SpecificationsA key differentiator of Iwaki is their large variation of products,often considered the Widest range of specialist Chemical Pump 

ES Series 
Precise chemical injection at low cost 

High speed operation
Up to 360 strokes per minute results in high resolution chemical feed, elimination of slug-feed effects.

Compact size
Ideal for OEM specifications, ES pumps are small, quiet, and lightweight.

Double ball check valves
The ball, seat and guide assembly ensures a tight seal to prevent loss of prime.

Long lasting diaphragm
PTFE laminate over EPDM is molded onto a solid core. A retainer plate is provided to minimize flow rate changes as pressure varies.

Specification

EHN Series 
The latest electromagnetic metering pump equipped with digital controller & multi-voltage

Multi-voltage power source
Multi-voltage power source from AC100 to 240V for all models. You are now free from worrying about power voltage. 

High resolution
Thank to digitized controller, stroke speed can be adjusted by 1 spm step from 1 to 360 spm. Combined with stroke length adjustment, you can do the fine adjustment from very small flow to maximum flow rate.

Pump head variation
Wide variety of standard pump head (VC/VH), automatic bleeding type (NAE) and high compression type (55 model). Note : Refer to page 4 for details of NAE and 55.

Air vent valve
Small flow capacity models (EHN-10, 15 & 20) equip air vent valve. Air in the pump chamber can be easily released by turning knob. 

Water/dust-proof
Each unit such as driving unit and control unit is sealed to make the pump IP66 equivalent water/dust-proof. Note : Do not install pump outdoor.

Specification

LK Series
Applicable to the many diverse needs of chemical feeding

Easy to use, multi-purpose design
This series includes the most economical and general-purpose pumps in our metering pump series. In fact, the first metering pump in Japan to use a PVC-molded pump head belonged to this series. Three types of standardized connections "flanges, hoses, and unions (0.2 kW type only)" as well as a full line of accessories are available. What's more, parts are manufactured at low cost and designed to be easy to use.

Highly durable pump drive unit
The pumps in this series use a worm-gear-type speed reducer which, though compact, is highly rugged and reliable. Since this unit is fully closed, oil-bath lubricating type, it can be installed outdoors. At the same time, it exhibits superior durability over long-term continuous operations.

A wide variety of pump models and material compositions
This series includes nine of exclusive motor types and ten types of general-purpose motor types. This extensive lineup covers a wide range of application needs, involving everything from trace to large amounts of fluid. What's more, the pump head is manufactured using various materials including PVC, fluororesin, and stainless steel, making the pump useful for almost all chemical dosing needs.

MD Series
Highly reliable, compact magnetic drive pumps

Highly reliable, compact magnetic drive pumps. Field-proven reliability
A large number of pumps in this series have been delivered to customers at home and abroad, earning high acclaim for their superior reliability. This is the best-selling series in the world.

An incomparable range of models available
The MD series comes in a total of 38 models. A wide range of flow rates, hose connections, and threaded connections (M type) are available as standardized models. In addition, dedicated high-head, large-flow-rate models are available. The most economical and suitable pump can be selected from this wide variety of models.

Leakage-free, sealless structure
As is common with corrosion-resistant pumps, this series uses the magnetic drive method, eliminating problems caused by liquid leakage.

Superior corrosion resistance
The pumps in this series are constructed mainly with polypropylene while at the same time using superior corrosion-resistant parts manufactured from ceramics, PTFE, and FKM. Therefore, they can be used to transfer strong acids and various other chemicals. 

Simple and compact 
The pump structure is extremely simple. Consisting of several unitized parts, the pump is easy to maintain.

Specification

MX Series
Reliable & energy efficient magnetic drive pumps 

Self-radiating structure (PAT.) 
Through heat-dispersion holes provided in the fixed portions of the impeller and the magnet capsule, the liquid around the spindle and the bearing is forced to circulate so that heat generated by sliding can be reduced effectively. Thus, thermal deformation and melt are prevented.

Non-contact structure
By installing the driving magnet and the driven magnet in an inventive way, the movement of the magnet capsule is controlled by magnetic force to prevent the rear thrust and the rear portion of the bearing coming into contact with each other continuously even during dry running. This structure reduces heat generation and secures lubricant routes. (Except MX-70, 100)

Volute casing divided into two sections (PAT.)
The MX series is the first resin magnet pump which uses the pump casing divided into the front casing and the rear casing to form a vortex chamber as an ideal form. Therefore, the internal leak phenomenon, which means that the liquid getting out of the impeller returns to the pump casing and is suppressed to a minimum and the liquid is efficiently guided to the discharge port to enhance overall efficiency. 

Robust structure
All stress bearing portions, such as the front and rear casings, are reinforced by means of ribs to improve the pressure resistance and the mechanical strength of the pump. The bearing is not only fixed by conventional press fit but is also sandwiched between the abutting portion in the depth of the magnet capsule and the rear end of the impeller to improve its reliability under high temperature. (Except MX-70, 100)
