The invention further relates to a radial wearplate (13) and to a method for removing said wearplate (13) from the pump (1).

A wear plate assembly is in slidable communication with the rotatable cartridge assembly.

The nose section (4) is constructed from a thin-walled wear plate (9) integrally joined with the tool body and a thin-walled driver guide (8) joined to the front part of the wear plate (9).

A edge for attaching to a moldboard, having a rearwardly protruding trailing wear plate is disclosed.

The wear plate assembly has a center plate with a solid portion, an opening for passing the carrier, and an air-pass opening.

With drive, inlet with wear plate, bypass in the inlet and aspiration connection.

The bottom wear plate is designed to last, with thicker protection toward the back of the plate where the most wear occurs.

Typically this will involve lubricant changes, replacement of wear plate and filter media.

A forward end member (17) of the contact arm (15) is placed so as to be slidable along a rear surface of the wear plate (9).

Hardox 500 Tuf delivers exceptional strength, hardness and toughness in one and the same wear plate.

The wearplate (13) comprises a surrounding edge (17 - 20) with straight and curved parts and a protrusion (21) which is situated along part of the edge (17 - 20).
