PDPC and LWPC

Pumpdown plug and liner wiper plug

Separate cement and displacement fluids efficiently

The pump-down plug (PDPC) and liner wiper plug (LWPC) separate cement from the displacement fluid during liner cementing operations. Both plugs are required because of the large ID difference between the workstring and the liner.

LWPCs and PDPCs are manufactured from high-grade aluminum, enabling rapid, easy drillout with a PDC bit.
