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.
 
These variable displacement pumps are axial piston
pumps. Pump displacement is proportional to the stroke
of the pistons. Displacement - and therefore flow - is
varied by changing the angle a of the swashplate.
Changing the angle a of the swashplate from maximum
to minimum enables pump displacement to vary from
maximum displacement to zero (flow cancellation).
