Description
The Busch Carbon Vane, Part# 722000189, is this essential part. It’s specifically designed for the Seco SV1025B pump model. When these vanes are new and the right size, they form a perfect seal against the pump chamber wall.
A vane needs to be strong yet have just the right amount of “give.” It must create a tight seal without causing too much friction or wearing out the pump wall.
Carbon is an ideal choice. It’s naturally durable and wear-resistant. This means the vane itself lasts a long time while also being gentle on the pump’s internal surfaces.
