Product Overview

Reliable domestic water supply and light commercial distribution benefit from the Lowara 6GS11-12L, a 2-wire submersible bore pump with an internal capacitor. This 4-inch unit removes the need for an external control panel while delivering efficient fluid transfer. The floating impeller design supports performance in water containing suspended solids.

A 1.1 kW single-phase motor on 240 V draws 7.6 Amps during normal operation. Maximum flow reaches 140 L/Min, while maximum head extends to 51.8 metres at shut-off. The motor requires a minimum fluid velocity of 8 cm/s around the casing for adequate 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.

Features

  • Two-wire motor design with built-in capacitor simplifies electrical installation
  • Floating impeller system handles abrasive groundwater without performance loss
  • Hexagonal stainless steel shaft provides effective drive across all pump stages
  • Front wear ring improves resistance to abrasive wear in sandy conditions
  • Integrated non-return valve prevents reverse flow on motor shutdown
  • AISI 304 stainless steel construction offers corrosion resistance during submersion
  • Supplied with heatshrink kit for waterproof electrical connections
