Pump maintenance for hydroelectric power plants
In a power plant, a stopped pump is never just a stopped pump: drainage, dewatering and cooling systems protect machines whose downtime is measured in megawatts. Hydro Pumps was born serving the power sector — and masters what is most specific to it: large vertical pumps, discontinued equipment and maintenance windows that cannot slip.
A power plant's pumping systems
From pit drainage to service water, each auxiliary system has its criticality — and its pumps.
Drainage and dewatering
Vertical and submersible pumps keeping pits and galleries dry — the powerhouse's last line of defense against flooding.
Bearing and generator cooling
Cooling water circuits whose failure overheats bearings and forces a unit shutdown — reliability is everything.
Service water
Auxiliary systems feeding seals, heat exchangers and plant utilities — continuous operation, year round.
Gate and regulation pumps
Auxiliary hydraulic systems for gate operation and level regulation.
Fire fighting
Pumps that must work in the one hour they cannot fail — maintenance with documented testing.
Legacy equipment
Pumps with decades of operation, extinct manufacturers or discontinued lines — the classic reverse engineering case.
Why power plants trust critical pumps to Hydro Pumps
Specialists in the fleet's size and age
Brazil's hydroelectric fleet is decades old — and so are its pumps. Much of the equipment we service no longer has an active manufacturer, an available drawing or catalog spare parts. Our reverse engineering solves exactly that: we measure the part, rebuild the drawing and manufacture in material equal or superior to the original.
Large vertical turbine pumps — the most common in plant drainage and intake — are our specialty: disassembly, recovery of columns, shafts and bowls, assembly balancing and in-plant erection with documented alignment.
The outage window is a commitment, not an estimate
Power plant maintenance happens inside windows negotiated with operations — delay means unit unavailability. We work with prior inspection, a work plan closed before the outage and critical parts in hand before disassembly.
For emergencies — pit flooding, cooling failure — the 24h assistance puts a field crew at the plant with the urgency operations demand, in any region of Brazil.

Questions from plant operators
Yes — it is one of the most frequent cases in power plants. We reverse engineer from the part itself: dimensional measurement, drawing reconstruction and manufacture in equal or superior material. Each equipment's history is documented for future interventions.
That is the standard of our service to the sector: inspection before the window, work plan and critical parts secured before disassembly, crew sized for the deadline. The schedule commitment is treated as a contract requirement, not an internal target.
Yes — vertical turbine pumps are our specialty: complete disassembly, recovery of columns, line shafts and bowl assemblies, balancing and in-plant erection with dimensional and alignment reports.
Every intervention ships with a technical report: inspection with photographic record, dimensionals of recovered parts, balancing certificate with G2.5 residual and test reports. The documentation meets internal audits and the sector's maintenance requirements.
