Factory in Fafe since 1992
Factory, documentation and a technical counterpart
Own lines in Fafe and direct support for distributors, importers, OEM partners and specifiers. The JOVAL brand also includes partner-origin families.
Our mission
We help distributors, importers and OEM partners keep pumping equipment working in the field. Fafe lines leave with documentation and a bench test; technical support speaks to the factory.
We work with people who need supply continuity, a clear origin and technical answers without intermediaries.
In pumping systems since 1992
Foundation in Fafe
JOVAL started in Fafe in 1992, from a family hydraulic-pumping workshop serving agricultural water abstraction.
Product line expansion
Evolution from specialized workshop to manufacturer with its own product line — submersible pumps, control panels, hydropneumatic sets, and technical accessories.
European market expansion
Exports grew to Spain, Scandinavia and Eastern Europe. ISO 9001 certification now frames our design, manufacturing and marketing processes.
New generation in the factory
Management has moved to a new generation of the founding family, keeping the factory in Fafe and the focus on practical engineering, technical proximity and support for field work.
European presence
JOVAL exports to more than 15 European countries, with customers in Spain, Scandinavia and Eastern Europe. We keep manufacturing in Fafe and respond to projects outside Portugal when the technical context fits.
Our priority is a direct relationship with distributors, installers and project designers, from equipment selection to after-sales support.
Every product should have a clear function: getting water to the right place, with stable operation, efficiency and technical support when needed.
Technical support starts before the sale
From the first contact, we help define the right solution, taking into account the type of application, power source, site conditions, and performance goals.
Our technical team is prepared to support distributors, installers, and designers at all stages of the process: requirements analysis, equipment selection, assisted installation, control panel configuration, and after-sales advice.
Clear documentation
Every component we supply — pumps, sets, motors, tanks, or accessories — includes complete technical documentation: product sheets, performance curves, and installation instructions accessible online and in PDF.
Direct technical support
After delivery, we keep technical support available for installation, assistance and replacement component selection.
Technical partnership
We act as a continuous technical contact for distributors and installers, helping solve questions and keep systems running.
Online technical tools
Datasheets and performance curves sit on the public catalogue. The hydraulic calculator covers pre-sizing.
