Product Overview
The Lowara 4GS30 pump end is a multi-stage hydraulic wet end designed for borehole extraction in the e-GS range. Starting operation requires coupling the unit with a 3.0 kW (4.0 HP) motor. Standard structural configuration allows vertical mounting or horizontal deployment.
The pump end uses a stainless steel external casing to prevent corrosion. The floating impeller system incorporates 35 stages fabricated from wear-resistant polymer. This multi-stage setup handles suspended sand up to a maximum of 150 grams per cubic meter.
Coupled with the required 3.0 kW motor drawing a nominal current of 7.1 Amps on 415 V three-phase supply, the pump end achieves a maximum head of 204.0 m. This system provides a maximum flow of 90 L/Min via its Rp 1-1/4" (32 mm) connection. Operating curves are fully validated.
This borehole pump end is specified for water temperatures up to 35°C. The unit is specified for deep immersion up to 150 meters with a 4OS motor or 300 meters with an L4C motor. Horizontal operation is possible with 4OS motors up to 2.2 kW and L4C motors up to 7.5 kW. The multi-stage design requires proper coupling with standard motors to maintain correct performance under standard system heads.

How deep can the Lowara 4GS30 push water from underground?
With a maximum head of 204 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 4GS30?
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 4GS30 off a farm generator or solar inverter?
Yes, as long as your generator matches its 3.0 kW requirement. It's built for continuous duty on 415V three-phase or standard rural power setups.
Is the Lowara 4GS30 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.
