1 Progressive distributor VPA-D Use: In progressive mode based central lubrication systems. The main features of WOERNER progressive distributors are as follows: Accurate proportioning volumes. Clear and precise arrangement of control channels in spite of small-size construction. Modular system construction. Quick fault remedy possible without having to loosen the pipeline. different proportioning volumes selectable in accordance with the lubricant required. Extremely long service life refined sliding surfaces. due to Pluggable monitoring elements can be replaced during operation. No proportioning decrease at the piston monitored. Technical data: Proportioning volume per cycle: 0,9...,7 cm³ Lubrication point connections at max.: 0 Operating pressure at max.: 0 bar Throughput volume: Oil at max.: Grease at max.: 000 cm³/min 00 cm³/min Delivery medium: Oil viscosity: > cp Grease: up to NLGI category Material: Proportioning block: Aluminium Internal parts: Steel Connecting plate: Aluminium Temperature range: C A = Mounting point at distributor (for viewing indicator and electrical functionality check) B = Mounting point for viewing indicator at distributor (if point A is occupied) D = DPA-D proportioning block H = Main line K = Proportioning volume distinctive number M = M8 fastening threads for mounting of auxiliary units (for example, see data sheet 08) R = APA-D connecting plate S = Mid fastening screw Number of outlets Length "a" Length "s" Weight [kg] -, ,70 -,0 70,0 0 9,80 0 9, , ,90 Mounting position: usually as needed Note: In case of heavy vibration or shock load, install the distributor such that piston axes are situated vertically to the main direction of shock impact. An optimum ventilation of the whole lubrication system is the precondition for its functionally safe operation. For quicker ventilation, the flow direction from bottom to top in the distributor is of advantage (inlet on bottom side). The distributor must not be "distorted". Therefore, when mounting it, always be careful that the supporting surface is level. Progressive distributor VPA-D 0.00 Postfach DE-978 Wertheim Replaces No. Page of EN EN

6 Main line Fig. Functional process fig.... : Monitoring of progressive distributors: Bypass line left-side I II Bypass line right-side The lubricant flows from the main line through the right-side ring groove of piston III as well as the bypass line (right) and to the left side of piston I and moves it into its home position. The lubricant displaced by piston I is ejected via the left bypass line through outlet no.. As for instance due to soiling, the flow through a lubricant point line may be prevented. This will cause a piston to get blocked. By virtue of the forced control as depicted in figures up to, the other pistons will be stopped as well. Due to this configuration, the proportioning at all outlets of the distributor can be monitored by means of a sensor at one piston only. III Fig. Mounting note: I Fig. After shifting of piston I, lubricant flows to the left side of piston II and pushes it into its right-side home position. The displaced lubricant is ejected via outlet no.. The pistons are provided with an extremely small fitting clearance. Therefore, the pistons, after the dismantling of a distributor, must never be interchanged. Formula for calculating the lubricant available per lubrication point After shifting of piston II, lubricant flows to the left side of piston III and pushes it into its right-side home position. The displaced lubricant is ejected via outlet no.. A progressive distributor allocates the delivered lubricant to the individual lubrication points in forced order. Due to the functional process as described herein, a safe proportioning is ensured. II The lubricant q i delivered to a lubrication point i can be calculated as follows q i = K i (K +K +K...) Q Fig. After shifting of piston III, lubricant flows to the right side of piston I and pushes it into its left-side home position. The displaced lubricant is ejected via outlet no.. The continuation of that process is evidenced in the scheme depicted. Q = lubricant delivered to the distributor, K = distinctive number of the outlet i i III Postfach DE-978 Wertheim Page of EN

The safety and danger information stated in the safety data sheets of the substances used must be taken into account at all costs. Transportation of gases, liquefied gases, gases under pressure, vapours and liquids, the vapour pressure of which is more than 0, bar above normal atmospheric pressure (0 mbar) at the maximum admissible temperature, of easy inflammable or explosive media as well as transportation of foodstuffs is forbidden. Information on EU Directive 00/9/EC (RoHS) With Directive 00/9/EC of January 7, 00, for the limitation of the use of certain hazardous substances in electrical and electronic devices (RoHS) material bans come into effect from July 00 for electrical and electronic devices newly placed on the market for lead, cadmium, hexavalent chromium, mercury and brominated flame retardants. In its controls and switching devices, WOERNER only uses materials which fulfil the criteria of EU Directive 00/9/EC. To the extent that hexavalent chromium has been used as corrosion protection in the parts which we produce ourselves, it has already been replaced by other environmentally tolerable protective measures. The mechanical devices supplied by WOERNER are not affected by EU Directive 00/9/EC as they are appliances added or installed on "large-scale stationary industrial tools" (cf. EU Directive 00/9/EC, Annex IA). But as WOERNER is conscious of its responsibility towards the environment, we shall also use materials fulfilling the requirements of the Directive for devices not covered by EU Directive 00/9/EC as soon as they are generally available and their use is technically possible.
