HPV-02 Variable pumps for closed circuit operation


Representation of the hydraulic components of a closed-loop hydrostatic drive: Variable electro-hydraulic controlled pump HPV-02 E1 and fixed displacement motor HMF-02 plus filter, cooler, and oil tank. The function diagram and the circuit diagram show two types of cooling.

Linde high-pressure units are designed for excellent reliability and long service life. The actual service life of a hydraulic unit is determined by numerous factors. It can be extended significantly through proper maintenance of the hydraulic system and by using high-quality hydraulic fluid.

In order to guarantee long-term proper function and high efficiency of the hydraulic pumps, the purity of the pressure fluid must comply with the following criteria according to Linde Works Standard WN 51 210. High purity oil can extend the service time of the hydraulic system significantly.

Units of the HPV-02 series can be equipped with a pure charge pressure manifold or with a combined charge pressure and filter flange manifold. The following filter sizes are available, depending on the rated size of the unit. For further details about the mounting of the charge, pressure manifold sees section "Dimensions. Modular System"
