Functioning as an automated heavy duty, submersible stainless steel grey water pump, the Grundfos UNILIFT AP12.40.04.A1 provides consistent fluid management. It is tailored for handling clean water, storm water, and slightly dirty wastewater across domestic and light industrial sites. The unit features an integrated float switch for hands-free operation, making it ideal for permanent sump installations or portable temporary drainage tasks.
The internal mechanics forcefully push liquids out of a 40 mm female connection, maintaining a maximum flow of 233 L/Min. When pumping against vertical gradients, the unit reliably achieves a 10 metre maximum head. This hydraulic displacement relies on an optimized 0.4 kW motor core. Running directly on a 1 x 240 V single-phase grid, the automated system draws a rated 3 Amps under load to maintain stable rotational torque.
Managing cloudy environmental run-off necessitates a wide internal tolerance for debris. A heavily balanced semi-open stainless steel impeller controls the main fluid vortex, allowing solid matter up to 12 mm to transit safely through the volute. This strategic clearance limits abrasive wear against the central shaft while maintaining the ability to drain standing pools down to a 100 mm minimum clearance level.
Complete environmental sealing ensures an IP68 classification, protecting the motor down to a 7-metre underwater depth. An intelligent cooling jacket surrounds the drive, regulating core thermals to facilitate continuous pumping during partial fluid exposure. The pump effortlessly manages 55°C liquids, briefly tolerates 70°C for two-minute intervals, and withstands ambient fluids between pH 4 and 10.
FEATURES
- Features a heavy-duty brass cable union to strictly isolate the primary electrical feed from ambient moisture intrusion.
- Rated with an internal Class F insulation threshold to safely tolerate heavy electrical load fluctuations.
- Utilizes a Permanent Split Capacitor (PSC) motor architecture to ensure smooth rotational startup sequences.
- Equipped with internal thermal protection circuitry that acts as an immediate safety cutoff to prevent coil burnout.
- Pre-installed with a 10-metre power supply cable terminating in a standard single-phase plug for immediate deployment.
- Certified with C-Tick and CE compliance markings to guarantee strict adherence to recognized environmental standards.
- Unit possesses a net weight of 10.7 kg, allowing for secure positioning when lowered into active drainage sumps.
