A new peristaltic metering pump designed for use in smaller municipal water and wastewater treatment systems will be on display at ACE13. The pump includes many of the features and options seen in far more expensive pump models, which are primarily designed for large municipalities.

The Proseries-M™ M-2 pump from Blue-White is well-suited for injecting anionic and cationic polymers. The gentle squeezing action of the valve-less pump head design results in a near continuous injection of the chemical, ensuring a reliable stream of undamaged polymer for efficient wastewater treatment applications.

The Proseries-M™ M-2 pump from Blue-White is designed for use in smaller drinking water and wastewater systems.

This new pump is also a choice for pumping chemicals that can vapor lock a pump, such as sodium hypochlorite and hydrogen peroxide. The Proseries-M permits standardization to a single pump model for many different applications since it can handle a wide variety of aggressive and viscous chemicals, including 98 percent sulfuric acid, ferric chloride, fluoride, anionic and cationic polymers, sodium hydroxide, carbon slurry, and aluminum sulfate. The operator simply changes the pump tube assembly to the appropriate material for the chemical being injected.

The M-2 can inject into a wide variety of system pressures, from a full vacuum to 125 psi positive head pressure. The only regularly-required maintenance is periodic changing of the pump tube assembly.

The new pump features Blue-White's patented Tube Failure Detection system. Sensors constructed of chemical-resistant Hastelloy-C are located within the pump head. If a chemical is detected in the pump head (by tube failure), the pump will automatically shut off and energize a relay, permitting communications with external equipment, such as an alarm or a SCADA system. The chemical must be cleaned from the pump head and the tubing should be replaced before the pump will start again. Only Blue-White Industries offers this technology.

Standard control features for the M-2 include an intelligent control systems design that permits connection to SCADA systems and other remote controllers for chemical dosing control via either a 4-20 mA signal, a high speed digital pulse input or a slow pulse for batching type applications.

Optional advanced SCADA communications command and status capabilities include start, stop, prime, and set point speed, touchpad locking and unlocking, motor status, pump head cover status, tube failure detection status, alarm reset, running hours reset, and many others. Available communications protocols for the M-2 include Profibus DPV1, Modbus RTU, Modbus-TCP, EtherNet/IP, and Profinet RT I/O.

The quiet, smooth, low-velocity injection system eliminates the destructive forces that solenoid-type diaphragm pumps can have on piping systems. This eliminates the need for pulsation dampeners and expensive piping system repairs.

The pump is Flow Verification Sensor (FVS) ready. The firmware is field upgradable, so the plant can always stay up-to-date with the latest software. The digital motor controller and high-torque DC motor is internal to the NEMA 4X enclosure, making the pump easily movable to a convenient dosing location.

Additional pump specifications include feed rates from .01 to 15 gph, pressures to 125 psi, 200:1 turndown ratio, variable speed DC motor, and a self-priming, valve-less design that cannot vapor-lock.
