Centralized Circulating Lubrication Systems for Industrial Applications

High Purity Northwest builds centralized circulating lubrication systems and seal oil systems for critical industrial applications. Our systems are available in a wide range of flow rates and pressures, built using reliable, time-tested components, and can be ordered to meet API 614 5th Edition standards, with stainless steel construction options available.

What Is a Centralized Lubrication System?

A centralized lubrication system delivers a continuous, controlled flow of pressurized oil to bearings, gears, seals, and rotating components from a single centralized reservoir. Also referred to as a central lube system or circulating oil system, these systems eliminate the inconsistencies of manual greasing, reduce equipment wear, and keep machinery running without unplanned downtime. In a circulating configuration, oil is continuously pumped through the system and returned to the reservoir for cooling and filtration before re-use, making it well-suited for high-load, continuously operating equipment.

System Features and Specifications

Our centralized oil circulating lubrication systems are engineered for reliability in demanding environments. Systems are available across a wide range of flow rates and pressures and can be configured to meet API 614 5th Edition requirements for turbomachinery and rotating equipment. Stainless steel construction is available for corrosive or high-purity applications. Standard configurations include dual pump setups with an AC main pump and a DC-powered backup to ensure continuous operation, along with integrated high-efficiency filtration to deliver clean, particle-free oil. Reservoir sizing, control panel options, PLC-based monitoring, and complete documentation packages, including electrical schematics and P&IDs, are all available to suit your specific installation requirements.

Seal Oil Systems

High Purity Northwest also designs and builds complete seal oil systems for rotating equipment, including centrifugal compressors and gas turbines. Seal oil systems maintain the correct differential pressure between process gas and sealing oil to prevent gas leakage and ensure continuous, reliable operation. Systems are available with stainless steel construction and can be built to API 614 specifications for oil and gas and petrochemical environments.

Industrial Applications

Our central lube systems are used across a wide range of heavy industrial markets. In power generation and hydroelectric facilities, our systems provide bearing lubrication for turbines, generators, and auxiliary equipment. In pulp and paper mills, we supply central lubrication at forming sections, dryers, and wood yards. For oil and gas and petrochemical operations, we build API 614 lube oil consoles and seal oil systems for compressors and turbines. Our circulating oil systems are also used in steel plants and heavy manufacturing for gearbox and rolling mill lubrication, in boiler systems requiring continuous operation in high-heat environments, and in defense and military applications involving large gearboxes and mission-critical rotating equipment.

Why High Purity Northwest

High Purity Northwest has been designing and manufacturing industrial lubrication systems since 1995. Every system is engineered to your specific flow rate, pressure, and application requirements. We have supplied systems to U.S. Army Corps of Engineers facilities, defense contractors, hydroelectric dams, and industrial operations across the country. All systems ship with a complete documentation package including electrical schematics, P&IDs, and maintenance manuals.

Frequently Asked Questions

What is the difference between a centralized lubrication system and a circulating lubrication system?

A centralized lubrication system distributes lubricant from a single source to multiple points. A circulating lubrication system is a specific type of centralized system that continuously pumps oil through a circuit, returning it to the reservoir for cooling and filtration before re-use. High Purity Northwest builds complete centralized circulating systems that combine both functions.

Do your systems meet API 614 5th Edition standards?

Yes. We offer full API 614 5th Edition compliance across our circulating lube oil console and seal oil system product lines, including documentation, material requirements, and testing procedures.

What flow rates and pressures are available?

Our systems are available across a wide range of flow rates and operating pressures. Contact us with your specific requirements, and we will put together a system recommendation.

Can your systems operate in hazardous or corrosive environments?

Yes. We offer stainless steel construction options and can design systems to meet NEMA, Class I Div. 1/2, and other hazardous location classifications.

What industries do you serve?

We serve power generation, oil and gas, pulp and paper, defense, steel manufacturing, hydroelectric, and heavy industrial markets and more.
