The hydraulic end of the pump uses a diaphragm to form the working chamber. The diaphragm undergoes periodic elastic deformation to replace the reciprocating motion of a piston, hence the name diaphragm pump. Driven by electromagnetic force, the diaphragm flexes back and forth in a periodic motion — this is known as an electromagnetic diaphragm metering pump.
Reverse osmosis, electrodialysis circulation, cooling water purification, sewage treatment laboratories, testing labs, and other small-flow chemical dosing scenarios.
Metering pumps are widely used in petroleum, chemical, oil refining, power generation, food processing, environmental protection, mining, water treatment, textile, plastic foaming, papermaking, pharmaceutical, defense, and scientific research institutions.

The TE Series Mechanical Diaphragm Metering Pump is primarily used for precise dosing of chemicals in industrial processes, water treatment plants, and in any application where accurate and reliable fluid metering is required. These pumps are designed to handle a wide range of chemicals, including corrosive, viscous, and abrasive fluids, making them suitable for diverse environments.
The TE Series Mechanical Diaphragm Pump ensures accurate chemical dosing through its unique diaphragm design, which provides a fixed volume of fluid with each stroke. This design, combined with adjustable stroke length and rate, allows for precise control over the flow rate and dosage volume. Additionally, the pump's metering accuracy is maintained by its robust mechanical operation and the use of high-quality materials that resist wear and chemical degradation.
Yes, the TE Series pumps are designed to handle hazardous chemicals safely. They feature sealed diaphragms that prevent leaks and spills, and can be constructed with materials that are compatible with aggressive or hazardous chemicals, ensuring that the pumps meet safety and performance standards in critical applications.
Regular maintenance for the TE Series Mechanical Diaphragm Pump includes checking and replacing the diaphragm, as well as inspecting and lubricating the mechanical components. It is also important to clean the pump and its components periodically to prevent buildup of residues, especially when handling viscous or abrasive fluids. Consult the user manual for a detailed maintenance schedule and specific instructions tailored to your pump model.
The key benefits of choosing a TE Series pump include high metering accuracy, excellent chemical resistance, and robust construction. These pumps offer reliable performance even in harsh conditions, have low maintenance requirements, and can operate at varying temperatures and pressures. Their modular design allows for easy customization to meet specific process needs, and their broad range of available options and accessories makes them a versatile choice for various industrial and treatment applications.
