Should the wear plate and cutting ring be replaced as a set?

They are a matched pair and wear against each other, so they are normally replaced together. The cutting ring generally wears faster than the wear plate, which is why we supply both matched sets and single pieces for top-up.

Can worn wear parts be rebuilt instead of replaced?

Hard-faced parts can sometimes be weld-repaired and returned to service, which extends the interval. That is a decision for the workshop; we quote replacements either way.

Which pump makes do your parts fit?

Our delivery line and hopper wear parts are selected for interchangeability across the common concrete pump families. Send the machine model, the pipeline diameter, or a photo of the old part and we will confirm the match.

The wear pair first

Inside the hopper, a wear plate and a cutting ring form a matched friction pair: the cutting ring swings with the S-tube and shears the concrete, while the wear plate takes the impact and the sliding load. The design deliberately moves the abrasion onto these two replaceable pieces.

The delivery line

Boom pumps and trailer pumps both run a pipeline that wears through. Alongside the hopper parts we supply the line itself, sized by the standard delivery diameters and supplied by the container load.

Boom elbows and deck elbows
Tapered reducers for stepping between line sizes
Pipe clamps, couplings and gaskets
End hoses

Material matters more than price here

The same shaped part can be made in different wear materials, and the service life and the price move together. Tell us the duty — aggregate size, pumping distance and height, and how the last set failed — and we will quote the material grades that fit rather than the cheapest one on the list.
