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.
