<p>Variable (10) and fixed ratio 100 dispensing systems are disclosed. Each pump (12) is powered by a DC motor (14) spinning a gear pump (16) which is immersed in a hydraulic power pack (18). The power pack 18 output feeds a hydraulic linear motor (20) where its direction is controlled by a two output reversing valve (22). The hydraulic linear motor (20) drives one or two material pumps (24) which are mechanically attached to the hydraulic pump (12). The pressure and/or flow outputs of the material pumps (24) are controlled by altering the torque output of the DC motor (14) using a custom designed motor control module (MCM) (26).</p> |
