A Series Submersible Electric Pumps with Open Channel Impellers

The BJM A Series is built for operators who need dependable, high‑efficiency pumping in environments where solids, sludge, and wastewater are part of everyday operations. Constructed from GG25 cast iron and equipped with open single‑channel impellers, these pumps are built for reliability in municipal, industrial, agricultural, and commercial environments. Each model includes the Seal Minder® Probe for early detection of seal issues, helping prevent unexpected downtime and extending pump life.

Engineered for Durability

The A Series is built around a robust cast iron pump body, volute, and impeller, providing the structural strength required for continuous operation in harsh wastewater and industrial settings. Stainless steel components, including the cable gland and rotor shaft, add corrosion resistance and long‑term reliability. Dual mechanical seals, carbon/ceramic on the upper and silicon carbide/silicon carbide on the lower, ensure dependable sealing performance even in abrasive or contaminated fluids.

Hydraulics & Motor Performance

The A Series utilizes open single‑channel impellers designed for efficient solids passage and reduced clogging. Depending on the model, the pumps handle solids from 1.6 inches up to 3.6 inches, making them suitable for sewage and debris‑laden liquids. Motors are available in 2‑pole (3450 RPM) for higher head applications or 4‑pole (1750 RPM) for higher flow and improved solids handling. All motors include thermal overload protection and are rated for continuous duty when installed at the proper submersion depth.
