Description
Replacing the valve plate is a key repair that can bring an underperforming pump back to life. This part, number 40175019, is the official Leybold replacement. It’s made to the original specifications for a perfect fit.
Using this part restores the gas control your pump needs. It helps bring back strong, stable vacuum performance and reliable operation.
If this plate is worn, warped, or damaged, the seal isn’t perfect. Gas can leak back, making your pump struggle.
You might notice it takes longer to reach the desired vacuum. Or the pump might not reach its full strength. It has to work harder, which can lead to more wear on other parts.
