About GREENLINE

GREENLINE is a manufacturer of diaphragm metering pumps used for precise chemical injection in industrial processes. The product line supplied by 3G Electric consists of heavy-duty motor-driven diaphragm metering pumps designed for continuous duty and accurate dosing of liquids across a range of viscosities and chemical compatibilities. These pumps are typically specified where repeatable flow rates and resistance to aggressive fluids are required, such as in water treatment, chemical processing, and industrial cleaning systems.

The GREENLINE pumps available through 3G Electric share a common architecture: a motor-driven diaphragm mechanism with a PVDF (polyvinylidene fluoride) pump head, PTFE (polytetrafluoroethylene) diaphragm and seals, and check balls available in either 316 stainless steel or ceramic. The motor is rated for 115/230V AC operation and is available in 1/2 hp or 1 hp configurations depending on the model. Reproducibility is stated as ±2.0% across the range, which supports consistent dosing in applications where over- or under-feeding can affect process quality or safety. Fitting materials include 316 stainless steel or PVDF, allowing selection based on the chemical being metered. The pumps are described as heavy-duty, indicating construction intended for industrial environments rather than light-duty or intermittent service.

3G Electric supplies these GREENLINE diaphragm metering pumps as part of its broader catalog of industrial equipment. The company is headquartered in Singapore and serves customers globally, providing access to multiple SKUs within the GREENLINE line. For technical buyers, 3G Electric offers logistics support and the ability to compare specifications across models to match pump configuration to the application. This includes selecting the appropriate motor horsepower, head and seal materials, and check ball material based on the chemical compatibility and flow requirements of the process. The pumps are available with different MPNs, such as DM1AVAC, DM4C1AG, DM4CVFG, DM6C1AH, DM6C1FH, DM4C1FG, DM6CVFH, and DM4CVAG, each corresponding to a specific combination of motor size, head material, and fitting material.

In application, GREENLINE metering pumps are used for injecting chemicals into water and wastewater streams, dosing acids or bases in pH control, adding biocides or corrosion inhibitors in cooling systems, and metering precise amounts of additives in manufacturing processes. The PVDF head and PTFE diaphragm and seals provide resistance to many corrosive chemicals, while the choice of ceramic or 316 SS check balls allows further tailoring to the fluid. The ±2.0% reproducibility supports processes that require consistent dosing over time. Because the pumps are motor-driven, they are suited to applications where a constant, adjustable flow is needed rather than pulsed injection. The 115/230V AC motor allows operation from common industrial power supplies.

3G Electric's role is to make these GREENLINE pumps available to plant engineers, maintenance managers, and procurement specialists who need to specify or replace metering pumps. The company provides product data, SKU-level detail, and logistics coordination for global delivery. Technical buyers can review the specifications for each model, including motor horsepower, head material, diaphragm and seal material, check ball material, fitting material, and reproducibility, to ensure the pump meets the requirements of their specific chemical dosing application. With multiple SKUs in the GREENLINE line, 3G Electric supports selection across a range of configurations without requiring buyers to contact multiple suppliers.

Common Applications

Frequently asked questions

Common questions about GREENLINE from 3G Electric.

What materials are used in GREENLINE diaphragm metering pump heads and diaphragms?

GREENLINE heavy-duty motor-driven diaphragm metering pumps supplied by 3G Electric feature a PVDF (polyvinylidene fluoride) pump head and a PTFE (polytetrafluoroethylene) diaphragm. Seals are also PTFE. These materials are selected for chemical resistance across a range of aggressive fluids. Check balls are available in either 316 stainless steel or ceramic, and fittings are available in 316 SS or PVDF depending on the model. This combination allows the pump to be configured for compatibility with the specific chemical being metered. The PVDF head and PTFE diaphragm are common in industrial dosing applications where resistance to acids, bases, and solvents is required.

What is the reproducibility of GREENLINE metering pumps?

The GREENLINE heavy-duty motor-driven diaphragm metering pumps listed by 3G Electric have a stated reproducibility of ±2.0%. This means that under consistent operating conditions, the pump is designed to deliver a flow rate within 2% of the set point. This level of repeatability is relevant for chemical dosing applications where precise volumetric control is needed, such as pH adjustment, disinfection, or additive injection. The reproducibility figure applies across the models, including those with 1/2 hp and 1 hp motors. It is a specification that technical buyers can use when comparing pumps for processes that require consistent chemical feed rates.

What motor sizes and voltages are available for GREENLINE diaphragm metering pumps?

GREENLINE heavy-duty motor-driven diaphragm metering pumps from 3G Electric are available with either a 1/2 hp or 1 hp electric motor. The nameplate voltage is 115/230V AC, allowing operation from common single-phase power supplies. The motor is directly coupled to the diaphragm mechanism to drive the pumping action. The choice between 1/2 hp and 1 hp depends on the required flow rate and discharge pressure for the application. Models with 1 hp include DM4C1AG, DM4CVFG, DM6C1AH, DM6C1FH, DM4C1FG, DM6CVFH, and DM4CVAG. The 1/2 hp model is represented by DM1AVAC. Buyers should verify that the available power supply matches the motor nameplate before installation.

What are the differences between GREENLINE models like DM4C1AG and DM6C1AH?

The GREENLINE model numbers indicate specific configurations. For example, DM4C1AG and DM6C1AH both have a 1 hp motor, PVDF head, PTFE diaphragm and seals, and ±2.0% reproducibility. The differences lie in the check ball and fitting materials: DM4C1AG uses 316 SS check balls and fittings, while DM6C1AH also uses 316 SS check balls and fittings but may differ in other internal details. Other models such as DM4CVFG and DM6C1FH use ceramic check balls and PVDF fittings. These variations allow selection based on chemical compatibility and wear resistance. Technical buyers should review the individual SKU specifications to match the pump to the fluid being metered.

Can GREENLINE metering pumps be used for aggressive chemicals?

GREENLINE heavy-duty motor-driven diaphragm metering pumps are constructed with materials intended for chemical resistance. The PVDF head and PTFE diaphragm and seals are resistant to many acids, bases, and solvents. The check balls are available in ceramic or 316 stainless steel, and fittings in 316 SS or PVDF, providing options for different chemical compatibilities. However, the suitability for a specific chemical depends on concentration, temperature, and other factors. Technical buyers should consult chemical compatibility charts and the pump specifications to confirm that the wetted materials are appropriate for the intended fluid. 3G Electric supplies these pumps but does not provide chemical compatibility guarantees; verification is the responsibility of the user.

How does 3G Electric support GREENLINE diaphragm metering pump selection?

3G Electric provides access to multiple GREENLINE diaphragm metering pump SKUs and supplies product data including motor horsepower, head material, diaphragm and seal material, check ball material, fitting material, and reproducibility. This allows plant engineers and procurement specialists to compare configurations and select the model that matches their flow, pressure, and chemical compatibility requirements. 3G Electric also offers logistics support for global delivery. The company does not manufacture the pumps but distributes them as part of its industrial equipment catalog. For technical assistance beyond the published specifications, buyers should refer to the manufacturer's documentation or consult with a qualified engineer.
