5 Awesome Benefits of Sliding Vane Pumps

Vane pumps are a type of positive displacement pump that uses vanes to move fluids that slide in and out of rotor slots. The action generates suction, which pumps fluids. The rotor is close to the cam's wall, forming a crescent-shaped cavity on the other side. The vane pump's blades, which are always in contact with the cam wall, rotate with the rotor. The vanes slide out of the cavity as the rotor spins, trapping fluid. When the vanes reach the end of the open space, they slide back in, and the trapped fluid flows to the discharge or outlet valve.

Each pump serves a different purpose, such as internal gear pumps, external gear pumps, rotary lobe pumps, and so on, and it's critical to review which pump is best for your specific needs. An eccentric ring and a rotor with slots that house the vanes, which can move radially as the rotor rotates in the ring, make up sliding vane pumps. As the vanes revolve past the suction port, they move outward, defining a volume defined by consecutive vanes, the rotor, and the ring wall. This volume draws fluid in and seals it off as it moves past the suction port, and the eccentricity of the ring and rotor pushes the vanes into the slots, reducing volume and forcing fluid out through a discharge port.

Sliding vane pumps have a simple design and the efficient performance needed for high-volume liquid transfer in a variety of chemical processing applications. Here are the five awesome benefits of sliding vane pumps: 

Self-Priming: Sliding vane pumps are self-priming, giving them an advantage over many other pumps that require expensive priming systems to function.

1. Self-Adjusting: During operation, the unique sliding vane technology self-adjusts for wear, allowing the user to maintain consistent flow rates.

2. Dependable Performance: Sliding vane pump technology is a straightforward but elegant fluid transfer solution that offers trouble-free operation, long-term performance, and consistent results.

3. Low Maintenance: Sliding vane pumps are easy to maintain and replace without having to remove the pump from the piping system.

4. Energy-Efficient: Sliding vane pumps require significantly less horsepower than other types of pumps, allowing you to run more efficiently, save money on energy, and extend the life of your drive motors.

Difference between Centrifugal Pump and Positive Displacement Pump

The two most common types of pumps are centrifugal and positive displacement. The primary function of both types of pumps is to move fluid from one location to another. They do, however, differ in some ways. Both of these pump groups operate on different principles. The rotating impeller of a centrifugal pump transfers the kinetic energy of the motor to the liquid. The velocity and pressure at the discharge increase as a result. When the motor rpm is constant, the discharge velocity remains constant. Positive displacement pumps, on the other hand, trap a fixed volume of fluid in their cavity and force it to discharge into the pump outlet. As a result, it is a constant volume device. Positive displacement is available in rotary, reciprocating, and diaphragm configurations.

Positive displacement pumps are low-capacity, high-head pumps, whereas centrifugal pumps are high-capacity, low-head pumps. Both types of pumps have a variety of advantages and applications. However, selecting the incorrect pump may result in process failure and a low return on investment.

Here are the differences between centrifugal pump and positive displacement pump: 

1. Fluid handling: The efficiency of a centrifugal pump decreases as the fluid viscosity increases due to frictional losses. As a result, centrifugal pumps are ineffective for highly viscous fluids. Conversely, as viscosity increases, so does the efficiency of a positive displacement pump.

2. Pump speed and shearing of liquid: Centrifugal pumps operate at high speeds. It causes liquids to shear. As a result, it is unsuitable for sensitive mediums. Positive displacement pumps, on the other hand, operate at lower velocities, resulting in very little shear.

3. Pump performance: The flow of centrifugal pumps varies with pressure change, whereas the flow of positive displacement pumps remains constant with pressure change. Flow can be controlled by changing the speed of both pumps.

4. Cavitation: Centrifugal pumps are more susceptible to cavitation than positive displacement pumps due to the presence of entrapped gases. Furthermore, centrifugal pumps are more prone to overheating when operating at low flow rates.

5. Cost: A positive displacement pump's operational and maintenance costs are typically lower than those of a centrifugal pump. Depending on the positive displacement pump type, the initial cost can be higher or lower than that of a centrifugal pump. Positive displacement pump seals last longer than centrifugal pump seals because of their low-speed operation.
