Plate, Spring, Non Return Valve, Pfeiffer, DUO, Part# 380048

This spring plate is made for one specific pump model:

• Pfeiffer DUO125

The DUO125 is a two-stage rotary vane vacuum pump. It is used in many industrial and laboratory applications where a strong, reliable vacuum is needed.

If you are doing a major repair on your DUO125 pump, you will need this spring plate. It comes as a key part inside the Major Overhaul Kit for Pfeiffer DUO 125 (Part# PMK025 / PKE02037-T) .

When you buy that overhaul kit, you get two of these spring plates (quantity: 2) . The kit also includes many other parts like O-rings, valves, sleeves, and more.

So if you buy the full overhaul kit, this spring plate is already inside. But if you only need to replace the spring plate by itself, now you know the exact part number to order.

When you replace the spring plate, take a good look at the non return valve itself. Check for any damage or wear. Clean off any old oil or debris. Make sure the spring plate sits correctly and moves freely in its place.

Keep your Pfeiffer DUO125 pump running strong with the right spring plate. Get Part# 380048.
