Exclusive technology
HIGRA Amphibious Technology
The amphibious concept is a pioneering HIGRA technology, developed so the pump can operate both submerged and out of water, with no adaptations or auxiliary cooling systems.
In this concept, water is admitted through the flanged axial suction, passes through the centrifugal impeller and flows internally through the pump-motor assembly, providing continuous motor cooling even in above-water operation. This architecture eliminates the need for an oil chamber, external mechanical seals and additional cooling systems, resulting in simpler, more reliable equipment with a longer service life compared with conventional technologies.
Wet Motor
Motor cooled by the pumped water flow itself, with no oil or grease.
Monobloc
Motor and pump integrated on a single shaft, with no external couplings, for greater robustness and lower maintenance.
Oil-Free Technology
Oil-free operation, eliminating environmental contamination risks and leaks.
Axial Suction
Flanged front suction with favorable hydraulic conditions, contributing to better NPSH and high efficiency.

6 Installation Methods
The HIGRA Amphibious Pump adapts to the environment, not the other way around. From above-water suction to in-line booster duty, a single technology solves different operating scenarios.
Submerged
Fully submerged equipment. Ideal for intake in rivers, ETAs and irrigation systems with a stable water surface.
Partially Flooded
Indicated for intakes with a shallow water surface. Amphibious operation ensures efficient suction even when partially submerged.
Modular
Set of pumps in series or parallel to increase flow or pressure. Ideal for high-capacity drainage or long lines.
Suction
Installation above the water level. HIGRA amphibianism delivers the same efficiency as submerged operation when NPSH conditions are met.
Booster (In-Line)
Installed in the pipeline for pressure boosting. Compact solution for long transmission mains and distribution networks.
Barge
Pump on a floating structure. Follows river level variation. Relocates easily and minimizes environmental impact in APPs.
Wet Motor, Monobloc and Oil-Free
Three design principles that make HIGRA Amphibious Pumps superior in reliability, service life and total cost of ownership.
Wet Motor
Motor cooled by the pumped water flow itself, with no oil or grease. No need for air conditioning, forced ventilation or oil changes.
Result: stable operating temperature regardless of external thermal load.
Monobloc
Motor and pump integrated on a single shaft, with no external flexible coupling. Eliminates misalignment, reduces vibration and simplifies maintenance to a single rotating assembly, delivering greater robustness.
Result: fewer critical components, faster replacement and a smaller spare parts inventory.
Oil-Free Technology
Oil-free operation, eliminating environmental contamination risks and leaks. The motor runs entirely with water as the cooling fluid and bearing lubricant, in a cleaner and more sustainable solution.
Result: clean technology, approved for environmental protection areas (APPs) and potable water intakes.
Simulation with CFD Technology
At HIGRA, hydraulic performance is not based on estimates or generic catalog curves. All Amphibious Pumps are developed, simulated and validated using CFD (Computational Fluid Dynamics) software before they go into production. Every detail of fluid mechanics is analyzed computationally to maximize efficiency, operating stability and performance at the application's duty point.
- Dedicated CFD simulation: every aspect of the hydraulic geometry is analyzed and optimized digitally before manufacturing
- Certified hydroenergetic tests: all designs are validated in an in-house laboratory
- Real performance curves: flow, pressure, efficiency, power and NPSH delivered with each unit
- Guaranteed duty point: contracted performance validated for the exact application specification
