Industrial Pumps
ST Series Pumps
MERAJ builds the ST Series for heavy-duty industrial process handling. These centrifugal pumps efficiently move water, chemicals, petroleum, wastewater, oil, sludge, slurry, and food. Operators use these end-suction, non-clogging pumps for diverse industrial and firefighting applications.
Industrial Pumping Excellence
Versatile Mounting Configurations
The ST Series supports multiple installation methods. Technicians can configure them using close-coupled, SAE engine-mount, horizontal frame-mount, vertical, or vertical coupled setups.
Advanced Construction Materials
We manufacture these pumps from Iron and CD4MCu stainless steel. The stainless steel variant provides corrosion resistance equal to or better than 316 SS and delivers double the yield strength.
Direct Pipeline Integration
These units function perfectly as booster pumps. The design allows operators to bolt them directly into existing pipelines.
Reliable Dry-Run Operations
The pump features a two-vane closed impeller and oil-lubricated seals. This engineering provides complete dry-run capability to protect the equipment during fluid interruptions.
Features
Flexible Drives
Supports hydraulic drives with variable speeds and works with electric drive setups.
Broad Applications
Handles sewer systems, dewatering, canneries, dredging, foundries, and construction sites.
Massive Output
Reaches a maximum flow rate up to 32,000 GPM.
Powerful Delivery
Generates a maximum head of up to 450 feet.
