Product Overview
The Lowara 8GS22 represents a high-efficiency hydraulic pump end within the redesigned e-GS borehole family. Safe operation requires coupling this wet end with a standard 2.2 kW (2.93 HP) motor. Mounting configurations allow vertical deep wells or horizontal mounting inside cisterns.
Featuring a corrosion-resistant stainless steel external casing, this pump end houses a multi-stage hydraulic stack. The system utilizes 15 floating impellers made of PC/PPO + PS polymer. This configuration handles suspended sand up to 150 grams per cubic meter of fluid.
Coupled to a compatible 2.2 kW electric motor drawing 14.4 Amps on 240 V single-phase power, the system delivers a maximum head of 81.2 m. This multi-stage pump end has a maximum flow of 183 L/Min with a 50 mm Rp connection. Performance curves match manufacturer specifications.
The pump end handles water temperatures up to 35°C. Safe immersion depths reach up to 150 meters when using a 4OS motor or up to 300 meters with an L4C motor. Horizontal installation is possible for 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 15 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.

How does this submersible pump resist harsh borehole minerals and suspended abrasive grit?
Underground mineral resistance is assured by stainless steel external casing with floating impellers made of PC/PPO + PS polymer construction in the 8GS22, which tolerates abrasive sand particulates up to 150 g/m³.
Which electrical power source and supply voltage are necessary for this borehole pump?
Driving the 8GS-22 wet end demands a 2.2 kW motor powered by 220–240 V, 50 Hz, single-phase at 14.4 A (with 380–415 V, 50 Hz, three-phase motor support also available).
Does this borehole pump have a built-in check valve and can it operate on an incline?
Backflow prevention is managed by an integrated stainless-steel non-return valve in the 8 GS 22 discharge head, and horizontal mounting is supported at a minimum recommended 3° incline with the motor at the lowest position.
What is the maximum vertical lift rating supported by this borehole pumping unit?
Operating across challenging underground depths, the 8_GS_22 develops a maximum dynamic head rating of approximately 81.2 m to overcome tall vertical risers and pipe friction.
What diameter pipe fits the top delivery port and how much water volume does it discharge?
Fitted with a heavy-duty 50 mm (Rp 2") discharge connection, the 8GS22 produces a maximum delivery capacity of approximately 183 L/Min for installations in standard 4-inch (100 mm) or larger borehole casings.
