Spacer ring, Steel, 35 x 29 x 1 mm, Leybold Trivac E Series, Part# 440023

Part # 440023, Steel Spacer Ring - 35 x 29 x 1mm compatible with Leybold Trivac D E Series rotary vane vacuum pumps. spacer ring (also known as a spacer sleeve or spacer bushing) serves as a critical component within a rotary vane pump. Its primary role is to maintain the proper spacing between the rotating components, specifically the rotor and the stator. By ensuring the correct gap, the spacer ring allows for smooth operation and prevents undesirable contact between the rotor and stator. Rotary vane pumps rely on the movement of vanes (blades) within the pump chamber. The spacer ring ensures that the vanes maintain the correct distance from the stator, allowing for efficient gas compression. Regular inspection of the spacer ring is crucial. If wear or damage is observed, prompt replacement is necessary to maintain pump efficiency and prevent further issues.
