Water and wastewater treatment plants continue to evolve, with constant efforts to make the treatment process more automated. Blue-White is at the forefront of these innovative solutions, as the company has simplified chemical feed by offering a 4-20 mA signal out from their popular CHEM-FEED MD1 Multi-Diaphragm Metering Pump and FLEXFLO M1 Peristaltic Metering Pump.
The 4-20mA signal can be sent from the pump to a SCADA system where operators can remotely monitor the pump, allowing for improved automation and monitoring. The mA signal can also be used as an input for another device for controlling multiple devices with a single mA signal.
“The benefit is that you can now provide a remote feedback signal to tell you how the pump is operating remotely,” says Patrick Murphy, Blue-White’s vice president of operations. “It also can be tied to another device for control purposes. For example, a 4-20mA output signal from one pump can be sent to another pump’s 4-20mA input signal. The pump receiving the input signal is now being controlled by the pump sending the output signal.”
The FLEXFLO M1 Peristaltic Dosing Pump will not vapor lock and never loses prime. This self-priming chemical feed pump delivers smooth, consistent, and precise chemical dosing. The CHEM-FEED MD1 has dual-diaphragm hyperdrive technology, which provides a continuous chemical feed that is engineered for zero maintenance. The DiaFlex diaphragm is built to last the life of the pump.
“Along with the 4-20mA upgrade, our pumps now come with chemical-resistant metal M12 connectors that are IP67-rated,” says Murphy. “The connectors are made from high-quality materials and are designed to withstand harsh environments. They are resistant to shock, vibration, moisture and extreme temperatures.”
According to Murphy, the initial upgrade research started with customer visitations. “We heard customers loving the pump, but wish they could see what it was doing remotely without any additional devices,” he says. “We also heard that they wanted a way they could send a signal from the pump to another pump rather than sending running run wires to multiple pumps for a 4-20mA signal.”
And according to initial user feedback, they love the upgrade. “Not only are they able to have more capabilities with automation, they love the durability of the chemically resistant metal connectors,” says Murphy. 714-893-8529; www.blue-white.com
