Grundfos offers a wide range of dosing pumps representing state-of-the-art technology. Grundfos Digital Dosing solutions (SMART Digital, DME, DDI) set new standards in liquid chemical handling and accuracy. The operator can easily install and set up the pump to discharge exactly the quantity of dosing liquid required for the process in a unique drive- and flow-control management concept. The setting of the pump is displayed in ml/h, or l/h and the operation mode is easily identified by means of icons. The dosing pumps are designed for handling chemicals within the following applications:
Features and benefits
The Iwaki ES series pumps are cost-effective electronically controlled solenoid driven metering pumps designed for basic dosing requirements. They are suited to applciations requiring manually controlled highly accurate chemical dosing and are ideal for OEM applications.
Control Modes: ES Series
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.
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.
Additional variants for specific requirements include:
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.
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
The Mono range of dosing pumps offers an efficient, reliable and low maintenance solution for applications where low flow, accurate dosing is required. The Mono dosing pump provides a smooth pumping action with no pulsation and very low shear. The pump is ideal for either intermittent or continuous dosing duties in high pressure, low flow applications, and represents a cost-effective and reliable alternative to the more expensive gear pumps traditionally used for these types of duties. The modular design of the new dosing pump allows the four models in the range to cover performance requirements from 25 litres per hour up to 1,250 litres per hour and 72 bar pressure.
