A Series Submersible Electric Pumps

A Series Submersible Non‑Clog Pumps: Engineered for Demanding Wastewater & Industrial Applications

The BJM A Series is engineered for high‑performance pumping in tough industrial, municipal, and commercial environments. Built from heavy‑duty cast iron and equipped with open channel impellers, these submersible pumps deliver dependable flow, long service life, and consistent operation in applications where solids handling and reliability are essential. With both 2‑pole and 4‑pole motor options, the A Series provides the flexibility to match your required head, flow, and operating conditions.

Designed to handle everything from clear liquids to sewage and process wastewater, the A Series combines rugged construction with smart protection features, including the Seal Minder® moisture‑sensing probe, dual mechanical seals, and thermal overload protection. These pumps are built to stay online longer, reduce maintenance interruptions, and keep critical systems moving.

Built for Reliability in Harsh Environments

The A Series is engineered around a robust mechanical and electrical architecture designed to maximize service life:

Durable Construction: Heavy-duty GG25 cast iron components ensure long service life in abrasive and corrosive environments.

Efficient Impeller Design: Open single‑channel impellers allow smooth passage of solids,  reducing clogging and improving uptime.

Seal Minder® Moisture Probe: Standard on all models, providing early warning of seal chamber moisture intrusion.

Dual Mechanical Seals: Carbon/ceramic upper and silicon‑carbide lower seals ensure long‑term protection in abrasive or contaminated liquids.

Thermal Motor Protection: Integrated thermal overload switches protect the motor from overheating.

Application Flexibility: Designed to handle clear liquids, sewage, wastewater, and agricultural runoff with consistent reliability.
