LK Series Metering Pumps

The LK Series metering pumps are motor-driven, mechanically-actuated diaphragm metering pumps. This larger Series can achieve outputs up to 856 GPH (3240 l/h) and maximum pressures of 220 PSI (1.5 MPa). The LK Series metering pump is ideal for large chemical feed applications in a wide range of fields, including water treatment, chemical process, agriculture, mining and paper.

The LK series offers a variety of sizes to fit a range of small to very large injection flow rates. Several material configurations and flexible motor options combine to satisfy a multitude of applications.

The LK series has a discharge accuracy (repeatability) that is within ±2% FS. Reliability has been enhanced with the improvement in the linearity of the stroke and the discharge ratio of each stroke.

Key Benefits:

  • High Performance & Versatile Design - The LK series has a discharge accuracy (repeatability) that is within ±2% FS. Reliability has been enhanced with the improvement in the linearity of the stroke and the discharge ratio of each stroke.
  • Drive - The heart of the LK is the dual-cam drive with a built-in worm gear type speed reducer. This compact & rigid mechanism, provides maximum wear resistance in continuous operation over long periods of time.
  • The LK-A, LK-B, and LK-C series pump are designed to be fit with IEC general-purpose, vertically mounted TEFC outdoor-use motors, providing different voltage and enclosure options, including VFD-ready and explosion-proof designs.
