This small but important spring is part of the pressure bypass system inside Busch Panda vacuum pumps. It helps regulate internal pressure and protects the pump from damage. Fits WV1000B, WV1000C, and WV2000C models
It provides the correct pressure to close the inlet valve after each cycle. A good spring stops backflow and keeps your pump pulling strong.
