Zoomlion Concrete Pump Spectacle Plate

Spectacle wear plate and cutting ring sourcing for Zoomlion trailer concrete pumps. The pair is sized to the pump, and the model code tells you which pump you have: HBT60.13.118RS is a 60 m3/h machine at 13 MPa, HBT80.16.174RSU an 80 m3/h machine at 16 MPa, and the S-valve, spectacle plate and cutting ring behind the higher pressure are different parts. Plate and ring are always replaced as a pair: a fresh ring run against a grooved plate loses its seal within a few hundred cubic metres and lets slurry blow back into the hopper, which is normally the symptom that started the enquiry. Send the bore diameter and centre distance you measure on the old plate, and say whether you want the standard hardfaced pair or the tungsten carbide insert version. Carbide costs more per set and usually costs less per cubic metre on continuous pours in crushed granite or basalt aggregate. The S-valve wear sleeve and the seal ring behind the cutting ring are quoted with the pair if you tell us the hours since the last change.
