ABB expands certified vertical pump motors for Mexico

In water infrastructure, irrigation systems, and industrial pumping applications, compliance with local regulations and reliable motor performance are critical for long-term operation. ABB has expanded its Vertical Hollow Shaft (VHS) motor portfolio in Mexico with NOM/ANCE certification, enabling deployment across regulated sectors such as municipal water, wastewater treatment, mining, and agriculture.

Certified motors aligned with Mexico’s regulatory framework
The introduction of NOM (Normas Oficiales Mexicanas) and ANCE certification ensures that ABB’s VHS motors meet mandatory national requirements for safety, energy efficiency, and product conformity. These certifications are essential for legal commercialization and integration into public and private infrastructure projects in Mexico.

ANCE certification involves testing and verification of electrical performance, manufacturing consistency, and compliance with applicable NOM and NMX standards. This reduces regulatory barriers for system integrators, OEMs, and operators specifying motors for pumping systems.




Designed for vertical pumping systems and high-load conditions
Vertical Hollow Shaft motors are specifically engineered for vertical pump configurations, commonly used in deep well extraction and high-capacity fluid handling. ABB’s VHS motors are designed to manage axial loads associated with vertical pumping, with high-thrust capability reaching up to 175% additional thrust for larger frame sizes.

The motors are available in a power range from 15 to 500 horsepower and support multiple voltage and frame configurations, allowing adaptation to different system requirements. Their NEMA-based design ensures compatibility with existing installations, enabling drop-in replacement in retrofit projects.

Maintenance-oriented design for operational continuity
Operational uptime in water and industrial systems depends heavily on ease of maintenance. The VHS motors incorporate a top-mounted coupling configuration, providing direct access to pump components and simplifying servicing procedures.

An integrated sight glass allows operators to visually inspect thrust bearing lubrication without disassembly, reducing inspection time and minimizing the risk of unexpected failures. These features are particularly relevant in remote or large-scale pumping installations where downtime can impact supply continuity.




Efficiency and compatibility with modern drive systems
The motors meet NEMA Premium (IE3) efficiency levels, supporting reduced energy consumption in continuous-duty pumping applications. They are also inverter-duty rated, enabling integration with variable frequency drives (VFDs) for speed control and energy optimization.

Additional mechanical features, such as non-reverse ratchet mechanisms, prevent reverse rotation caused by backspin in vertical pump systems—an important safeguard in high-inertia applications.

Applications in water management and industrial sectors
The certified VHS motors are suited for:

In these contexts, the combination of regulatory compliance, high-load handling, and serviceability supports reliable and efficient system operation.




Position within the vertical pump motor market
Vertical Hollow Shaft motors are widely used in pumping applications, with comparable offerings available from manufacturers such as WEG and Siemens. Key selection criteria typically include thrust capacity, efficiency class, enclosure type, and compliance with regional standards.

ABB’s expansion in Mexico is characterized by its alignment with NOM/ANCE requirements and its focus on maintenance accessibility and compatibility with existing infrastructure, addressing both regulatory and operational considerations.
