<p>A drive system for a reciprocating feed pump with pressure-dependent delivery of liquid, esp. for supplying filter presses, comprises a drive motor operating at constant speed. Between the drive motor and the pump there is an infinitely adjustable hydraulic transmission; the liquid pressure at the delivery side of the pump acts directly or indirectly upon the adjusting device which regulates the gear ratio of the transmission. Used for supplying filter presses, conveying liquids or filling tanks and vessels. Simple and reliable in operation. An optimum operating characteristic curve is obtd.</p> |
