Oase 45424 Waterfall Pump 1/2 HP 120V 23 ft Head equipment

SKU CH-25CW-YZMBR

Delivers up to 5,000 GPH at 1 ft head with a 23 ft max head, energy-efficient 1/2 HP synchronous motor and quiet operation

  • Delivers 5,000 GPH at 1 ft head for strong waterfall flow
  • Reaches 23 ft maximum head height for elevated installations
  • Energy-efficient synchronous motor runs continuously at 2.5 A full load
  • Quiet operation with grounding plate for safe, low-noise performance
  • 20 ft power cord allows flexible placement away from outlets

Waterfall Pump for Vertical Installation

The Oase 45424 is a 1/2 hp waterfall pump designed for vertical installation in pond or waterfall systems. It operates on 120V AC at 60 Hz with a synchronous motor and includes a 20 ft power cord. The unit features an energy-efficient motor, grounding plate, and quiet operation for continuous duty use.

Flow Rates Across Head Heights

This pump delivers 5,000 GPH at 1 ft of head, 4,320 GPH at 5 ft, 3,580 GPH at 10 ft, and 350 GPH at 20 ft, with a maximum head of 23 ft. It handles solids up to 1/6 in through an ABS impeller and draws 2.5 A at full load. The compact dimensions allow placement in confined vaults or skimmer boxes.

Sustained Continuous Duty Performance

Built for continuous duty, the synchronous motor maintains steady flow over long periods without thermal cycling interruptions. The energy-efficient design keeps power draw stable at 2.5 A during extended operation. It is not suited for applications requiring higher head pressure or solids handling beyond 1/6 in.
