Portuguese manufacturer since 1992
JOVAL – Quality and Innovation in Submersible Pumps
At JOVAL, we develop technical solutions for water abstraction, pressurization, and drainage with a single focus: reliability, durability, and real technical support.
With over 30 years of activity, we have created a solid technical line that includes submersible pumps, hydropneumatic sets, control panels, motors, tanks, and specialized accessories, with versions adapted to agricultural, industrial, and residential applications.
Our Mission
Our mission is clear: create value through engineering applied to water. More than selling equipment, JOVAL provides complete solutions that keep thousands of hydraulic systems running, from farms in Portugal to industrial facilities in Northern Europe.
We build relationships of trust with distributors and installers, maintaining technical proximity, reliable deliveries, and a team available to support every project.
Innovating in Pumping Systems Since 1992
Foundation in Fafe
JOVAL was born from the technical experience of Valdemar, Jorge, and Orlando Marinho Oliveira, responding to the real challenges of water abstraction in the agricultural sector.
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
Consolidation in the European market with solid presence in Spain, Scandinavia, and Eastern Europe. ISO 9001 certification reinforces quality commitment.
New Generation, Same DNA
Management assumed by a new generation of the founding family, maintaining the industrial DNA: proximity, practical engineering, and commitment to field workers.
Presence and Future
Currently, JOVAL operates mainly in the European market, with a solid presence in countries such as Spain, Scandinavia, and Eastern Europe. Although the focus is on Europe, the company maintains the capacity to respond to projects in other geographies whenever the technical context justifies it.
Management is now assumed by a new generation of the founding family, which maintains the company's industrial DNA: proximity, practical engineering, and commitment to those who work in the field.
More than a brand, JOVAL continues to be a company where every component has a purpose: making water reach where it is needed — with stability, efficiency, and real support.
At JOVAL, services do not start at 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 — is delivered with clear technical documentation and continuity guarantee.
Real Support
For us, service does not end at delivery — it starts with it. After-sales service and technical assistance are pillars of our operation.
Technical Partnership
We are technical partners, not occasional suppliers. Our commitment is to keep systems running, with stable solutions, competent assistance, and direct communication.
