Lubrication system pumping station DC41

FARVAL DUALINE DC41 and DC42 systems hâve been designed to meet the rigorous requirements of heavy industry. They can supply either oil or grease to such installations as bar mills, billet mills. blast furnaces, and sintering machines. The two systems have much in common. They use many of the same parts and have many similar operating characteristics. They differ in the way they alternately pressurize and relieve (reverse) the two supply lines aswell astheway they control maximum system pressure and end the lube cycle. On DC41 systems (see Fig. 1.1), reversai isby a solenoid reversing valve and on DC42 systems (see Figs. 1.2 and 1.3) by a hydraulic reversing valve. On DC41 systems. pressure is controlled by a pressure switch (one is installed in each line) that actuates the reversing valve and stops the pump motor when system pressure rises to its setting. On DC42 systems, pressure is controlled by the reversing valve. The valve opens a micro switch stopping the pump motor when system pressure rises to its setting. Each system has a timer control tailored to meet its spécifié requirements. See Bulletins DL-1200 and DL-1210 for reversing valves and Bulletin 1800G for accessory equipment.
