Quiet and pulsation-free even at low speeds, the new Aqua Jet five-chamber diaphragm pump provides the perfect water pressure solution for both small and medium sized leisure and commercial boats.
Compared to three- and four-chamber diaphragm pumps, the five-chamber Aqua Jet demonstrates dramatically lower noise and water pulsation characteristics.
Johnson recommends installing an accumulator tank in water pressure systems.
Always, use a Johnson PUMProtector inlet strainer before the pump intake.
