Key design features:

  • Hydrodynamic Sealing: A sealless design that eliminates the need for mechanical seals, ensuring leak-free operation.

  • Outdoor Versatility: Compact vertical configuration specifically ideal for direct installation on outdoor tanks, minimising footprint and piping requirements.

This serie is designed to fit on ISO2858 for high performance.
All internal components are manufactured in a material corrosive.

The BV Vertical Series is built according to ISO 5199 process pump standards, combining exceptional mechanical robustness with optimal hydraulic performance. A standout feature of this series is its advanced hydrodynamic sealing system, which completely eliminates the requirement for mechanical seals, significantly reducing maintenance costs and avoiding the risk of leaks.

For maximum operational safety, the dry-running design allows the pump to operate securely even when liquid levels fluctuate or the suction line empties. The equipment is manufactured from solid plastic with steel reinforcements, a construction choice that ensures superior dimensional stability and high vibration resistance in demanding industrial environments.

Construction & design details

  • Standardisation: Fully compliant with ISO 5199 process pump standards, ensuring maximum mechanical robustness and hydraulic efficiency.

  • Reinforced structure: Features a volute casing machined from solid thermoplastic blocks and reinforced with steel to provide superior dimensional stability and high vibration resistance.

  • Sealless hydrodynamic design: Utilises advanced hydrodynamic sealing technology that eliminates the need for mechanical seals, resulting in a completely leak-free operation.

  • Configuration: Vertical bare-shaft design with a flexible coupling and a heavy-duty baseplate specifically optimised for outdoor tank mounting.

  • Ease of maintenance: The modular assembly allows for straightforward, part-by-part disassembly, facilitating quick servicing without disconnecting main pipework.

  • Maximum discharge head: Up to 100 mcl (328 ft).

  • Duty cycle: Engineered for continuous duty with full dry-running capability.

  • Certifications: Optional ATEX-certified versions are available for safe operation in explosive atmospheres.

  • International Drive Options: Capability to mount standardised motors under IEC (50/60 Hz) or NEMA regulations, adapting the equipment to the global electrical requirements of any facility.

  • Hazardous Area Safety: Optional ATEX certification available to guarantee safe operation in environments with a risk of explosive atmospheres.

  • Connection Standardisation: Suction and discharge flanges configurable according to EN 1092-1 PN16 or ANSI B16.5 150# standards, allowing for direct connection to existing pipework without the need for adapters.

  • Alternative Sealing Configurations: Although the standard design is hydrodynamic (sealless), there is an option to install a double mechanical seal for processes requiring a specific or critical level of tightness.

  • High-Performance Sealing Components: Availability of Variseal systems and internal gaskets manufactured in PVDF to ensure maximum chemical compatibility and durability against aggressive fluids.

  • Advanced Vapour Protection: Incorporation of a lower lip seal specifically designed for the containment of corrosive vapours, protecting the upper mechanical components.

  • Automation & Operational Safety: Optional accessories such as dry-run protection and float systems, allowing for the automation of pumping cycles and preventing failures caused by a lack of liquid.

  • Specialised Thermoplastic Materials: For extremely aggressive applications, the pump column can be manufactured in E-CTFE, further expanding the equipment’s chemical resistance spectrum.

Frequently asked questions – BV Vertical Pumps

The BV Vertical series is specifically engineered for environments where corrosion, abrasion, and reliability are critical factors. Primary sectors include the chemical and petrochemical industries (transfer of acids, alkalis, and solvents), mining and metallurgy (handling abrasive or corrosive slurries), and water and wastewater treatment (WWTP) for recirculation and neutralisation circuits.

It is also the preferred choice for surface finishing and electroplating (acid bath management) and environmental pollution control, specifically for scrubber support and outdoor tank discharge systems.

A standout feature of the BV Vertical series is its advanced hydrodynamic sealing design, which completely eliminates the need for mechanical seals.

By removing the mechanical seal—the most common point of failure and leakage in process pumps—the series ensures a leak-free operation and significantly reduces maintenance costs and downtime. This sealless architecture is ideal for handling toxic or aggressive fluids where external product leakage must be strictly avoided.

Engineered for heavy-duty industrial service, the BV Vertical series provides comprehensive hydraulic coverage. It can deliver a maximum flow rate of up to 1,200 m³/h (5,280 gpm) and reach a maximum discharge head of 100 metres (328 ft).

These performance limits, compliant with ISO 5199 standards, enable the pump to manage high-volume transfers while maintaining exceptional mechanical robustness.

Yes, the series is designed for continuous duty with full dry-running capability. The hydrodynamic design allows the pump to operate safely even if the suction line empties or liquid levels fluctuate, preventing thermal damage.

Furthermore, its construction in solid thermoplastics with steel reinforcements provides the structural rigidity and environmental resistance required for direct, long-term installation on outdoor storage tanks.

To guarantee absolute resistance against a wide spectrum of corrosive and abrasive liquids, all wetted components are machined from high-grade solid thermoplastic blocks.

Depending on the specific chemical application, the series is available in PP (Polypropylene), PE (Polyethylene), PVDF (Polyvinylidene Fluoride), or E-CTFE. For hazardous environments, optional ATEX-certified versions are also available to ensure safe operation in explosive atmospheres.
