AquaForce® asynchronous, solids-handling waterfall and filter pumps combine energy-efficient performance, high flow rates, and ease of maintenance, making this pump the ideal choice for discerning pond owners. The AquaForce protective pre-filter cage allows the pump to be placed directly into the pond. AquaForce pumps are able to pump solids up to .25" inches in diameter, making them ideal for use with external pressure filters or Aquascape waterfall filter systems. The asynchronous motor technology provides high torque, trouble-free performance, and is easy to maintain. The AquaForce can also be used as a de-icer pump during cold weather months.
