Onga SPN100S Cast Iron High-Head Centrifugal Pump for Domestic Water Transfer with Twin Impeller

Clean water transfer across domestic, civil, and industrial applications is the primary service duty for this rugged centrifugal pump. It is designed for pumping clean water where controlled transfer tasks are required. The unit is suitable for washdown, heating and cooling systems, agriculture, and horticulture.

Hydraulic performance includes a maximum head of 47 m and a maximum flow rate of 100 L/Min. The 1.1 kW single-phase motor operates on a 240v supply and draws a full load current of 7 Amps. The twin impeller design enables the pump to handle medium to high flow rates while maintaining significant pressure for varied water distribution tasks.

The hydraulic system utilizes high efficiency twin brass impellers to build pressure through two centrifugal stages. This configuration maximizes pressure output relative to the pump's footprint while ensuring quiet operation. The unit is designed to handle clean liquid temperatures ranging from 0°C to +90°C, making it versatile for temperate water transfer requirements.

Construction features a rugged cast iron pump casing for structural durability and brass impellers for mechanical stability. Sealing is managed by a high-quality mechanical shaft seal featuring a Ceramic/Graphite/NBR arrangement. The TEFC motor is rated at IP44 and operates at a nominal speed of 2900rpm, ensuring reliable 50Hz service in ambient temperatures up to 40°C.
