The Onga 121 is a molded technopolymer self-priming centrifugal pump configured for septic tank dewatering; sump emptying; and grey water transfer. Its open impeller design allows it to pump liquids containing soft suspended solids without clogging.
Operating on a single-phase 240v power supply; the 1.1 kW motor draws a nominal current of 10.8 Amps. The pump delivers water flows up to 213 L/Min and achieves a maximum head of 15 m.
It features a highly corrosion-resistant pump casing manufactured from 20 percent glass-filled ABS. A built-in check valve provides excellent self-priming characteristics and prevents fluid backflow.
The mechanical design incorporates an integrated thermal overload to protect the motor from overheating. Port dimensions are a 40 mm BSP male inlet and a 32 mm BSP male outlet for easy hose connection.
