Onboard fresh-water boost and self-prime, without brushes.

What the onboard system actually needs

Coach and yacht loops are tank-fed, not mains-fed. The pump has to self-prime, hold pressure, and run on the electrical rail the boat or vehicle already has. Model 1 of the PEILI driver takes DC 24 V / 36 V. Models 2 and 3 take AC 115 V / 230 V and can provide a 24/36 V auxiliary output for neighbouring loads. Speed can be trimmed so shower and galley do not share one fixed winding.

• Published use: compact boost and self-prime for onboard fresh-water systems.
• DC 24 V / 36 V bus kit, or AC 115 V / 230 V kits.
• Outlet max 150 psi; flow 2.5–7.5 L/min at 100 psi.
• No carbon-brush dust in a closed cabin; no commutator spark.

Factory tests

Onboard valves still slam. The wet end is burst-tested at 3.5 MPa and water-hammer tested at 1.2 MPa for 120,000 cycles in Jiangmen. Working pressure on the nameplate stays 150 psi max.

• Type-test burst: passed 3.5 MPa (~35 bar / 508 psi). That is not the working pressure.
• Water hammer: 1.2 MPa for 120,000 cycles, then leak, flow and pressure re-checked.
• Life / endurance run under load on the Jiangmen comprehensive stand.
• Every serial unit still goes through nine outgoing benches: air tightness, mechanical properties, flame retardance, flow, noise, pressure, load, hot/cold, material reliability.
