• Interfaces easily with a variety of process controllers
• 4-20 mA input can match changes in process conditions

Pulsafeeder's Series E Plus pumps are best used for fluoridation systems requiring precise chemical feed rates. The wet end materials provide exceptional chemical compatibility in fluoride applications. These pumps accept a direct 4-20 mA signal to control the frequency (strokes per minute) of the pump. Pump output can be adjusted manually or remotely through the use of a SCADA or PLC system.

Stop function port allows you to automatically shut off the pump when your chemical day tank is empty or when there is no flow in the process stream. These pumps also feature a convenient on/off/automatic switch. Totally sealed housing protects the electronics and is durable enough to ensure years of precise, repeatable performance.

Includes: injection check valve assembly, foot valve/strainer, suction valve, discharge valve, 4' PVC suction tubing and 8' polyethylene discharge tubing. Pumps also include 2 signal cords: 1 stop function signal cord and 1 signal cord for either external pacing or 4-20 mA signal input. Repair kits include: pump head, replacement diaphragm, seal, 4 pump head screws and check valves.
