The Iwaki LK series pumps are motor driven mechanical diaphragm metering pumps designed for accurate and easily controlled chemical dosing. The LK range offers one of the widest capacity ranges available. Robust construction, long service life and compact size are features of this range. Manual stroke length control is standard, with optional electric stroke positioners available. Automatic flow control via 4-20mA or pulse signals is possible.
Wetted materials including PVC, ceramic, PTFE,316 s/steel, Hastelloy C and PVdF are available to handle nearly all industrial chemicals.
Relief valves, loading valves, pulsation dampeners, calibration cylinders, servo stroke actuators and automatic controllers are available.
19 models covering maximum capacities from 1.2 to 3240 litres/hour. Discharge pressures up to 15 bar. Manual or electric stroke length control range of 5:1 is available. Automatic speed control range up to 120:1 is possible with the MFC controller.
Standard IEC B5 flanged industrial motors are used without the need for special adaptors, allowing easy fitment of Ex’d’ or other hazardous rated motors when required.
MFC Controller for Iwaki Motorised Metering Pumps
Allows automatic control of pump stroke rate from 0 to 120 spm.
Combination of stroke length adjustment with stroke rate enables capacity control over a 1:480 range.
Can be locally mounted with pump or remotely in MCR.
Analogue 4~20mA input and pulse input with divide/multiply operation.
Capacity display in litres/hr or SPM is user-selectable.
Large LCD display and touch keys offer user-friendly operation.
Key lock, fast priming, no flow-detection & external level sensor control are incorporated to assist chemical dosing management.
