The BV series centrifugal pumps are heavy-duty process pumps manufactured from solid plastic, meticulously engineered to handle highly aggressive fluids under the most demanding industrial conditions.

Key design features:

  • Solid construction: Engineered from solid thermoplastic blocks for maximum chemical resistance.

  • Modular maintenance: Horizontal configuration featuring a flexible coupling, allowing for straightforward, part-by-part disassembly to significantly facilitate servicing.

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

The BV series is characterised by an exceptionally robust construction, specifically tailored for the most severe industrial applications. A defining feature of this range is that the volute casing and critical wetted components are machined directly from solid thermoplastic blocks, rather than using standard injection moulding techniques. This manufacturing approach guarantees absolute corrosion resistance and unmatched structural integrity, even when transferring the most aggressive, toxic, or highly concentrated chemicals within the industry.

Furthermore, these heavy-duty centrifugal process pumps are meticulously engineered to withstand high operating pressures and deliver an extended, reliable service life under extreme operational environments. By combining superior hydraulic performance with a highly adaptable design, the BV series ensures maximum plant safety whilst significantly reducing operational downtime and total cost of ownership.

Frequently asked questions – BV Process Pumps

Due to their exceptional construction machined from solid plastic blocks, BV pumps are the ideal solution for handling highly corrosive, toxic, and abrasive fluids under extreme conditions. Consequently, they are routinely installed in the chemical industry, pharmaceutical industry, and fertilisers industry.

Furthermore, their extreme robustness makes them indispensable in waste water treatment plants, potable water treatment plants, large-scale desalination plants, the steel industry (surface treatment), the mining industry, and applied engineering, where equipment reliability is vital to avoid costly production downtime.

The BV series pumps stand out for their ability to handle large volumes of fluids in heavy-duty industrial applications. They offer comprehensive hydraulic coverage, operating with flow rates reaching up to 1,500 m³/h and achieving discharge heads of up to 150 metres.

These elevated performance levels allow plant engineers to precisely tailor the equipment to the specific demands of their installation, ensuring a constant flow even against high system pressures.

Absolutely. We understand that many industrial facilities in the chemical and mining sectors feature critical environments. Therefore, Tecnium manufactures specific versions of the BV series that strictly comply with the ATEX directive (94/9/EC).

This certifies that the equipment can be safely installed and operated in classified areas and potentially explosive atmospheres, minimising operational risks and ensuring compliance with the strictest safety regulations.

Our entire range of process pumps is designed and manufactured to the highest industrial standards, fully complying with ISO dimensional standards and the European Machinery Safety Directives (CE marking).

In addition, the entire process, from conceptual engineering to final assembly, is supported by a strict quality assurance system certified under DIN EN ISO 9001, which guarantees exact tolerances and a long service life for the equipment.

Yes, the modular design of the BV series is specifically intended to reduce operational downtime. Featuring a horizontal, baseplate-mounted configuration connected via a flexible coupling, it allows for part-by-part disassembly.

This means that maintenance personnel can extract critical internal components, such as the mechanical seal or the impeller, for inspection or replacement without needing to disconnect the pump casing from the main pipework, thereby greatly optimising service times.
