Product Overview
Designed for borehole applications, the Lowara 8GS75 represents a high-efficiency hydraulic wet end within the e-GS line. This pump end must be coupled with a 7.5 kW (10.0 HP) motor to become fully operational. Standard well installation is vertical, though horizontal deployment is permissible.
An outer sleeve of stainless steel protects the multi-stage hydraulic pathways. The assembly utilizes 50 floating impellers made of PC/PPO + PS polymer components. The system handles suspended sand up to a maximum concentration of 150 grams per cubic meter.
Pairing this multi-stage wet end with a compatible 7.5 kW motor (rated at 18.7 Amps on a 415 V three-phase connection) enables a maximum head of 282.7 m. The pump end delivers a maximum flow of 183 L/Min through its Rp 2" (50 mm) outlet. Flow parameters follow manufacturer data.
The pump end is specified for continuous water temperatures up to a maximum of 35°C. Submergence limits are 150 meters with 4OS motors and up to 300 meters with L4C motor options. Horizontal installation is possible up to standard motor-rated power limits. The multi-stage design requires proper coupling with standard motors to maintain correct performance under standard system heads.
FEATURES
- Equipped with 50 multi-stage floating impellers designed to minimize abrasive wear from sand particulates.
- The external sleeve is fabricated from durable stainless steel to prevent rust and prolong operating life.
- Includes a built-in stainless steel non-return valve in the discharge head to prevent damaging backflow.
- The hexagonal shaft distributes mechanical torque evenly, eliminating vulnerable keyed connections.
- Features precision-cast stainless steel upper and lower brackets to maintain alignment with the motor.
- Complies fully with the Minimum Efficiency Index threshold of 0.40 under European ErP directives.
- Designed to safely handle water temperatures up to 35°C in continuous underwater applications.

Which electrical supply and motor rating are necessary to power this borehole unit?
Electrical input for the 8GS75 is specified at 7.5 kW on a 380–415 V, 50 Hz, three-phase supply, drawing approximately 18.7 A.
Does this submersible pump include a discharge check valve and support horizontal layout?
Integrated into the delivery casing, an integrated stainless-steel non-return valve protects the 8GS-75 from backflow, and horizontal operation is permitted at a minimum recommended 3° incline with the motor at the lowest position.
How much total vertical column pressure can this borehole pump generate from depth?
Delivering strong vertical pressure, the 8 GS 75 provides a peak dynamic head rating of approximately 282.7 m to push water up from deep subterranean wells.
Which plumbing thread connects to the discharge port and what maximum water flow is delivered?
Plumbing connections attach to the 50 mm (Rp 2") discharge head, enabling the 8_GS_75 to supply a peak flow rate of approximately 183 L/Min inside standard 4-inch (100 mm) or larger borehole casings.
What corrosion defense and wear resistance does this submersible pumping unit provide?
Engineered to withstand corrosive groundwater environments, the 8GS75 utilizes stainless steel external casing with floating impellers made of PC/PPO + PS polymer and provides abrasion-resistant durability up to 150 g/m³.
