  • These pneumatically actuated piston pumps are designed for periodically operated, single-line lubrication for industrial applications, like expanded metal machinery or textile machinery.

    The P-Series feature a range of pump types compatible with oil and fluid greases.

    • Simple handling
    • Optional low-level control for reservoir

    • System overview

      Compressed air connection
      All pumps within the range are to be connected to a compressed air supply line.

      Reservoir
      Pumps in the P-Series are available with or without a lubricant reservoir. Reservoirs can be located above or below the pump and made of high quality plastics or steel, depending on the model.

      Filling cap or nipple
      Depending on the pump type and what kind of lubricant is used, P-Series pumps are equipped with a filling cap or filling nipple to re-fill the reservoir. The filling cap and nipple both have an integrated filter to filter out contaminants of the lubricant.

      Level monitor
      The P-Series pumps can be delivered with or without a low level monitor to monitor the filling level in the reservoir. A special level monitor is available for systems that are going to be used with fluid greases.

      When the level of lubricant is too low, the signal of the low level monitor can be used to switch off the pump or as a visual or acoustic warning-signal.

      Outlet
      The P-Series pump has one outlet which transfers the lubricant to the metering devices. The most common combination is to use the system with the DVB-1-2-3 or 231-DV single-line metering devices.

      Working principle
      Lubrication starts when the piston is pressurized. The compressed air is adjusted in a way that the pressure relief valve only opens when all metering valves finished the process. This ensures that all metering valves supply enough lubricant to the lubrication points.

      When the 3/2-way solenoid valve for the air supply switches over, the piston is pushed into its original position by the pressure spring. Pressure in the main line is relieved to approx. 1 bar by the relief valve and the metering valves restock the lubricant for the next lubrication pulse. At the same time, the lubricant is sucked out of the reservoir for the next stroke.

      The metering device’s total delivery volume should not exceed 60% of the pump’s delivery quantity
