Fast priming and steady flow - with self-priming diaphragm design
Self-priming capability reaches up to 10ft vertical lift and 155ft horizontal suction, while a one-piece four-chamber diaphragm sustains the rated 6 GPM flow. Diaphragm layout balances pulses for continuous output.
Quickly draws from tanks and sustains flow for multiple outlets during typical RV or marine use. Suits filling, hand-washing and light-duty showering without frequent interruption.
Quiet, durable operation - with NSK double ball bearings and 4-chamber diaphragm
NSK double ball bearings reduce mechanical friction and the four-chamber diaphragm evens load distribution to lower vibration and noise. Construction uses high-quality components and 1/2 NPT pipe thread for robust plumbing connections.
Low-noise behaviour works well for night-time and confined environments aboard caravans and yachts. A three-year factory warranty supports longer-term reliability and peace of mind.
