JS Series Dewatering
PDF datasheet mirror for JS Series Dewatering (JS Pump). Verify with OEM before design.
Summary
Product identification
The JS & JST series are multipurpose submersible pumps designed for various applications, including drainage of slightly waste water. They are suitable for portable use or permanent installation, with some models (e.g., JS-400A) equipped with a level controller for automatic operation.
Typical applications include:
- Dewatering of cellars, garages, basins, pools, ditches, and pits.
- Water transfer.
- Gardening and horticulture.
- Civil engineering and agriculture purposes.
Key features of the pumps include:
- Motor with built-in overload protector.
- Shaft with heat treatment for long-lasting continuous operation.
- Mechanical seals in an oil chamber with an extra external lip seal.
- Rugged and durable construction using Stainless Steel and Cast Iron.
- Potted leads, sealed with epoxy resin.
- Some models (e.g., JS400MA) offer an extra service 3-function selector switch for "MANUAL-OFF-AUTO" control.
- All pump models are available with a float switch.
A detailed parts list is available in the official PDF, outlining components such as strainer, impeller, pump housing, O-rings, lip seal, mechanical seal, motor casing, rotor shaft, stator, bearings, overload protector, condenser, cable gland, and discharge outlet.
Performance curves illustrating capacity (L/min) for various JS and JST models are provided in the official PDF.
Operating limits
The JST series pumps are specified for operation at either 50 or 60 Hz.
