Product Overview
Specified as a standalone hydraulic pump end, the Lowara 2GS30 belongs to the e-GS series for deep well extraction. Pairing with a compatible 3.0 kW (4.0 HP) motor is necessary for system operation. Standard vertical casing installation is standard, but horizontal mounting is specified within motor limits.
Constructed with a stainless steel casing, the pump end protects internal hydraulic components from rust. The multi-stage assembly incorporates 52 floating impellers made of PC/PPO + PS polymer. It permits continuous handling of sand in water up to 150 grams per cubic meter.
Pairing this pump end with its required 3.0 kW motor (7.1 Amps current on 415 V three-phase supply) enables a maximum head of 309.0 m. The coupled system produces a maximum flow of 50 L/Min discharging through a 32 mm Rp outlet. Performance curves conform to factory specifications.
During continuous operation, the wet end handles fluid temperatures up to 35°C. Operating depth limits are 150 meters with 4OS motors and up to 300 meters with L4C motors. Horizontal mounting 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.
FEATURES
- Equipped with 52 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.

What is the rated vertical lifting elevation for this borehole submersible assembly?
Across demanding borehole depths, the 2GS30 develops a maximum dynamic head of approximately 309.0 m to ensure strong surface water delivery.
What discharge pipe diameter attaches to the pump and what peak delivery rate is attained?
Delivery pipe connection is made via the 32 mm (Rp 1-1/4") threaded head, where the 2GS-30 discharges up to a peak flow rate of approximately 50 L/Min inside standard 4-inch (100 mm) or larger borehole casings.
What grade of corrosion resistance does this submersible bore pump offer underground?
Mineral resistance in deep water extraction is maintained through stainless-steel with floating impellers, with the 2 GS 30 managing suspended sand up to 150 g/m³.
Which electrical power rating and voltage supply are specified for this bore pump?
Electrical demands for the 2_GS_30 wet end specify a 3.0 kW motor connected to 220–240 V, 50 Hz, single-phase (while also supporting 380–415 V, 50 Hz, three-phase motors).
Does this submersible bore pump include a check valve and allow horizontal configurations?
To protect against reverse flow, the 2GS30 includes an integrated stainless-steel non-return valve in the discharge head, while horizontal mounting is supported at a minimum recommended 3° incline with the motor lowest and a cooling sleeve.
