Дозирующие устройства высокого давления QSL

QSL High Pressure Dosing Devices

For single-line lubrication systems

QSL metering units are designed for a pressure of 300 bar. As a result, NLGI grade 2 grease can be pumped without any problems at sub-zero temperatures. All metering units operate independently. This means that if one metering unit becomes blocked or malfunctions, all other units will continue to dispense lubricant. An indicator pin at the top confirms the proper operation of each metering unit.

Technical characteristics and advantages

  • Suitable for use with mounting plates with 1–6 channels, depending on the number of lubrication points. Mounting plates must be ordered separately.
  • Corrosion-resistant coating, black chrome or nickel plating surface
  • Each indicator pin provides visual control of operation
  • Easy disassembly for inspection or replacement
  • Controlled via main pipeline

Application areas

  • Renewable energy sources
  • Construction equipment
  • Mining and mineral processing industries
  • Small and medium-sized equipment, industrial use
  • Trucks

    If the back pressure in the lubricant supply lines is ≥100 bar, or if several injectors are combined to supply lubricant to one lubrication point, use check valves with part number 223-12289-7.

Accessories

QLS dosing units use mounting plates with 1–6 outlets (for push-in fittings), tightened with a hollow screw with a G 3/8 thread for an O-ring seal. Mounting plates with a normal profile are available in steel. The G 3/8 main pipe connection is designed for 16 × 2 mm steel pipe. (0.63 x 0.08 inches) The lubrication line connection is designed for 4.1 x 2.3 mm plastic tubing (0.16 x 0.09 inches).
