With their unique sliding vane technology, sliding vane pumps have revolutionized the mechanical and industrial engineering industry. With a revolutionary rotary vane design that enables the pumps to self-adjust for wear, assisting in the maintenance of flow rates, sliding vane pumps allow for excellent self-priming and dry-run capabilities, as well as long-term performance and trouble-free operation.

Sliding vane pumps consist of an eccentric ring and a rotor with slots that house the vanes, which can move radially as the rotor rotates in the ring. The vanes move outward as they revolve past the suction port, defining a volume defined by consecutive vanes, the rotor, and the ring wall. As it moves past the suction port, this volume draws fluid in and seals it off, and the eccentricity of the ring and the rotor pushes the vanes into the slots, reducing volume and forcing fluid out through a discharge port.

Common Applications for Sliding Vane Pumps

Sliding vane pumps are well suited for various applications and are intended to handle a wide range of low- to medium-viscosity fluids, including those at high temperatures. Here are some of the most common applications of sliding vane pumps.

Process Applications

Many of the commodities used in industrial process applications are difficult to handle, frequently toxic or corrosive, difficult to seal, and costly to purchase. Sliding vane pumps impart a very low shear rate to the material being handled, resulting in a smooth, almost pulsation-less flow. Sliding vane pumps also adjust to compensate for regular wear, resulting in efficient performance over the product’s life.

Energy Applications

Sliding vane pumps are commonly used to load, transfer, unload, and meter petroleum and gases. Sliding vane pumps are highly dependable, simple to maintain, and widely regarded as the world’s most effective pump technology for moving thin and medium viscosity petroleum-based liquids.

Transport Applications

Sliding vane pump technology has a proven history in truck-mounted applications ranging from thin liquids and liquefied gases to viscous products and abrasive materials. The sliding vane design compensates for everyday wear in the pumping chamber, ensuring efficient performance for the duration of the product’s life.

Military Applications

Sliding vane pumps are also used in various shore-based and mobile equipment applications throughout the United States military and around the world. Sliding vane pump technology is ideal for shipboard pumping applications with long, tortuous piping runs, high suction lift requirements, and confined equipment mounting areas.

5 Benefits of Using Sliding Vane Pumps

Sliding vane pumps provide a straightforward design and the efficient performance required for effective high-volume liquid transfer in various chemical-processing applications. They also provide several other key advantages, including the following.


Sliding vane pumps are self-priming, which gives them an advantage over many other pumps that require costly priming systems to operate.


The unique sliding vane technology self-adjusts for wear during operation, allowing the user to maintain consistent flow rates.

Dependable Performance

Sliding vane pump technology is a simple yet elegant fluid transfer solution that provides trouble-free operation, long-term performance, and consistent results.

Low Maintenance

Sliding vane pumps are simple to maintain and can be replaced without removing the pump from the piping system.


Sliding vane pumps require far less horsepower than many other types of pumps, allowing you to run more efficiently, save money on energy, and extend the life of your drive motors.
