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.

The IX series are digitally controlled stepper motor-driven metering pumps which span the application range between small solenoid & conventional motorised metering pumps. Their electronically controlled direct-drive stepper motor provides an extremely wide capacity range. Up to 750:1 capacity turndown is possible while retaining ±1% accuracy and virtually constant chemical injection, even at low flows.a smooth flow characteristic.

Materials
Wetted materials are PTFE, PVdF with ceramic or 316 s/steel to handle virtually all common water treatment chemicals.

Control Modes
The IX can operate in various automatic modes including external proportional pulse, analague 4-20mA, preset batch or interval batch. Flow detection and failure alarm, flow readout in either litres/hr or strokes/min. This model also features a motor overload and diaphragm rupture sensor with two relay outputs, selectable from a preset menu, allowing the operator to customize alarm output signals. The IX also features data logging capabilities including operating time, total flow volume, power on time and number of On/Off’s. Suction stroke speeds are adjustable through 4 speeds (100%, 75%, 50% and 25%) for cavitation prevention when pumping viscous liquids.

Capacities
Three sizes cover from 0.08 to 300l/hr at discharge pressures up to 10 bar.

Flexible Installation
The controller with backlit LCD display can be mounted in several different positions according to operator preference. Screwed connections are standard, with ANSI flanges also available.

The Iwaki EWN-series pumps are electronically controlled solenoid driven metering units capable of highly accurate and easily controlled chemical dosing. Manual, semi-automatic or fully automatic control is possible by combining suitable inbuilt control modules.

Additional safety accessories are available for extra security when used in the most critical applications.

Materials
Wetted materials including PVC, ceramic, PTFE, 316 s/steel, Hastelloy C, GFRPP and PVdF are available to handle nearly all chemical solutions. Tubing connections are used for fast and easy installation.

Control Modes EWN-R / EWN-Y EH-E Series
The standard EWN-R model now combines complete functionality for either manual or automatic operation in a single range: Manual capacity control with either auto stop or external pulse, or; Programmable automatic control from either 4-20mA, preset counter or proportional pulse. Pulse divide/multiply functions with alarm output (EH-E only), flow detection and failure alarm, flow readout in either litres/hr or strokes/min.

Capacities
10 12 models cover maximum capacities from 0.7 2.28 to 75.0 litres/hour & discharge pressures up to 10 bar. Turndown range of 720:1 up to 9001800:1 (depending on model) is available using a combination of manual stroke length and automatic stroke frequency control.

Additional variants for specific requirements
EWN-A type – with high compression / automatic degassing pump head for gassing chemicals such as sodium hypochlorite.

EWN-Y type – includes all the features of the standard EWN-R, plus the capability of self-calibrating, real-time flow readout when used with the EFS flow sensor incorporating feedback control. Simple flow monitoring functions can be achieved using the optional FCM or FCP flow checkers to detect abnormal flow conditions. Alarm and analogue output functions as standard provide additional options for flow verification.

The EWN-A auto degassing valve can be combined with the EWN-Y with EFS for a completely self-calibrating, self-degassing solution with automatic fast-prime capability
