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 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.
Firefighting
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, restoration 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 — our 24/7 field service puts a field crew at the plant with the urgency operations demand, in any region of Brazil.

Questions from plant operators
Do you service pumps without an active manufacturer or drawings?
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.
Can you work within the planned outage window?
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 window. The schedule commitment is treated as a contract requirement, not an internal target.
Do you maintain vertical drainage pit pumps?
Yes — vertical turbine pumps are our specialty: complete disassembly, restoration of columns, line shafts and bowl assemblies, balancing and in-plant erection with dimensional and alignment reports.
Do you issue reports and documentation for the power sector?
Every intervention ships with a technical report: inspection with photographic record, dimensionals of restored parts, balancing certificate with G2.5 residual and test reports. The documentation meets internal audits and the sector's maintenance requirements.
