PP - Air/hydraulic pumps (series 1000)
PP-1000 air/hydraulic pumps are very compact one-stage pumps that work in any position, horizontally or vertically thanks to a rubber bladder built in to the tank. The pumps can be operated by hand or foot.
• High oil flow.
• Easy to fill and check oil level.
• Safety valve prevents overfilling the tank.
• Return oil line can be connected to oil filler hole.
PP70-1000 - for those pumps we recommend gauge AMT801 and gauge adapter AVM204. Other combinations of gauge and gauge adapter are however possible.
PP70-1000/LS201, PP70-1000/LS250 - PP70-1000 pumps are available in a pre-mounted version with 2 m or 2,5 m hydraulic hose, quick coupling (AQI7) and swivel coupling (ASE10).

Axial piston units are available in the form of pumps and motors in bent axis design or swashplate design for medium- and high-pressure ranges. They are the main components in the hydrostatic transmission. Compact size and high power density, economy and reliability are characteristic advantages which speak for the use of hydrostatic transmissions, together with the fact that they meet the demand for high speed and high torque, as well as optimum efficiency.
Characteristics:
- Open and/or closed circuit
- Displacement 5 to 1000 cm3
- Nominal pressure up to 450 bar
- Maximum speed up to 11,000 rpm
- Maximum power output 933 kW
Our versatile transmissions for mobile applications can be combined in a variety of ways with pumps, motors and open or closed loop control devices to offer the optimum design for every drive application and every power range.
Key advantages:
- Infinitely variable speed setting at fixed or variable input speed
- Immediate, jolt-free change in direction of rotation
- Simple, ergonomic operation
- High turnaround
- Automatic torque conversion
Axial piston pumps and motors are used for the travel drive and working hydraulics in a wide variety of mobile machines.

INDUSTRIAL PUMP
Leduc axial pumps are of the stationary cylinder block type. The inclined
swashplate is turned by the drive shaft, thus causing the alternate movement of the pistons. Fluid enters the pistons via a groove in the swashplate and is expelled via check valves, self–priming if required. The forces on the shaft are taken up by bearings. The pump body is made of forged steel.
A precise calculation of the stability of the films of fluid between the friction surfaces means that there is virtually no wear on the moving parts.

Why use a variabledisplacement pump?
•precise control of all movements ;
• multi-function capabilities: simultaneous movements, all independant
of load ;
• avoid problems of fluid overheating ;
• reduce energy consumption.
Variable displacement : only advantages !
Installing a TXV variable displacement pump will transform your hydraulic equipment. Slow or rapid movements are done with precision, to the constant adjustment of pump flow rate. The TXV ranges are the result over 40 years' experience in hydraulic pumps. HYDRO LEDUC, France's leading pump manufacturer, is proud to present these high performance products.

Capacity to control minimum displacement
The DELTA pumps are designed to regulate flow from maximum flow to flow cancellation mode. However, some applications require a minimum outlet flow to be maintained, regardless of how flow is controlled from maximum to minimum.
Capacity to have a high speed rotation
The rotating speed of the DELTA pumps depends on:
• flow supplied by the pump,
• the fluid viscosity,
• the pressure at inlet point of the pump.
For applications at higher speeds than those indicated, please contact our Technical Department with details of these parameters, to enable us to advise what can be recommended.
■ Features of DELTA pumps
The DELTA pumps are equipped with a maximum displacement control.
