Paguro 8500 Generator 400V 8.5 kVA 8 kW (50 Hz) 1800 RPM

Description

Power commercial boat three-phase distribution switchboards with the Paguro 8500 Three-Phase Marine Generator. Operating at 1,500 RPM, this three-cylinder 1.028-liter diesel auxiliary engine produces 8.0 kW continuous three-phase power with 8.5 kVA peak capacity at 400 volts. Freshwater heat exchanger cooling isolates raw seawater from inner cast iron coolant channels, sustaining commercial refrigeration, watermakers, and workshop machinery without line voltage droop.

A thick-wall cast iron cylinder block absorbs high internal combustion pressures during sustained offshore duty cycles. The reciprocating crank group combines a heat-treated forged alloy steel crankshaft, forged connecting rods, and oil-cooled aluminum alloy pistons. Engineering specifications include a 72 mm bore, 84 mm stroke, 22.8:1 compression ratio, 3.0-quart oil sump capacity, and dry weight of 418 lbs inside its acoustic capsule. Heavy webbing prevents case distortion.

Key Features of Paguro 8500

Commercial mariners buy Paguro 8500 generator packages to achieve dependable three-phase power inside working vessel hulls. This 50 Hz power unit outputs balanced 400-volt alternating current to eliminate phase imbalances across heavy machinery spaces.

• 8.0 kW continuous 400-volt three-phase output supports heavy induction motor starts without voltage sag.
• Four-pole brushless alternator design uses solid-state regulation to hold line voltage variation within one percent.
• Heavy sound attenuation housing suppresses internal combustion noise down to 52 decibels at seven meters distance.
• Paguro 8500 marine generator digital control unit tracks oil pressure, coolant heat, and engine rotation speed.
• Cupronickel tube-and-shell heat exchanger shields internal cast iron block passages from direct raw seawater contact.
• Automatic protection logic triggers instant engine shutdown upon loss of water flow, low oil, or overspeed.
• Starboard service access concentrates dipsticks, fluid filters, and the sea water pump behind one panel.

Three Phase Alternator Output Verification

Turning at a governed 1,500 RPM, this four-stroke diesel delivers clean 50 Hz electrical power across marine switchboards. Continuous three-phase output yields 8.0 kW (8.5 kVA at 0.8 power factor) across 400-volt circuits. Measured fuel burn records 0.55 gallons per hour at half load and 0.98 gallons per hour at full continuous rating. Pressurized internal lubrication galleries sustain 35 to 55 PSI hot oil pressure, shielding critical crankshaft and camshaft journals from friction during non-stop offshore commercial operations.

Sound Shield Hull Clearance Boundaries

The sound shield capsule measures 770 mm long, 460 mm wide, and 560 mm high, dropping between structural inboard stringers. Four captive rubber isolators prevent mechanical vibration transmission to hull frames. A 2-inch water-cooled wet exhaust mixer drops cooled gases overboard, requiring five inches of starboard clearance for technician access.

Diesel Generator Service Maintenance Rules

Purge air from fuel injection passages using the manual primer arm before engaging the electric starter. Fill freshwater cooling loops with approved marine coolant to prevent localized hot spots. This unit is not engineered for dry land exhaust operation, raw sea water block circulation, or unventilated bilge spaces.

• Drain factory break-in lube oil and install fresh filter elements after the first 50 operating hours.
• Inspect flexible raw water pump impellers and drain fuel sediment bowls every 200 running hours.
• Clean cupronickel heat exchanger tubes and replace sacrificial zinc anode plugs every 12 months.

Marine Warranty Pack Manifest

Paguro supports this generator with a 24-Month limited commercial marine warranty. The wooden freight crate contains the complete generator unit, sound attenuation enclosure, remote digital control panel, flexible fuel line kit, factory load test printout, and technical operator service documentation binder.
