HW Series Stainless Steel Self-Priming Explosion-Proof Pumps — Reliable and Safe Liquid Transfer
In industries where precision, safety, and durability are essential, the HW series stainless steel self-priming explosion-proof pumps deliver an unmatched solution. Independently developed with advanced design, these pumps feature a semi-open impeller and high-quality stainless steel construction for both the flow components and connecting frame. This ensures excellent corrosion resistance, robust performance, and minimal maintenance requirements. Compact and energy-efficient, HW pumps also provide reliable sealing, eliminating the need for a bottom valve in the pipeline. Before operation, simply ensure a small amount of pilot liquid is present in the pump body for immediate use.
The HW series is designed for versatility and extreme conditions. They can handle liquids with temperatures ranging from -40°C to 150°C and can transport fluids containing small soft particles or fibers, whether corrosive or requiring hygienic handling. These pumps are widely used in industries such as food and beverage production, pharmaceuticals, wastewater treatment, chemical processing, electroplating, bleaching and dyeing, and fine chemicals. Importantly, they are suitable for flammable or explosive media, including urea solutions, AdBlue, methanol, xylene, gasoline, and diesel, making them ideal for both industrial and fuel transfer applications.
Safety and operational conditions are clearly defined for optimal performance: the pump impeller can be immersed up to 10 meters into the liquid, and the fluid pH should be compatible with stainless steel 304 standards (pH 4–10). Explosion-proof electric motors are available in single-phase 220V or three-phase 380V configurations, ensuring compliance with international safety standards.
HW series pumps are recognized globally under various names, highlighting their adaptability:
Europe: Stainless Steel Explosion-Proof Self-Priming Pump / AdBlue Pump
North America: Digital AdBlue Transfer Pump / Chemical Self-Priming Pump
Asia: 防爆不锈钢自吸泵 / AdBlue液体输送泵
The Latin America: Bomba Autocebante a Prueba de Explosión de Acero Inoxidable
Southeast Asia (Vietnam, Thailand, Indonesia, Malaysia): Máy bơm tự mồi chống cháy nổ / Flow Pump for Chemical Liquids
HW series offers a range of models with different inlet/outlet sizes, voltage and power ratings, and flow rates. From 3 m³/h to 13 m³/h and horizontal transfer distances up to 22 meters, users can select the model that best fits their specific industrial or fuel transfer needs. The modular and flexible design allows seamless integration into pipelines and processing systems, providing a cost-effective and highly reliable solution for industrial liquid management.
Whether it is for AdBlue dispensing, chemical transfer, or food-grade liquid handling, the HW series stainless steel self-priming explosion-proof pumps deliver unmatched safety, precision, and operational efficiency, making them a trusted choice for industries worldwide.
