Oil Pumps & Pressure Accumulators

Oil pumps and pressure accumulators are critical components in the lubrication systems of motorsport vehicles, designed to ensure consistent oil flow and pressure under extreme conditions. Oil pumps, typically gear or rotor type, are constructed from high-strength materials such as billet aluminium or steel to withstand high RPMs and the intense demands of racing. These pumps are engineered for precise oil delivery, maintaining optimal lubrication and cooling for the engine's moving parts.

The primary function of an oil pump is to circulate oil from the sump throughout the engine. High-performance oil pumps feature advanced designs that provide a high flow rate and stable pressure, even at elevated engine speeds. The pump’s efficiency in moving large volumes of oil is crucial for maintaining the thin oil film that protects engine components from friction and wear, ensuring reliability and performance.

Pressure accumulators complement oil pumps by providing an additional reservoir of pressurised oil. These accumulators are often made from lightweight, durable materials such as aluminium or carbon fibre. Inside, a piston or bladder separates the oil from a compressed gas charge, usually nitrogen. When the engine's oil pressure drops, the accumulator releases its stored oil, maintaining consistent pressure and flow, which is essential during rapid acceleration, cornering, or braking when oil slosh can momentarily starve the pump.

The integration of oil pumps and pressure accumulators ensures that the engine maintains a continuous and stable supply of oil, preventing critical engine components from experiencing lubrication starvation. This is vital for high-performance motorsport applications where any loss of oil pressure can lead to catastrophic engine failure. The combination of robust construction, precise engineering, and advanced materials makes these components indispensable for maintaining engine reliability and performance in racing environments.
