A2

FLEXFLO® Peristaltic Metering Pump

Simplify chemical feed with the FLEXFLO® A2 Peristaltic Metering Pump. This rugged and compact pump features a gentle, low-shear pumping action, making it an ideal choice for dosing shear-sensitive or gaseous fluids. The A2 does not require check valves, seals, or other ancillary equipment to function, reducing maintenance intervals and process downtime.

Remote control signal options include Remote Start/Stop, Flow Verification, Pulse, and 4-20mA.

Features

Benefits:

• Self-priming – even against maximum line pressure. By-pass valves are not required. Cannot vapor lock or lose prime. 30ft of suction lift. Gentle low shear pumping action.
• Tube Failure Detection (TFD) senses tube rupture by detecting chemical in the pump head. No false triggering – Patented
• Optional dual channel tube design for optimum performance and pressure capability

Communication and Interface:

• Operator friendly digital controls with backlit LCD displays motor speed, input signal values, service, and alarm status
• Inputs include: 4-20mA and pulse inputs for remote external speed control and either powered 6-24 VDC or non-powered dry contact closure for remote start/stop
• Outputs: one 250V/3A relay to monitor TFD (Tube Failure System) and FVS (Flow Verification System), one 4-20mA analog signal scalable to the motor speed and one relay output for run status
• Compatible with Blue-White’s output Flow Verification Sensor (FVS) system. Sensor is sold separately

Superior Design:

• 2 Year Warranty
• 100:1 turndown ratio
• NEMA 4X (IP66) wash-down, chemically resistant powder coated enclosure
• Heavy duty rotor means no flexing and increased accuracy with no metal springs or hinges to corrode.

Safety Features:

• Tube Failure Detection (TFD) senses tube rupture, preventing hazardous chemical spills

Optional Components Available:

• Mounting Extended Brackets (72000-380) – 1 Pair, SS, 4 SS Screws
