Product Overview
Materials of construction for this unit include a cast iron pump body and motor frame with 304 stainless steel fasteners. The AISI 403 stainless steel shaft is protected by a double mechanical seal in an oil chamber featuring Silicon Carbide lower faces. Electrical safety is supported by Class F insulation and an IP68 protection rating for the air-filled dry motor.
The semi-vortex impeller is designed for non-clog operation when handling wastewater containing soft or fibrous solids. This hydraulic path allows the passage of foreign matter up to 32 mm in diameter and fibers between 150 mm and 250 mm. A 50 mm vertical delivery port is provided, including a screwed companion flange discharge elbow kit.
Performance for this 0.4 kW unit reaches flow rates of 250 L/Min and a total head of 8.8 m. Operating on a single-phase 240v supply, it draws a rated current of 1.9 Amps and includes 6 m of submersible cable. This automatic version utilizes an integrated control device and float switches for unattended start and stop cycles based on water level.
Automatic septic effluent pumping and domestic wastewater lifting are the primary applications for this vertical submerged pump. It is rated for liquid temperatures up to 40°C and maximum submergence depths of 4 meters. The system is engineered for collection pits where automated drainage cycles are required for municipal waste transfer.
