LK series Various types and materials The LK series is available to suit each user's needs in accordance with feeding rate from small to large capacity. Also, material variation has been improved. Selection of the pump material most suitable for the applied liquid is possible with six different types available. High performance and application-oriented versatile design. Discharge accuracy (stability) is within ±2% FS. Reliability is considerably enhanced through efforts to improve the linearity of the stroke / discharge ratio as well as the dispersion between stroke. Two types of joints...

Construction Pump heads Drive from the gear reduction unit is directly transmitted to the diaphragm. This type of metering pump is economical and simple with a high degree of versatility. With the employment of moulded PVC pump-head, and with the new standardization of two types of connections using flanges or hose joints (LK-F11 to LK-F47), not only a saving in parts cost but also improved flexibility of installation has been realized. The three main pump head materials are PVC, stainless steel, or fluororesin. The most suitable type for the application can be selected from a total of six...

Dimensions in mm Points to be observed in pump installation and piping Iwaki metering pump LK series are reciprocating pumps employing the eccentric cam system. Reciprocating pumps generate pulsation in the suction and discharge piping. Special consideration, (different from the ordinary centrifugal pumps), should be given to this point when planning the pump installation and piping. • Prevention of pipe vibration • Prevention of overfeeding Discharge side inertial resistance Pid < 0.1MPa Pump differential pressure > Inertial resistance Pi • Pid : Inertial resistance on discharge side • The...
