Barmesa 2AHS Series: The Professional Choice for High-Efficiency Submersible Dewatering
The Barmesa 2AHS series is a premier line of submersible dewatering pumps engineered to deliver professional-grade performance in demanding commercial, utility, and construction environments. Available in a versatile power range of 0.5, 1, and 2 HP, these pumps operate at 3450 RPM to ensure rapid water removal and consistent flow for liquids up to 104°F. By integrating a rugged FC-200 cast iron pump body with a lightweight, heat-dissipating ADC12 aluminum alloy motor housing, the 2AHS series offers a superior balance of structural durability and job-site portability. Whether you require the "A" series model for automatic, set-and-forget operation or a manual unit for active site management, these pumps provide a reliable, high-efficiency solution for handling 1/4" solids in a variety of drainage applications.
Precision Engineering: The 2AHS Performance Edge
- Advanced Hytrel® Hydraulics: Features an 8-vane, semi-open Vortex impeller crafted from Hytrel® thermoplastic elastomer, specifically designed to resist wear in abrasive dewatering conditions.
- Industrial Double Seal Protection: Equipped with a double mechanical seal in an oil-filled chamber—utilizing carbon-ceramic upper and silicone carbide lower faces—to provide a redundant barrier against moisture and ensure maximum motor security.
- Extended-Life Lubricated Bearings: Includes single-row ball bearings that are permanently oil lubricated for up to 60,000 hours of work, expertly designed to manage both radial and axial loads.
- Continuous-Duty Rated Motor: Powered by a dry-type submersible motor featuring Class B insulation and a thermal protector in the winding, rated for continuous duty in both single and three-phase configurations.
- Versatile Discharge & Handling: Comes standard with a 2" NPT vertical discharge (adapter included) and a high-strength Nylon 6 handle for easy deployment and positioning.
Hybrid Construction for Durability and Portability
The Barmesa 2AHS series utilizes a sophisticated hybrid material design to provide maximum site longevity without excessive weight. The pump body and oil chamber are cast from high-strength FC-200 cast iron, providing a rugged, vibration-dampening foundation that withstands heavy-duty use in demanding environments. Complementing this strength is an ADC12 aluminum alloy motor housing, which offers superior heat dissipation properties while keeping the unit lightweight and portable for easy deployment across various job sites.
High-Performance Hytrel® Vortex Hydraulics
Engineered for high efficiency in abrasive dewatering environments, the 2AHS features an advanced 8-vane, semi-open Vortex impeller. This critical component is manufactured from Hytrel® thermoplastic elastomer, a material specifically chosen for its exceptional resilience against wear from sand and grit that would typically erode standard impellers. This design allows the pump to manage 1/4" solids reliably while maintaining peak flow rates through its 2" NPT vertical discharge.
Professional-Grade Double Mechanical Seal Protection
To ensure ultimate motor integrity and prevent costly downtime, the 2AHS series is equipped with a professional-grade double mechanical seal system housed in an isolated, oil-filled chamber. The sealing faces utilize a combination of carbon-ceramic for the upper part and silicone carbide for the lower part, providing a redundant, high-durability barrier against moisture ingress. This robust sealing strategy is supported by 304 series stainless steel hardware and nitrile rubber O-rings to ensure long-term leak protection.
