Sliding Vane Pump Overview
Sliding vane pumps are positive displacement pumps that can transfer and flow thin liquids and viscous fluids ranging up to 10.000 centistokes. You can use the pump to transfer many shear-sensitive liquids such as cream, glue, paint, etc. The sliding vane pumps have multiple sliding vanes (thus the name), which can slide in and out of slots in the pump rotor.
The pump turns the rotor, creating a centrifugal force that pushes the liquid from the inlet to the discharge outlet. These pumps create pumping chambers within the machine, allowing viscous liquids to flow from one container to another. The fluid moves around the pump casing until it reaches the discharge port.

Why are Sliding Vane Pumps Important?
Industrial applications require users to operate with different kinds of fluids. Many of these fluids are toxic or corrosive, expensive, or difficult to seal. The sliding vane pumps create individual chambers in the pumps for each of these pumps, making them ideal for transferring these fluids.
Some of these pumps also have shaft sealing options, making them ideal for complex chemical processes.
These pumps have a meager shear rate as their sliding vanes can adjust themselves according to the liquid flow. The pumps adjust themselves to create the lightest machine wear and provide pumping performance simultaneously.
Sliding vane pumps don’t require excessive maintenance, making them ideal for long-term use. You need a few simple tools and training to ensure your pumps perform correctly.
How do Sliding Vane Pumps Work?
The sliding vane pumps have a rotor connected to the vanes that extract liquid for each vane individually. The liquid goes from the inlet into the pumping chamber. Each vane in the pump provides positive displacement and mechanical push to move the liquid.
The vane contact uses three different forces to move the liquids, including the centrifugal force for the rotation in the rotor. It also includes the push rods moving in opposing directions in the vanes. Lastly, it contains the liquid pressure inducted through the vane grooves or acting on the vane rear.
The pump displaces a fixed amount of liquid creating a constant pressure in the pump, and the changes in pressure have minimal effects on the pump. The sliding vane pumps maximize fluid movement and reduce energy wastage, turbulence, and slippage.
Advantages of Sliding Vane Pumps
Sliding vane pumps offer several advantages because of their advanced designs. These benefits include the following:
Consistent Flow Rates
The sliding vanes in the pump adjust themselves and allow consistent liquid transfer.
Self Priming Options
Sliding vane pumps have self-priming capabilities, removing the need for costly priming systems.
The sliding vane pumps can run in difficult situations because of their extended dry-run capability.
These pumps have easy operations, simple maintenance, and sustainable performance, making them ideal for long-term industrial applications.
Low life-cycle Costs
Industrial users do not have to worry about changing the sliding vane pumps as you can repair and renew the pumps easily.
The sliding vane pumps have a simple vane system that moves in and out of chambers allowing the liquid transfer. These pumps have high performance, low cost, and easy maintenance options, ideal for large-scale applications.
