Submersible Pumps
With centrifugal principles, the submersible pumps operate submerged at the harvesting site, displacing high volumes of fluids in several applications, such as underground water supply, irrigation, industrial processes, or urban flood drainage. The practical and flexible installation easily adapts to different scenarios and necessities, eliminates the need for alignment, reduces costs and ensures high efficiencies.
Concepts and Features
With the principle of centrifugal pumping through mixed, radial or axial flow impellers, Single or multi-stage, the submersible pump has been designed to have the ability to operate submerged at the collection site, displacing high volumes of fluid. The submerged operation ensures excellent thermal exchange between the motor set and the pumped fluid.
The motor is internally cooled out with water. The winding is manufactured with coated wire spirals which guarantee insulation and allow rewinding. The HIGRA’s technology axial and radial bearings ensure centralization and absorb vibrations and stresses resulted from rotary movement, absorbing as well as hydraulic thrust and pressure over the centrifugal impeller.
Main advantages of the Submersible System
- Motor and pump are a single compact and light monoblock system
- Asynchronous electric submerged motor, squirrel cage type, in short circuit and wet winding
- Submersible motor that allows excellent cooling and eliminates the cavitation and NPSH issues
- Easy installation
- No need for machine housing structures at river banks, avoiding damages in permanent preservation areas
- Electric motor that runs with frequency converter, allowing speed variation
- IV pole motor
- Sealing system with mechanical seal

Irrigation Systems Feed
Higra submersible pumps offer low cost and versatile installation. They are installed over rails, floats or directly connected to the discharge tubing, with no need for alignment.
Applied to many different situations, they meet all types of irrigation: flooding (rice), center pivot (sugar cane, corn and soyabeans), self-propelled irrigation (orange) or drip irrigation (orange, sugar cane and vegetables).
The flexible installation adapts to different submerged applications and irrigation systems, meeting the needs of several different cultivations.
Choosing HIGRA submersible pumps brings practicality, efficiency, and great results to irrigation projects, contributing for the environmental sustainability.
