Barmesa 2AHS Series: Engineered for Resilience in Every Dewatering Application

For professionals in construction, utility, and commercial maintenance, the Barmesa 2AHS series is the premier choice for high-efficiency dewatering. These submersible pumps are engineered to deliver rapid water removal with a high-speed 3450 RPM motor, handling liquids up to 104°F and solids up to 1/4" in diameter. Available in 0.5, 1, and 2 HP models, the series provides a scalable solution for everything from minor water transfer to heavy-duty site drainage.

Engineered for Strength and Portability

The 2AHS series features a sophisticated hybrid construction that prioritizes both structural integrity and ease of use on the job site. The pump body and oil chamber are cast from FC-200 cast iron, providing a rugged, vibration-resistant foundation for demanding environments. To ensure the pump remains portable, Barmesa utilizes an ADC12 aluminum alloy motor housing, which offers superior heat dissipation while keeping the unit light enough for quick deployment.

Advanced Hydraulics and Motor Protection

Reliability is built into every component, starting with the 8-vane, semi-open Vortex impeller. Crafted from Hytrel® thermoplastic elastomer, the impeller is uniquely resistant to the abrasive wear of sand and grit. To protect the internal motor, the series utilizes a double mechanical seal in an oil-filled chamber, featuring silicon carbide and carbon-ceramic faces that act as a redundant barrier against moisture ingress.

Long-Term Operational Efficiency

These pumps are designed for a high "total cost of ownership" value through maintenance-free longevity. The single-row ball bearings are permanently oil-lubricated and rated for an impressive 60,000 hours of work, expertly managing both radial and axial loads during operation. Furthermore, the dry-type motor includes Class B insulation and a built-in IP68 thermal protector, making it safe for continuous duty in both single and three-phase applications.

Applications: 

Septic / Sump, Basement Draining, Utilities, Flood & Pollution Control, Residential, Commercial, Industrial

Choosing the Right Model for Your Project

Selecting the correct 2AHS unit depends on your specific installation needs. If you require a "set-and-forget" solution for a permanent sump or utility vault, the "A" Automatic model includes an integrated level switch for autonomous operation. For active job site dewatering where an operator is present, the Manual model offers direct control. Note that while single-phase models are plug-and-play, three-phase pumps require a separate control panel to manage automatic operation.

Ready for Immediate Deployment

Every pump in the series comes standard with user-focused features, including a high-strength Nylon 6 handle for secure carrying and a 410 series stainless steel shaft for corrosion resistance. The inclusion of a durable PVC strainer ensures that large debris is filtered out before it can reach the hydraulics, maintaining consistent flow and preventing clogs. This combination of professional-grade materials and versatile design makes the 2AHS a reliable staple for any industrial tool kit.
