Econamic & Ecomatic 

Customised public utility hydraulic design

Available as constant hydraulic system or as load-sensing hydraulic system.

Econamic hydraulic systems deliver constant volumes of oil to a maximum of two different hydraulic circuits. For instance in winter operation a snowplough and a spreader unit can be supplied. A tandem pump directly flanged on to the engine power take-off drive of the vehicle then supplies the front plough with a maximum of 20 litres of hydraulic oil, and the second circuit for the spreading unit with a maximum of 40 litres. Each of the two hydraulic circuits is thus fully dedicated to its respective consumer. Of course the Econamic municipal hydraulic system is also available as a single-circuit hydraulic system. The valve block and the black box for the controls are installed in an enclosed equipment cabinet. On request, a combination equipment cabinet with an integral hydraulic tank is available.

Ecomatic hydraulic systems on the other hand use load-sensing technology. They incorporate a hydraulic control system which matches the delivery volumes precisely to the instantaneous demands of one or more consumers. This allows it to supply snowploughs, spreader units, side ploughs, front-mounted sweepers, top-mounted tippers, cranes etc. The hydraulic supply to the entire LS system is provided by an axial piston-type variable displacement pump which also is directly flanged on to the engine power take-off drive of the vehicle. If desired, a clutch can be installed between the power take-off drive and the variable displacement pump, so that the drive can be disconnected from the pump. The axial piston-type variable displacement pump permits any delivery volume in the lower engine speed range. The advantages of the proportional valve technology used lie above in the reduction of the noise level thanks to low engine speeds, the reduction in operating costs and also the flexible sandwich design.
