Hydraulic piston pumps are robust devices used in marine hydraulics to convert mechanical energy into hydraulic energy. They feature high-pressure capabilities and precise flow control, ideal for demanding marine applications. These pumps ensure reliable operation in steering systems, winches, and other critical marine machinery.

Key specifications and technical properties of Hydraulic Piston Pumps for Marine Hydraulics:

Size: Ranges from 10 cc/rev to 500 cc/rev, depending on application.

Grade: Typically meets ISO 4406 cleanliness standards, with pressure ratings up to 450 bar.

Viscosity: Optimal performance at 15–160 cSt, with recommended ISO VG 32, 46, or 68 hydraulic fluids.

Buoyancy: Not applicable; designed for fixed or submerged marine systems with corrosion-resistant sealing.

Material: Housing: cast iron or aluminum alloy; Pistons: hardened steel; Seals: nitrile or fluorocarbon for saltwater resistance.

Operating Temperature: -20°C to 80°C (-4°F to 176°F).

Flow Rate: 5–300 L/min, depending on pump size and speed.

Mounting: SAE or ISO flange configurations for marine engine integration.

Corrosion Resistance: Coatings or stainless steel components for saltwater environments.

Compliance: Meets DNV, ABS, or other marine classification society standards.

Yes, Hydraulic Piston Pumps and Marine Hydraulics typically comply with maritime standards such as ISO 4406, ISO 4407, and DNV GL standards, depending on the specific product and manufacturer.
