Product Overview

Forming the hydraulic wet end of a submersible pump system, the Lowara 8GS55R is a redesigned 4-inch e-GS borehole component. This model is specified for coupling with a 5.5 kW (7.33 HP) electric motor. Well installation allows vertical placement or horizontal mounting inside tanks.

A stainless steel casing houses the multi-stage hydraulics, protecting the internal floating stack. This model is equipped with 33 floating impellers made of wear-resistant polymer. The system handles suspended sand particles up to a maximum of 150 grams per cubic meter.

Upon coupling this pump end to its specified 5.5 kW motor (rated for 13.7 Amps on 415 V three-phase power), the combined unit reaches a maximum head of 186.6 m. It delivers a maximum flow of 183 L/Min through a Rp 2" (50 mm) port. High volumetric delivery is maintained under load.

Continuous service is possible in liquid temperatures reaching up to a maximum of 35°C. The assembly is specified for submergence depths up to 150 meters with a 4OS motor or up to 300 meters with an L4C motor. Horizontal deployment is possible within motor limits. The multi-stage design requires proper coupling with standard motors to maintain correct performance under standard system heads.

FEATURES

  • Features 33 multi-stage floating impellers to drastically limit wear and abrasion from suspended sand particles.
  • Constructed with a sturdy stainless steel outer sleeve to limit corrosion and protect internal hydraulic components.
  • Includes an integrated stainless steel strainer to filter out oversized particles and prevent debris entry.
  • Features a hexagonal pump shaft design that distributes mechanical torque without vulnerable keyed joints.
  • The upper and lower brackets are made of precision-cast stainless steel to establish a sturdy motor coupling.
  • ErP/Ecodesign compliant in accordance with strict European Minimum Efficiency Index of 0.40 or higher.
  • Suitable for continuous submerged operations in liquid temperatures reaching up to a maximum of 35°C.

How deep can the Lowara 8GS55R push water from underground?

With a maximum head of 186 m, it easily lifts water from deep bore shafts and pushes it across long pipe runs without losing pressure.

Will sand in my bore water ruin the Lowara 8GS55R?

It uses Lowara's floating impeller design to handle up to 150 g/m³ of sand without clogging or wearing down internal parts.

Can I run the Lowara 8GS55R off a farm generator or solar inverter?

Yes, as long as your generator matches its 5.5 kW requirement. It's built for continuous duty on 415V three-phase or standard rural power setups.

Is the Lowara 8GS55R safe to use in mineral-heavy or salty groundwater?

The pump uses stainless-steel wetted components; suitability for saline or aggressive water should be confirmed against the manufacturer's liquid-compatibility limits.
