Onga SSS3703 2.20kW Stainless Steel Low Noise Single Phase Centrifugal Pump for Potable Water

The Onga SSS3703 is a premium-quality stainless steel centrifugal pump, engineered for agricultural, commercial, and industrial applications where reliability, corrosion resistance, and quiet operation are paramount. Built to Pentair’s high performance and efficiency standards, the SSS3703 delivers up to 520 litres per minute at a maximum head of 23.4 metres, making it ideal for potable water transfer, irrigation, wash down, and mild chemical handling.

Constructed entirely from 304-grade stainless steel for all wetted components—including the pump casing, impeller, and motor shaft—the SSS3703 ensures long service life even in demanding environments. The TEFC 2-pole motor, NSK bearings, and high-quality mechanical seal (silicon carbide/graphite with 304SS spring) provide robust, low-maintenance operation. The pump is continuously rated and designed for easy installation and operation, with a maximum liquid temperature of 85°C and a maximum working pressure of 10 bar.
