Sliding Vane Pumps
Sliding vane pumps are rotating pumps with vanes that slide in and out of the rotor slots to form volumetric chambers on both sides of the vane. They are incredibly efficient and deliver high volumes of flow and pressure. Sliding vane pumps have a wide range of applications, including oil, diesel and marine fuels, lube oil, coolants and hydraulic fluid. Because they are highly efficient, they are often used in high-pressure hydraulic applications.
Sliding vane pumps are sometimes referred to as positive displacement pumps, as they have the ability to move a set volume of fluid with each rotation. They are designed with curved plates called vanes, which move into and out of rotor slots, creating chambers. These chambers capture, contain and discharge their pre-determined volume of fluid with each rotation.
Sliding vane pumps come in several different types and are available in a variety of sizes. The most common types of sliding vane pumps are internal gear, external gear and lobe pumps. Internal gear pumps are typically used for low-viscosity liquids, such as light liquids and alcohols, while external gear pumps are suitable for higher viscous liquids, such as oils and fuels. Lobe pumps are good for thick or high viscosity liquids, such as chocolate and honey.
Sliding vane pumps are often used in applications where reliability is important. These pumps tend to operate smoothly and quietly and have a high level of reliability due to their simple design. They also have a lower required NPSH ( Net Positive Suction Head) than other pump types and can handle a wide range of flow rates, making them suitable for a wide range of applications. Additionally, they require less maintenance and are less susceptible to damage due to corrosion, wear and tear or other factors.
Sliding vane pumps have a number of advantages, including their high efficiency. They are also capable of handling higher pressures than other types of pumps, and their simple design means fewer moving parts, resulting in fewer maintenance and repair costs.
Despite their advantages, sliding vane pumps have their drawbacks as well. They tend to suffer from low suction pressure. Additionally, they are not suitable for applications where solids are present, and their relatively simple design means that they are not suitable for applications requiring more sophisticated features and components.
In conclusion, sliding vane pumps are highly efficient and reliable pumps that are ideal for a wide range of applications. They are cost-effective and require minimal maintenance, making them a great choice for many industries. Despite their drawbacks, they are an excellent option when reliability and efficiency are the primary goal.
