offered, with a choice of:

- drive shafts;

- inlet and outlet ports;

- flanges or threaded connections.

Furthermore, for your specific projects, HYDRO LEDUC offers complete integrated pump-motor units, and complete power packs, designed and built to meet your specifications.

Let us surprise you with the innovative solutions possible from HYDRO LEDUC!

■How to determine your LEDUC pump

1. Conversion table imperial/metricValue SI unit Imperial unit ConversionDisplacement / Volume mm³ Cu.in (in³) 1 cu.in = 16 387 mm³Torque N.m Lbs.ft 1 lbs.ft = 1.356 N.mLength mm In 1 in = 25.4 mmPressure bar PSI 1 bar = 14.5 PSIPower W HP (horsepower) 1 HP = 746 WFlow cm³/min USgal/min (ou GPM) 1 USgal/min = 3785 cm³/minWeight kg Lbs (pound) 1 kg = 2.2 lbs

2. Determining the pump displacement required2.1. If we know the flow Q and motor speed N, we can calculate the required pump displacement cyl:

cyl = QN x 1000 cyl =

QN x 231

2. 2. Choose the closest displacement pump in our catalogue, then adapt flow or rotating speed depending on the application:

oror

Q = cyl x N1000

N = Q x 1000

cyl

Q = cyl x N

231

N = Q x 231

cylFor your most demanding applications, HYDRO LEDUC can make the exact displacement to suit the application. Please contact us.

3. Calculating actual flowAll hydraulic pumps have an internal leakage which is proportional to working pressure. This leakage volume is quantified by the volumetric efficiency µvol.. Actual flow is calculated with the following formula:

Qreal = Q x µvol.

100Qreal = Q x

µvol.

100

Volumetric efficiency µvol as a function of working pressure is given for each fixed displacement pump. The values shown are for standard usage (room temperature and mineral-based hydraulic fluid), and will vary by application

4. Calculating torque calculationThe torque Cth absorbed by the pump is calculated from its displacement cyl and pressure P

Cth = 1.59 x cyl x P

100 000Cth =

cyl x P75.4

Increase torque Cth by estimated mechanical efficiency µmeca. to get actual drive torque Cu:

Cu = Cth x 100

µmeca.Cu = Cth x

100µmeca.

Initially, use 80% as estimate of mechanical efficiency.

5. Calculating power on motor shaftMotor power W is calculated using torque Cu and rotating speed N.

W = Cu x N9.55

W = Cu x N5254

6. Quick calculation formulaAn approximate value for power absorbed by the pump can be calculated using the following formula:

W = cyl x P x N

480 000W =

cyl x P x N317 000

■Definition and main applications

LEDUC micro-hydraulics offers a complete and original design wherever consider-able force is required within a small space envelope with very limited output power available.Examples of particularly demanding applications already mastered include: - providing 13 tons of crimping force for a handtool barely larger than a cordless drill;

- ensuring the operational reliability of oil tools for exploration and measurement while drilling, where the entire hydraulics envelope may fit into a housing of no more than 1.18 to 1.57 in (30 to 40 mm) in diameter;

- 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.

Calculations in METRIC units are shown in blue and calculations in IMPERIAL units are shown in green

■Graphs (see page 12)

- Power consumption - Flow as a function of outlet pressure

ADJUSTABLE PUMPS (with factory set adjustment)The displacement of PBV pumps is adjustable as a function of outlet pressure, in order to limit power consumption.When outlet pressure is low, the pump operates at maximum flow. When outlet pressure increases, pump displacement and flow gradually decrease (see graphs on page 12).

Ins ta l la t ion and s ta r t -upMic rohydrau l i cs

All micro-hydraulic pumps and units are tested individually on specific test benches, to guarantee performance. However, once in your applica-tion, guaranteeing performance depends on how well the following guidelines are adhered to. The following recommendations apply to both micro-pumps and micro-motors.

■Before using a micropump

LEDUC micro-pumps are supplied in a storage fluid, to protect the components from corrosion. It is a mineral oil of general use, mixible in all proportions with most typical hydraulic fluids. 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. The direction of rotation is always determined by looking at the pump shaft; it is engraved on the housing:

CW: clockwise CCW: counterclockwise

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.

■FluidsMicro-hydraulic pumps and motors are generally used with mineral-based hydraulic fluids. However, new fluids are also compatible with most LEDUC pumps and motors: - Synthetic oils, - Biological and biodegradable, - Fluids with some water content.

LEDUC pumps and motors accept a wide range of viscosity. For extreme viscosity, the rotating speed and the inlet pressure of the pump must be adapted. Please ask our Technical Department.Whatever fluid is used, it is essential, to ensure a controlled cleanliness class during the start-up.We recommend the use of contamination class 15/14/12 according to ISO 4406 (equivalent to a class 6 according to standard NAS 1638 or lower).For all special applications, please ask our Technical Department. To enable us to assist you in your choice and to optimize your microhydraulic installation, we will ask you to advise: - The product will be required to operate at the working cycle (flow-pressure), - Type of fluid, viscosity and operating temperature, - Supply conditions (pressurization, design of inlet line), - The drive mode.

■Drive modesDirect drive (pump directly flanged onto the motor) is always the preferred solution.If another drive mode is used, please avoid any load on the pump shaft (axial or radial load).Considering the specificity of these pumps, please contact our Technical Department to check your project feasibility.

■Filtration

The cleanliness of the fluid is vital for hydraulic component, to run satisfactorily, and to allow optimal service life.As well as using fluid of the right cleanliness class (ISO4406 15/14/12), we also recommend fitting a 3-10 μm filter on the return line.LEDUC pumps can be supplied fitted with a 40micron protective screen, which avoids start-up accidents in cases where a contaminant (end of thread, tiny piece of hosing, flake of paint etc.) might get into the pump supply circuit.

■Installation precautions

Carefully clean and rinse the tank and all pipes and hoses to remove any contaminants that could damage the installation.

■Installation position (see figures at the bottom of the page)

Microhydraulic components can be used in any position. However, some installation positions can complicate the start-up (see the start-up part).Horizontal position, submerged in oil (fig.1): bleeding will happen naturally. After filling, wait several minutes before starting up.Horizontal position, tank above the pump (fig.4): the pump will bleed itself in about one minute. Start up and run the pump slowly at first, until the air is purged from the fluid.

■Supply line

The inlet line must be as direct as possible, and well dimensioned to avoid any pressure losses. Avoid all curves that could cause the fluid flow to slow down, or cause an air trap.Inlet line performance can be improved by pressurizing the tank.HYDRO LEDUC’s is technical department can help you to design your inlet circuit.

■Start-up

The pump must be filled with oil and the circuit bled before starting the pump. The best bleed procedure to guarantee pump priming is as follows: - -when possible, position are of the inlet ports facing up, to evacuate air; - it is good to turn the pump slightly during bleeding process, to displace the air pockets which may have formed during filling; - initial start-up should be at low speed (around 500 rpm). If this is not possible (constant speed motor), operate on/off intermittently. - initial start-up must be without load on the bearing. Then apply load gradually if possible.

HYDRO LEDUC can fit its pumps with a self-priming system, adapted to difficult operating conditions (vertical position, risk of interruption of supply flow…). Please ask us.

■Checking inspection

On start-up, check oil outlet flow is constant and regular. Fluid must not be emulsified, if it is, restart purge process.

■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 1000 hours of operation (depending on the contamination and the type of fluid).
