Plate, Valve, DUO250/255-Pfeiffer DUO, Part# 380049

This is the Pfeiffer Valve Plate, Part# 380049. It is made to the exact factory specifications. That means it fits right the first time.

This valve plate works on two specific Pfeiffer pump models:

• Pfeiffer DUO250A (standard version)

• Pfeiffer DUO255M (Index C) (magnetic coupling version) 

Both of these are large, powerful two-stage rotary vane pumps. They are built for tough industrial jobs.

Part of a Complete Overhaul
If you are doing a major repair on your DUO250A pump, you will need this valve plate. It comes as a key part inside the Major Overhaul Kit for Pfeiffer DUO 250A (Part# PMK027 / PKE02022-T) .

That overhaul kit includes many parts:

• Exhaust valve

• Stamp valve

• Hydraulic piston

• Sight glass and gasket

• Various O-rings

• And this valve plate 

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