Diaphragm pump technology has been in use for decades and these pumps remain a popular choice for chemical dosing in both public and industrial wastewater treatment. The technology is affordable and familiar, providing a high degree of operator comfort.
Despite these advantages, traditional diaphragm pumps can be problematic. Operators often struggle with inconsistent performance issues such as pulsation, unexpected flow rate variation, vapor locking, diaphragm wear, leaks and overall high maintenance. The good news is that recent innovations in diaphragm pump design eliminate these issues.
Dual-Diaphragm Hyper-Drive Technology
Recent technological advancements have resulted in high-performance smart pumps that are essentially plug-and-play. The core innovation is dual-diaphragm Hyper-Drive technology. This technology operates one diaphragm in the suction phase of the pumping action, and the other diaphragm is in the discharge phase, resulting in smooth, consistent dosing regardless of motor speed. The pump delivers near-continuous chemical dosing, preventing chemical agitation and it effectively mitigates issues with vapor lock.
Blue-White Hyper-Drive technology — which is incorporated in the company’s Enhanced Performance CHEM-FEED MD1 Diaphragm Metering Pump — also features a brushless direct current (BLDC) motor for continuous, noninterruptive rotation, ensuring smooth, steady flow of fluid for consistent chemical delivery throughout the entire dosing cycle. The BLDC motor also reduces energy consumption and provides long-lasting durability in harsh environments.
Material and Design Enhancements
MD1 incorporates additional design innovations to reduce maintenance, increase the pump’s lifespan, and reduce downtime and operator frustration. These include:
DiaFlex Diaphragm. Manufactured in-house from patented material, DiaFlex Diaphragms have the rigidity necessary to withstand a wide range of abrasive chemicals, as well as the flexibility required to operate as a diaphragm. DiaFlex has been rigorously tested and is warranted to last the life of the pump, reducing both downtime and expense.
One-way cartridge valves. The MD1 is equipped with mistakeproof one-way check valves that are engineered so the user can only install the valves in the correct direction. This prevents the potentially dangerous issues, including leaks or pipe ruptures.
Reengineered pump head mount. The pump head mount has been slightly enlarged and reinforced to minimize flexing relative to the drive enclosure. This allows for even more consistent flow rates and performance.
Upgraded center bearing. A significantly larger center bearing provides better support for the motor driveshaft, reducing lateral movement and increasing overall durability. This increases the durability of the pump and minimizes shaft deflection and wear.
Performance and efficiency. The MD1 delivers up to 7.0 gph at 180 psi. This level of performance covers demanding municipal and industrial applications.
Simple connections. I/O connections are made easy with M12 connectors, which means no more complex wiring. A USB-C connector allows for easy firmware updates in the field.
The system features an output range of 0.0007 to 7 gph, a suction lift of 20 feet, and operates at pressures up to 180 psi (12.4 bar). It is powered by a brushless DC motor and offers a turndown ratio of 10,000:1. The unit includes a five-year warranty and meets NEMA 4X (IP66), NSF/ANSI 61, CE and cETLus standards.
