Salient Features

All wetted hydraulic parts in SS 304 (SS 316 optional)
Stamped & laser-welded construction — no castings in wetted path
Polished surface for low friction and easy cleaning
Sand-resistant impellers with floating clearance
Built-in non-return valve at discharge
Submersible motor with hermetic seal and SS body
Suitable for potable water (NSF-compliant materials available)
Lightweight design — typically 20–30% lighter than CI equivalents
Designed for water with chloride content up to 250 ppm (SS 316: higher)

Applications

Coastal & saline groundwater pumping
Mineral-rich / hard water sources
Reverse osmosis (RO) feed pumping
Solar pumping in remote areas
Food, pharma, & potable water supply
Domestic & municipal supply where corrosion is a concern
Light chemical / process water transfer (compatibility-dependent)

Specify chloride / TDS content, pH, and free CO₂ for correct grade selection (SS 304 vs SS 316 vs duplex).

For potable water duty, request NSF / WRAS material certification at RFQ stage.
