Detailed Description
The EK series pumps are the world's first IP67 electronic metering pumps. This means that the EK is the only pump in the industry guaranteed to operate submerged 3 feet under water. Needless to say, the EK series pumps are ideal for wet or high humidity environments such as irrigation, agriculture, car wash or paper mill applications. Capacity ratings are up to 6.7 GPH with a maximum pressure of 150 PSI. The rugged polyphenylene oxide enclosure is equipped with a durable clear cover to protect the membrane switches and stroke control of the pump, which are mounted opposite the liquid end. A variety of liquid end combinations are available to ensure a perfect match for your specific application.

IP67 Construction
By integrating the pump body into a one-piece design, sealing is easier and more effective. Both the drive and the controller are completely insulated from moisture or gas. A watertight clear cover protects the display, controls and stroke length adjustment. All circuit boards and electronic components have been completely encapsulated to prevent failure due to moisture or gas. The display utilizes a high temperature LCD that provides extra protection from long-term exposure to sunlight in outdoor applications. Construction of the EK Series pumps make them perfect for indoor or outdoor applications where the pumps are frequently exposed to wash down.

Control Features
High speed and a 20% minimum stroke length allow the EK series to achieve an 1800:1 turndown ratio. The digital display and pushbutton speed control make setting the EK pump easy and precise. The EK pumps come equipped with pulse input (1:1) control and also feature and external stop input that can be set to stop the pump from a normally open or normally closed contact. To maintain the IP67 rating a proprietary connector is utilized that makes connection of the inputs simple, yet retains a watertight seal.

Control Features
All EW series pumps come equipped with pulse, stop & pre-stop inputs in addition to stop & pulse output control. The EW-Y module also features:

Feed Accuracy
Powered by the E-class 360 Stroke-Per-Minute technology, the EW has an incredible adjustment range of 1800:1 ensuring precise feed control for any application.

Analog Input Control
Fixed or scalable 4-20mA input control.

Pulse Input Control
Pulse input with multiply and divide features(1-9999). 12VDC output power supply for Hall Effect water meters.

Quick-Prime
Hold 2 keys down and pump runs at 100% of speed to prime quickly without adjusting application settings.

Feed Verification
The EW is equipped with three pre-programmed modes for accepting the Posiflow Feed Verification Sensor. The Posiflow provides a pulse feedback to the pump to verify prime and proper feed. Depending on the mode, the user can program the pump to stop, continue operating and/or send an alarm based on the Posiflow input.

Easy Draw-Down Calibration
In the calibration mode the user needs to start and stop the pump, enter the draw-down volume and the pump calibrates volume-per-stroke.

Flow Rate Display
After calibration, the EW will display the flow rate. As long as stroke length is constant the pump will accurately display the volume of fluid being pumped. In cases where the pump is being controlled externally with a pulse, the pump will display and count down remaining flow based on the pulse input. Couple with the Posiflow Feed Verification, the EW ensures proper feed for your application.
