SWJ1

The SWJ1 represents Crompton's premium engineering in the shallow-well jet pump (SWJ series) category, delivering reliable water-handling performance for shallow suction (up to 8 metres). Best deployed in shallow water sources up to 8 metres suction depth, agricultural use, small farm irrigation, and rural water supply. Classified as shallow well self-priming duty, it shallow tube wells and surface water sources without deep submersible requirement.

Technical specifications:

• Rated power: 1 HP / 0.75 kW
• Power supply: single-phase 230V, 50 Hz
• Delivery pipe size: 50 mm
• Number of stages: 1 (multi-stage impeller for sustained head)
• ISI / BIS certified: Conforms to Indian Standards (IS 8034 / IS 9079 / IS 14220 as applicable)
• Motor protection: IP55-equivalent for submersible variants; thermal overload protection on terminal box
• Construction: Stainless steel sleeves, brass impellers (or thermoplastic for corrosive water), and cast-iron motor body where applicable

The SWJ1 is engineered for surface-mounted with jet assembly for high suction efficiency. The single-stage hydraulic profile is optimised for the application — high efficiency at the design duty point with smooth flow characteristics. ISI/BIS certification means the pump has passed independent testing for hydraulic performance, electrical safety, and minimum efficiency thresholds mandated by Indian Standards. For Shallow-well jet pump (SWJ series)s of this rating, installation typically requires properly sized cabling, an appropriate control panel with dry-run protection, and correct earthing as per IS 3043.
