Boat hydraulic pumps are essential for operating steering, stabilizers, and other marine systems efficiently. Marine pumps handle bilge, ballast, and freshwater transfer to ensure vessel safety and functionality. Both types are designed to withstand harsh saltwater environments for reliable performance.

Boat Hydraulic Pump:
Size: Typically 1.5" to 4" inlet/outlet
Grade: Marine-grade hydraulic fluid (ISO VG 32 or VG 46)
Viscosity: 32-46 cSt at 40°C
Buoyancy: Not applicable (fixed installation)
Material: Cast iron, stainless steel, or bronze
Pressure Range: 1500-3000 PSI
Flow Rate: 5-30 GPM

Marine Pumps (General):
Size: 0.5" to 6" inlet/outlet
Grade: Corrosion-resistant marine-grade
Viscosity: Varies by type (10-150 cSt for water, 30-100 cSt for fuel/oil)
Buoyancy: Optional for bilge pumps (self-priming)
Material: Bronze, stainless steel, or reinforced thermoplastics
Pressure Range: 10-100 PSI (varies by application)
Flow Rate: 10-500 GPM (depending on type)
