From Local Lift Stations to Large Wastewater Systems: The Expanded BJM Pumps® A Series
Municipal wastewater systems come in all sizes. A neighborhood lift station may handle modest flows, while a master lift station or wastewater treatment facility may move thousands of gallons per minute.
No matter the system size, the challenge remains the same: keep wastewater moving reliably.
To provide municipalities, engineers, and operators with more options across a wider range of applications, BJM Pumps® has expanded it’s A Series submersible wastewater pump line with new high-capacity A4L models.
The expanded range takes the A Series from small and medium wastewater applications to large municipal infrastructure, providing a scalable family of non-clog pumping solutions for today’s wastewater systems.
The new A4L models have a maximum head of 59.1 m (194 ft), flow rate of 1367 GPM, and can manage solids up to 142 mm (5.6 in).
One Series. A Wider Range of Municipal Applications.
Pump requirements can vary significantly throughout a municipal wastewater collection system.
A local lift station serving a residential development has very different flow and head requirements than a regional or master lift station handling wastewater from a much larger service area. Wastewater treatment plants and other major infrastructure can require even greater pumping capacity.
The expanded A Series gives engineers and operators more options to match the pump to the application.
A2 and A4 models provide reliable solids-handling performance for small and medium wastewater systems, including:
- Local municipal lift stations
- Residential developments
- Commercial wastewater
- Industrial wastewater collection and transfer
For applications needing significantly greater capacity, the new A4L models extend the A Series into larger municipal and industrial wastewater systems, including:
- Master lift stations
- Regional lift stations
- Wastewater treatment plants
- High-flow wastewater applications
With the expanded range, municipalities can look to the A Series for pumping solutions across more of their wastewater infrastructure.
More Capacity for Demanding Wastewater Systems
As wastewater systems grow, so do the demands placed on pumping equipment.
Higher incoming flows require greater pumping capacity, while larger collection systems may also face considerable solids and debris. Selecting a pump that meets the station’s hydraulic requirements while reliably passing solids is critical to maintaining system performance.
The expanded A Series addresses both.
Across the A Series family, available models now provide flow capacities ranging from applications below 200 GPM to models capable of more than 3,000 GPM, depending on the required duty point.
The larger A4L models also significantly increase solids-passing capability, with select models capable of passing solids up to 5.6 inches (142 mm).
That combination of high flow and large solids passage makes the expanded range particularly well suited for demanding municipal wastewater applications.
Designed to Keep Wastewater Moving
Capacity is only part of the equation. Municipal wastewater pumps must operate reliably in an environment where solids, debris, and changing flow conditions are part of everyday operation.
BJM Pumps® A Series pumps feature open-channel impellers designed for efficient, non-clog wastewater pumping. Depending on the model selected, the expanded range provides options for different flow, head, discharge, and solids-handling requirements.
Additional A Series features include:
- Durable GG25 cast iron construction
- Open-channel impeller designs
- 2-pole and 4-pole motor options
- Seal Minder® Probe standard on all models
- Multiple pump sizes and performance ranges to match application requirements
Together, these features deliver a versatile pumping platform designed for long service life and reliable wastewater handling.
A Scalable Solution for Municipal Wastewater
No single pump size fits every lift station, and it shouldn’t.
The goal is to select a pump that meets the application’s actual requirements, including flow, total dynamic head, solids characteristics, discharge size, operating conditions, and future system demands.
By expanding the A Series into higher-capacity applications, BJM Pumps® now provides municipalities and engineers with a wider range of options within one product family.
From a smaller lift station serving a local community to a high-capacity regional station moving thousands of gallons per minute, the expanded A Series scales with the needs of municipal wastewater infrastructure.
Find the Right A Series Pump for Your Application
Every wastewater pumping application is different. Industrial Flow Solutions can help evaluate your flow, head, solids-handling, and system requirements to identify the appropriate BJM Pumps® A Series model for your application.
