Product Overview
Structural features include a 304 stainless steel pump casing, motor frame, and impeller for resistance to corrosion in submerged dewatering duties. Sealing is managed by a mechanical seal in an oil-lubricated chamber featuring Ceramic/Carbon/NBR faces, supported by an upper lip seal. The rotating assembly is carried by a 303 stainless steel shaft and sealed ball bearings, ensuring mechanical stability during transportable or fixed service.
Dewatering of basements and the general transfer of clean water are the documented applications for this manual submerged pump. It is rated for liquid temperatures up to 50°C and a maximum submergence depth of 5 meters. The manual configuration is designed for installations where discharge cycles are managed by an external control panel or for portable tasks requiring manual operation.
The hydraulic system utilizes a semi-open centrifugal impeller designed for the movement of clean liquids containing suspended solids up to 10 mm. This design permits the passage of suspended solids through a 32 mm discharge port without risk of blockage. For specialized tasks, this manual unit can be equipped with a low-level suction skirt to facilitate the drainage of flat surfaces down to a 3 mm water depth.
Operating with a 0.25 kW motor, this manual single-phase unit reaches flow rates of up to 170 L/Min and a total head of up to 8.3 m. It draws a rated current of 2.3 Amps on a 240v supply and is protected by a 5 m submersible power cable. The air-filled 2-pole induction motor includes in-built thermal protection to safeguard the winding from damage during high-load drainage tasks.
FEATURES
- Manual configuration supports integration with external pump switchgear and control panels.
- Optional low-level suction skirt enables drainage down to 3 mm water depth on flat surfaces.
- Ceramic/Carbon/NBR mechanical seal faces provide reliable sealing in clean water service.
- Upper NBR lip seal offers additional protection against moisture at the motor side.
