Motor Pumps – BH Series
High-performance thermoplastic pumps for corrosive and abrasive fluids
The BH Series Direct Coupled Pumps from Tecnium are compact, high-performance motor pumps specifically designed for the transfer of corrosive and abrasive fluids. Constructed entirely from solid thermoplastic materials, they provide outstanding resistance to aggressive chemicals and mechanical stress, ensuring long-term reliability in demanding industrial environments.
Design and Construction
The BH Series features a direct-coupled motor configuration, eliminating the need for a separate bearing frame and simplifying installation and maintenance.
These pumps are machined from solid plastic blocks, providing excellent mechanical rigidity and dimensional stability under varying thermal and chemical conditions.
- Compact, integrated motor-pump design for space-saving installations.
- Solid thermoplastic construction ensures chemical and corrosion resistance.
- Hydraulic design optimised for smooth, low-vibration operation.
- Fully interchangeable with standard IEC motor frames.
- Optional ATEX-certified versions available for explosive atmospheres.
Performance and Range
- Flow rate: up to 250 m³/h (1,100 gpm)
- Head: up to 80 mcl (262 ft)
- Configuration: single-stage centrifugal pump
- Drive system: direct motor coupling
- Operation: continuous duty under heavy industrial loads
This performance profile makes the BH Series ideal for process industries requiring robust, efficient, and chemically resistant pumping solutions.
Applications
Tecnium BH pumps are suitable for a wide range of industrial applications, particularly where corrosion and abrasion are major concerns:
- Chemical and petrochemical industries – transfer of acids, alkalis, and solvents
- Water and wastewater treatment (WWTP) – dosing, neutralisation, and recirculation
- Surface treatment and electroplating – pumping aggressive process baths
- Mining and metallurgy – handling abrasive slurries and chemical effluents
- Fertiliser and acid production – continuous service under corrosive environments
