The EJ Series provide precise chemical injection at an economical price. Universal voltage capability enables operation from 100 – 240VAC in virtually all countries. The EJ Series are compact, simple to operate and have outputs to 3.2 GPH (12.0 LPH) and a maximum pressure of 175 PSI (1.2 MPa).

Key Benefits:

High Speed Performance
The EJ Series operate at 360 strokes-per-minute, providing high resolution chemical feed and high turndown capability. Most competitive products operate at slower speeds, resulting in slug feeding, accelerated diaphragm wear and poor feed control.
Universal Voltage
The Universal Voltage Function enables the EJ Series to operate at any AC voltage. The EJ Series also conform to global Standards.
External Control
The EJ Series have both digital input and Stop/Start inputs built into the pump, enabling either proportional or On/Off control.
IP65 Equivalent Protection
A robust housing protects the pump from normal wear. Mounting the Digital Display and Key Pad control within the drive housing creates a highly water resistant design. A clear cover further protects the pump from liquids.

Pump

Specifications based on water at rated voltage and ambient temperature.

Flow rates were collected at the maximum discharge pressure and
360spm. Degassing option derates capacity by approximately 20%.
*B09 size is available in PVC liquid ends only
Flow rate increases as discharge pressure decreases.
Allowable ambient temperature: 0 to 104°F (0 to 40°C)
Allowable liquid temperature: 0 to 104°F (0 to 40°C)
Allowable power voltage deviation: ±10% of the rated voltage
Noise level: 65dB at 10 ft. (A scale)
E90495 (field-wireable connector) or IX0018 (connector with 5m cable)
required for Inputs. (not-included)
All pumps include a manual air vent valve except FC/SHN models.
All pumps include one foot valve, injection valve, 20 ft. of PE tubing
and ceramic weight except for SHN models.

Controller

The max voltage from the EJ to an external contact is 15V at 3mA. When
using a mechanical relay, the minimum load should be 3mA or below.
When the external pulse signal is over the max spm, the extra pulses are
ignored.
The allowable voltage range is 90 to 264VAC. Outside of this range, failure
may result.
