Disc Centrifugal Oil Purifier 1500LPH Marine Fuel Oil Lube Oil Water Separation System

1500L/H CPPA Disc Centrifugal Oil Purifier — High-Efficiency Liquid-Liquid-Solid Separation

Product Description

Sino-NSH-CP series is a disc-type centrifugal oil purification system combining thermal conditioning, precision filtration, and high-speed centrifugal separation. Available in capacities from 1500 L/H to 6000 L/H, this series is purpose-built for the marine and power generation industries to remove water, solid particles, and oxidation byproducts from fuel oil, lubricating oil, and other mineral oils.

The CPPA model features partial-auto discharge — sludge is ejected automatically at preset intervals, while the clean oil and separated water exit through independent outlets. This reduces operator intervention and ensures consistent purification output during extended engine room or power station operation. Additionally, the separator can process two immiscible liquids with different specific gravities, making it suitable for bilge water treatment and waste oil recovery applications.

How Disc Centrifugal Separation Works

The CP series employs a high-speed rotating bowl (7,200 RPM typical) containing a stack of conical discs. As contaminated oil enters the bowl, centrifugal force exceeding 8,000 G causes:

- Water (higher specific gravity) to migrate outward toward the bowl periphery and exit through a separate water discharge port.
- Solid particles to accumulate on the inner bowl wall as sludge, automatically ejected at programmed intervals.
- Clean oil (lowest specific gravity) to flow inward through the disc stack and exit through the centripetal pump at the bowl center.

This three-phase separation (oil-water-solids) occurs continuously during operation without filter element replacement, unlike conventional media-based filtration systems.

Key Features

- High-speed disc bowl assembly: 7,200 RPM bowl rotation generating over 8,000 G centrifugal force, achieving separation of water and solids down to 1–3 μm particle size in a single pass.
- Auto-sludge discharge (CPPA model): Programmable partial-discharge cycle ejects accumulated sludge at configurable intervals without interrupting oil flow — supporting 24/7 unattended operation.
- Integrated heating system: Oil pre-heating to 60–95°C reduces viscosity, improving water separation efficiency particularly for heavy fuel oil (HFO) with viscosity up to 380 cSt at 50°C.
- Independent clean oil discharge: Built-in centripetal pump delivers purified oil at discharge pressure up to 0.2 MPa, eliminating the need for a separate delivery pump downstream.
- Vibration-monitored operation: Bowl vibration maintained below 2.5 mm/s (ISO 10816-3 compliant), with automatic shutdown triggered at 4.5 mm/s for bearing and gear protection.
- Stainless steel bowl and disc stack: AISI 316L material construction provides corrosion resistance against saltwater exposure and acidic oil contaminants in marine environments.

Typical Applications

- Marine engine rooms: Continuous purification of heavy fuel oil (HFO) and marine diesel oil (MDO) for main propulsion engines and auxiliary generator sets.
- Coastal and offshore power stations: Lube oil conditioning for medium-speed diesel generators operating on residual fuels.
- Industrial lubricant recovery: Water and particulate removal from used hydraulic oil, gear oil, and turbine lubricating oil.
- Bilge water treatment: Oil-water separation for marine environmental compliance (MARPOL Annex I).
