Description
The A4 (Legacy) FLEXFLO Peristaltic Metering Pump is a positive displacement chemical metering pump that delivers smooth, continuous chemical feed. It is especially effective when injecting chemicals that off-gas like Peracetic Acid and Sodium Hypochlorite. The peristaltic technology is a near-continuous flow that delivers consistent precise flow without the need for check valves.
Note: The A4 (Legacy) pump has a newer version. If you have questions about the new A4S FLEXFLO pump, click here.
The A4 (Legacy) Legacy pump has two versions. The A4V pump has remote speed control via 4-20ma, 0-10 VDC, Frequency, and Pulse inputs. The A4F pump has only manual speed adjustment.

Applications
The A4 (Legacy) pump is designed to provide smooth chemical feed for a variety of chemicals and processes. It can reliably pump chemicals that off-gas such as sodium hypochlorite, peroxide, ammonia, and PAA (peracetic acid), as well as a variety of other chemicals.
The A4 is effective with suction lifts, polymers, slurries, and solutions with minor debris that would normally cause issues with diaphragm pumps.
