    Hot oil pumps are commonly used in systems that involve heat transfer through the circulation of thermal fluids. These fluids, often mineral oils or synthetic oils with high thermal stability, carry heat from a heat source to different components or processes within a system.


    • Corrosion Resistance. Pumps used for hot oil applications are typically made from materials that resist corrosion, ensuring the longevity of the pump in harsh operating conditions.
    • Robust Construction. Hot oil pumps are built to be robust and durable, with materials chosen to withstand the thermal stresses associated with high-temperature operations.
    • Efficiency. Hot oil pumps are engineered for high efficiency to minimize energy consumption while effectively circulating the heat transfer fluid through the system.

    Tips: How does hot oil pump work?

    A hot oil pump operates by utilizing centrifugal force to move hot oil through a system. It consists of several key components: an impeller, casing, shaft, bearings, and a motor. When the motor starts, it drives the shaft, which in turn rotates the impeller within the casing. As the impeller spins, it creates a centrifugal force that forces the hot oil into the pump's inlet. The rotation of the impeller increases the oil's velocity, creating a low-pressure zone at the center of the impeller. This low-pressure zone draws more oil into the pump, increasing the flow rate. The oil then exits the pump through the discharge outlet at a higher pressure, ready to be circulated through the system. The efficiency and effectiveness of the pump depend on factors such as impeller design, motor power, and system pressure requirements.
