Vertical Pumps – BT Series
Heavy-duty reinforced sump pumps for corrosive and abrasive liquids
The BT Series Vertical Sump Pumps from Tecnium are designed for the continuous transfer of corrosive and abrasive fluids from tanks, pits, or sumps. Constructed in solid thermoplastic materials, these pumps ensure reliable operation in harsh chemical environments where metal pumps would quickly deteriorate. Their cantilevered shaft design and dry-running capability make them ideal for applications requiring safe, maintenance-free operation.
.
Design and Construction
BT sump pumps feature a reinforced, cantilevered vertical design that eliminates the need for immersed bearings, making them capable of dry-running operation without damage.
- Depth: up to 1.2 m (47 in)
- Cantilevered shaft: fully supported from the top flange, avoiding submerged mechanical components
- Construction: machined from solid thermoplastics for maximum rigidity and corrosion resistance
- Reinforced column design: ensures stability under high hydraulic loads
- Drive system: direct motor coupling with vertical alignment
The BT Series is available with optional baseplates or custom mounting flanges for direct tank installation.
.
Performance and Range
- Flow rate: up to 450 m³/h (1,980 gpm)
- Head: up to 100 mcl (328 ft)
- Operating depth: up to 1.2 m
- Configuration: single-stage vertical sump design
- Dry-running design: allows intermittent operation without liquid
These performance parameters make the BT Series ideal for continuous industrial service in environments with aggressive chemical compositions or variable liquid levels.
.
Applications
The BT Series is widely used across industries where chemical resistance and reliability are essential:
- Chemical and petrochemical industries – transfer of aggressive acids, alkalis, and solvents
- Water and wastewater treatment (WWTP) – recirculation, sludge transfer, neutralisation tanks
- Mining and metal processing – abrasive slurry and effluent handling
- Surface treatment plants – acid pickling, anodising, and galvanic processes
- Fertiliser and phosphoric acid production – reliable pumping under corrosive atmospheres
