A Quality & Eartheco Pump Diffuser is a component of a pool or spa pump, typically made of a durable plastic, that helps to evenly distribute the water flow inside the pump. The diffuser is specifically designed to fit .45kW, .6kW, .75kW, and 1.1kW pumps. The diffuser is located inside the pump and is responsible for directing the water flow to the impeller. This can help to improve the efficiency and performance of the pump. The Quality & Eartheco brand is known for making high-quality pool and spa equipment, and the diffuser is no exception. It is a replacement part that can be used to fix a malfunctioning or damaged diffuser and help to prolong the life of the pump.
