Which pump features a cam inserted between the discharge and inlet ports?

The pump that features a cam inserted between the discharge and inlet ports is the flexible vane pump. This design utilizes flexible vanes that adapt to the contours of the cam, which helps create a seal that allows for effective fluid movement. As the cam rotates, it guides the vanes in and out, enabling the pump to draw fluid in through the inlet while pushing it out through the discharge. This mechanism is essential for maintaining a consistent flow and pressure in various applications.

The cam action of the flexible vane pump ensures smooth operation and can handle varying viscosities of liquids, making it an efficient choice in many industrial and commercial settings. The flexibility of the vanes allows them to conform to the changing cavity created by the cam, leading to better suction and discharge capabilities compared to other pump designs.

This pump design stands out due to its efficiency in transferring fluids and its ability to handle pulsating flows, which is often a result in systems where pressure fluctuations need to be managed effectively. Understanding the mechanics of how the cam and vanes work together helps in recognizing why this type of pump is suitable for specific operational requirements.
