The Iwaki LK Series metering pumps are motor-driven, mechanically-actuated diaphragm metering pumps.

In a class by itself - the LK is a motor driven, mechanically actuated diaphragm metering pump with a maximum capacity of 114 GPH (432 l/h) and maximum pressure of 225 PSI (1.5 MPa).

The LK Series metering pump is the largest in the high performance line of pumps from Walchem. The LK is a motor-driven, mechanically actuated diaphragm metering pump with a maximum capacity of 114 GPH (432 l/h) and a maximum pressure of 225 PSI (1.5 MPa). 

The heart of the LK is a compact and very reliable dual-cam system drive and worm gear reducer. Roller bearings and oil bath lubrication ensure out- standing durability and wear resistance in continuous operation.
