Introducing Iwaki's EWN Metering Pumps

Chemical feed, as vital components in the treatment of water, metering pumps satisfying a diverse range of applications. Iwaki’s mission is to provide solutions for any application safety, accuracy fast and flexible support for the constantly evolving marketplace. Iwaki’s metering pumps are integral to the worldwide dosing pump market. As part of an extensive product offering their electromagnetic metering pumps are synonymous with quality and performance, resulting in a record of high reliability.

Only from Iwaki is true high-speed chemical feed a reality. 360 stroke per minute operation coupled with variable stroke length control allows the EWN the most precise control and adjustability available.

The enclosure of the EWN series has been designed with consideration of the water and dustproof specifications of the ip65 standard. A sealable cover over the controller further allows the pump to be used in many diverse environments. The electromagnetic drive unit of the EWN 30 series is much smaller than mechanical drives and offers much more control adjustment. Two types of drive units are available the B type and the C time providing for unique output requirements.

The EWN series launches Iwaki’s new universal connection system. A new coupling nut design allows for any size connection available while preventing the twisting of tubing during connection. There are four standard liquid end materials available within the product series PVC, GFRPP, PVDF, and 316 stainless steel. These core materials allow the best combination of materials for any application at the most economical rate. In addition to the standard pump line the EWN series includes specific models targeted to unique applications. The high compression pumps were designed for chemicals that out gas such as sodium hypochloride.

Increasing volume per stroke and decreasing dead volume increases the compression ratio making a pump design excellent for pumping chemicals that contain a lot of gas. The high-pressure pumps were designed for feeding chemicals into applications at higher pressures than the standard pumps. The high viscosity pumps were designed to efficiently pump viscous materials such as polymers and other coagulants. The pump controller utilizes several control methods for output control. Manual control is achieved through stroke length adjustment or pump speed adjustment or a combination of both.

Stroke rate is displayed as a percentage of full speed or one of several flow rate units. in addition to manual control the pump is also capable of being proportionally controlled by either analog or digital input signals. The multiply control can be used to set multiple pump strokes for every digital input. The divide control allows the pump to stroke for a predefined number of input signals.

Programmable analog control allows control of a pump stroke range between any two arbitrary points of the 0 to 20 milliampere scale. To support the full line of metering pumps. A complete range of accessories is also available from Iwaki accessories can be configured for any application providing a unique pumping solution for the customer.

Iwaki metering pumps play an important role across the globe building on their successes, experiences, and long pump history. Iwaki strives to continue to provide products and solutions for the water treatment market through continuous improvement.

Now and in the future you can rely on Iwaki for your metering pump needs.
