NEXTSTEP

NEXTSTEP is a brand specializing in high-precision stepper motor-driven diaphragm metering pumps designed for chemical dosing applications. The product line focuses on electrically actuated metering pumps that use a stepper motor to drive a diaphragm, enabling accurate and repeatable fluid delivery. These pumps are constructed with a PVDF (polyvinylidene fluoride) head and a PTFE (polytetrafluoroethylene) diaphragm, materials selected for chemical resistance and durability in aggressive environments. Internal components include ceramic internals, which provide wear resistance and dimensional stability under continuous operation. The pumps feature a 3333:1 turndown ratio, allowing precise flow control across a wide range of setpoints. Accuracy is rated at ±1.0% of the setpoint, suitable for processes requiring consistent dosing. The pumps operate on 115/230V AC power, making them compatible with standard industrial electrical supplies. Seal options include FKM (fluoroelastomer) for compatibility with various chemicals. NEXTSTEP pumps are applicable in water treatment, chemical processing, and industrial fluid handling where precise metering of liquids is required. 3G Electric supplies multiple SKUs of NEXTSTEP metering pumps, each with detailed datasheets covering specifications such as flow rate, pressure ratings, and material compatibility. The product range includes models with varying flow capacities, identified by MPN prefixes such as NS1, NS3, NS4, NS5, and NS9, which correspond to different pump sizes and performance characteristics. 3G Electric provides logistics support for global shipment, ensuring that procurement specialists and plant engineers can source these pumps for projects worldwide. The pumps are designed for panel or wall mounting and include standard electrical connections for integration into control systems. The stepper motor drive allows for digital control inputs, enabling remote adjustment and automation. The diaphragm design eliminates the need for packing seals, reducing maintenance requirements. The PVDF head and PTFE diaphragm provide resistance to a broad range of acids, bases, and solvents. The ceramic internals contribute to long service life in abrasive or corrosive media. The 3333:1 turndown ratio allows the pump to operate effectively from low to high flow rates without sacrificing accuracy. The ±1.0% accuracy specification is maintained across the operating range, making these pumps suitable for applications where dosing consistency is critical. 3G Electric's catalog includes these pumps with clear specifications, allowing engineers to select the appropriate model based on flow requirements and chemical compatibility. The pumps are available with FKM seals for applications requiring enhanced chemical resistance. The product line does not include integrated controllers or flow meters; these are separate components that can be added to the system as needed. The pumps are designed for continuous duty and can be used in batch or continuous processes. The stepper motor provides precise control over stroke length and frequency, enabling fine adjustment of flow rate. The pumps are self-priming and can handle liquids with viscosities up to a certain range, though specific limits should be verified from the datasheet. The pumps are not rated for explosive environments unless explicitly stated. The construction materials are selected for compatibility with a wide range of chemicals, but users should verify compatibility with their specific process fluid. The pumps are supplied with standard NPT or BSP connections, depending on the model. The electrical enclosure is rated for indoor use; outdoor installation may require additional protection. The pumps are designed for easy installation and maintenance, with replaceable diaphragm and valve assemblies. The stepper motor drive eliminates the need for variable frequency drives or mechanical stroke adjusters, simplifying control. The pumps can be integrated with PLCs or other control systems using standard analog or digital signals. The product range covers flow rates from approximately 0.5 to 20 gallons per hour, depending on the model, with discharge pressures up to 150 psi. These specifications are typical for the series and should be confirmed from the specific datasheet. 3G Electric provides these pumps as part of its industrial equipment portfolio, supporting global customers with technical documentation and logistics.

Frequently asked questions

Common questions about NEXTSTEP from 3G Electric.

What is the accuracy specification of NEXTSTEP metering pumps?

NEXTSTEP metering pumps are rated for ±1.0% accuracy of the setpoint. This specification applies across the pump's operating range, which includes a 3333:1 turndown ratio. The accuracy is maintained through the stepper motor drive, which precisely controls diaphragm displacement. This level of accuracy is suitable for chemical dosing applications where consistent flow is required, such as water treatment or chemical processing.

What materials are used in the wetted parts of NEXTSTEP pumps?

The wetted parts of NEXTSTEP pumps include a PVDF head, PTFE diaphragm, and ceramic internals. PVDF provides chemical resistance to many acids, bases, and solvents. PTFE offers low friction and high chemical inertness. Ceramic components are used for check valves and other internal parts, providing wear resistance. Seal options include FKM (fluoroelastomer) for enhanced chemical compatibility. These materials are selected for durability in corrosive environments.

What power supply is required for NEXTSTEP metering pumps?

NEXTSTEP metering pumps operate on 115/230V AC power, single-phase. The pumps are designed to accept either voltage, with automatic or manual selection depending on the model. The electrical connection is standard for industrial environments. The stepper motor drive converts AC power to controlled DC signals for precise motor control. No additional power conditioning is typically required, but users should verify voltage compatibility with local supply.

What is the turndown ratio of NEXTSTEP pumps and why is it important?

NEXTSTEP pumps have a 3333:1 turndown ratio. This means the pump can deliver flow from its maximum rated capacity down to 1/3333 of that capacity while maintaining accuracy. This wide range allows the pump to handle varying process demands without needing to change pump size or add bypass lines. It is important for applications where flow rates must be adjusted frequently or where precise dosing at low flows is required.

Can NEXTSTEP pumps be used with aggressive chemicals?

Yes, NEXTSTEP pumps are designed for chemical metering and can handle many aggressive chemicals. The PVDF head and PTFE diaphragm provide resistance to a broad range of acids, bases, and solvents. The FKM seal option offers additional compatibility with hydrocarbons and other aggressive media. However, users should verify chemical compatibility with the specific pump materials for their process fluid, as not all chemicals are compatible with PVDF or PTFE.

What control options are available for NEXTSTEP metering pumps?

NEXTSTEP pumps use a stepper motor drive that accepts digital control signals. The pumps can be controlled via analog input (4-20 mA) or digital pulse input, depending on the model. This allows integration with PLCs, flow controllers, or other automation systems. The pumps do not include an onboard controller; external control signals are required. The stepper motor provides precise response to control inputs, enabling accurate flow adjustment.
