Product Overview
Agricultural networks and residential sprinkler irrigation depend on the Lowara 2GS05-12L, a 2-wire submersible bore pump with built-in capacitor technology. This 4-inch unit removes the necessity for a surface control box while handling continuous groundwater extraction. The floating impeller configuration supports performance in water containing suspended solids.
A 0.55 kW single-phase motor on 240 V draws 4.3 Amps during normal operation. Maximum flow reaches 50 L/Min, while maximum head extends to 60 metres at shut-off. The motor requires a minimum fluid velocity of 8 cm/s around the casing for effective cooling, and supports up to 30 starts per hour.
Inside the hydraulic section, floating impellers allow suspended particles up to 150 g/m³ to pass without compromising internal clearances. The hexagonal pump shaft delivers torque reliably across all stages, while the front wear ring works with the floating impeller to improve abrasion resistance. An integrated stainless steel check valve prevents destructive backflow when the motor stops.
Precision-cast stainless steel upper and lower support brackets maintain alignment between the pump and motor. The 99 mm diameter casing fits standard 4-inch boreholes, with a 32 mm threaded outlet. Rated for continuous immersion in liquids up to 35°C, the complete unit comes with a heatshrink kit for secure electrical connections.

What is the maximum lift height of this 2-wire agricultural irrigation pump?
The 2GS05-12L reaches a maximum shut-off head of 60 metres with a flow rate up to 50 L/Min.
How does this deep-well pump protect against abrasive sand wear?
The front wear ring works alongside the floating impellers in the 2GS-05-12L to improve abrasion resistance in sandy groundwater.
Does this model require an external starting control box?
The 2GS 05 12L eliminates external starting boxes thanks to its 2-wire motor design with an internal capacitor.
What is the electrical current draw of this 0.55 kW single-phase motor?
Operating on a 240 V single-phase connection, the 0.55 kW motor of the 2GS_05_12L draws 4.3 Amps.
What minimum water flow velocity is required around the casing to cool the motor?
A minimum fluid velocity of 8 cm/s circulating past the casing is required to ensure adequate cooling for the 2GS05-12L.
