Product Overview

The multi-stage Lowara 2GS03 is a submersible borehole wet end within the high-performance e-GS family of pump ends. The system becomes operational once coupled to a standard 0.37 kW (0.49 HP) electric motor. It allows vertical installation in narrow wells or horizontal mounting.

With a stainless steel external casing, the pump end is constructed to resist water corrosion. The internal design has 7 stages featuring floating impellers molded from PC/PPO + PS polymer. This configuration is specified for suspended sand up to 150 grams per cubic meter.

Pairing this wet end with a standard 0.37 kW electric motor rated at 3.2 Amps on a 240 V single-phase line yields a maximum head of 42.0 m. The multi-stage pump end delivers a maximum flow of 50 L/Min via its Rp 1-1/4" (32 mm) outlet. Performance is verified under standard testing.

Maximum fluid temperature for this pump end is specified for 35°C during operation. The submersion limit is 150 meters when coupled with a 4OS motor and up to 300 meters with an L4C motor. Horizontal placement is possible up to motor-rated kilowatts. The multi-stage design requires proper coupling with standard motors to maintain correct performance under standard system heads.

FEATURES

  • Equipped with 7 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.

Will sand in my bore water ruin the Lowara 2GS03?

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 2GS03 off a farm generator or solar inverter?

Yes, as long as your generator matches its 0.37 kW requirement. It is designed for continuous duty on a 240 V single-phase supply.

Is the Lowara 2GS03 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.

What pipe size connects to the Lowara 2GS03 discharge port?

It fits a standard 32 mm outlet connection. Using the right pipe diameter ensures you get the full 50 L/Min discharge flow.
