Oil Pumps & Pressure Accumulators

Oil Pumps & Pressure Accumulators: Explained

When it comes to maintaining the health and performance of your vehicle, the oil system plays a crucial role. At the heart of this system are the oil pumps and pressure accumulators. These components ensure that your engine is lubricated properly, reducing friction and wear, and ultimately extending the life of your vehicle. In this guide, we will delve into the world of oil pumps and pressure accumulators, explaining their function, benefits, and why they are essential for any performance vehicle.

Understanding Oil Pumps

Oil pumps are responsible for circulating oil under pressure to the engine's moving parts. This lubrication is vital for reducing friction, dissipating heat, and preventing metal-to-metal contact that can cause severe damage. The oil pump is driven by the engine's crankshaft or camshaft, and its performance is critical for the overall health of the engine.

Types of Oil Pumps

There are primarily two types of oil pumps used in automotive engines:

  • Rotary Oil Pumps: These are the most common type of oil pumps, featuring two rotating gears that pump the oil.
  • Gerotor Oil Pumps: These pumps use an inner and outer gear with slightly different diameters to pump the oil.

Understanding Pressure Accumulators

Pressure accumulators work in tandem with oil pumps to maintain consistent oil pressure, especially during high-performance driving conditions. They store pressurized oil that can be released when the oil pressure drops, ensuring a steady supply of oil to the engine. This is particularly important during hard acceleration, cornering, or braking when oil can slosh away from the pump intake.

Benefits of Pressure Accumulators

Installing a pressure accumulator in your vehicle can offer several benefits:

  • Improved Engine Longevity: By maintaining consistent oil pressure, pressure accumulators reduce wear and tear on the engine, extending its lifespan.
  • Enhanced Performance: With a steady supply of oil, your engine can perform at its best, even under demanding driving conditions.
  • Protection During Cold Starts: Pressure accumulators can provide immediate oil pressure during cold starts, protecting your engine from damage.

Choosing the Right Oil Pumps and Pressure Accumulators

When selecting oil pumps and pressure accumulators, consider your vehicle's make, model, and engine type. Also, consider your driving style and conditions. High-performance vehicles or those frequently driven under demanding conditions may benefit from high-capacity oil pumps and pressure accumulators.


Oil pumps and pressure accumulators are vital components of your vehicle's oil system. They ensure that your engine is properly lubricated, reducing friction and wear, and enhancing performance. Whether you're a car enthusiast looking to upgrade your vehicle or simply want to ensure your car is running at its best, investing in high-quality oil pumps and pressure accumulators is a smart move.
