3 Description eatures and general description The DPX system doses lubricant with a progressive piston movement. very piston controls the following one in a sequence obtained through a single delivery flow. This system is highly qualified for dosing oil and grease to one or more journals or bearing. ach piston is in series with the component before or the one after it and therefore malfunctioning of one of these causes stopping of the sequence and consequently inhibiting of the system. This inhibition occurs also during any external clogging or when unused outlet are plugged. In order to check the entire distribution process, it is enough to apply a single visual or electrical control. The pump flowrate is fractionable when the doser blocks are arranged in cascade. master block can supply one or more progressive doser. Those doser can, in turn, supply another block of dosers. It is recommended to have no more then two cascades after the master for compressibility and aerations reasons. ny further addition can cause irregular flow, especially using grease or low flow rates. 3

5 Outlets Outlets How to join/separate outlets ig.1 One separation dowel (IG.1) divides the lubricant through the two outlets. In order to have just one outlet with the double discharge remove the dowel and close one of the outlet with the plug (IG.2). ig.2 Uscite Somma delle portate Utilizzando il tappo si convoglia il lubrificante nell uscita sottostante. Nell'esempio (fig 3) viene utilizzato il tappo nell'uscita e il lubrificante viene convogliato nell'uscita, analogamente un tappo sull'uscita G che convoglia il lubrificante in I. I tappi in serie nelle uscite D, e H convogliano il lubrificante nell'uscita L Per soluzioni che prevedono una combinazione dei tappi e è necessario rivolgersi all'ufficio tecnico IL. 200 mm³ 200 mm³ 0 mm³ 0 mm³ D 400 mm³ 0 mm³ G 0 mm³ 0 mm³ H I 400 mm³ 800 mm³ L ig.3 5

10 Shut-Off valve DPL Shut-Off V /.115/.230 SHUT O valves V-2 are made of a special N 2-ways solenoid valve and of a modular base that can be directly assembled on the DPL inlet. V-2 valve is the essential element in order to transforma a standard progressive system into a sectioned system.

11 ycle control Visual pin The visual pin shows the piston movement, monitoring the proper operation of the entire system. Inductive control In this control a proximity switch is housed in a composite block. The piston opens and closes the contact as it moves into its operational seat. They are usually used in cycle control systems where they can count up to 300 movement for minute. lectrical Data Voltage 6-30 V D Outlet current Max 200 m urrent < 22 m Operating temperature from - 25 to +70 Protection IP 67 Sensor housing Stainless steel Sensor block Pet-G onnection M8x1 - M12x1 onnection cable codes lectrical connection Length M8x1 Straight M12x1 90 M12x1 Straight 5 m m m Sensor kit codes M8x M12x

13 Memory sensor Pressure pin indicator (with memory) These indicator are usually for overpressure control on primary and secondary lines. In the eventuality of a pressure higher then expected, the pin indicator moves out. It remains in position until the release lever is manually actuaded. We suggest to discover the reason and the location of the fault before actuating the lever.
