Description
This small but tough part acts like a steady rail. It guides the pump vanes, keeping them in the right position as they slide in and out. This guidance stops the vanes from wobbling, sticking, or wearing down too fast.
A well-guided vane means your pump runs better. It creates a stronger vacuum, runs more quietly, and uses less energy. It also helps your pump last much longer by preventing uneven wear inside.
This is the exact, Leybold part your pump needs. It replaces part number 450031 (also known as cross-reference L0250). It’s made from stainless steel, which is strong and resists corrosion from oil and moisture.
Use this guide pin for your Trivac D1.2E, D2.5E, D5E, D10E (including 2 Series), or D16E pump model. Replacing a worn guide pin during maintenance is a smart way to protect your pump’s performance for years to come.
