Q&A: Q: Why does our rubber impeller / liner look melted? A: This can be due to a number of reasons: 1.Cavitation with a rubber impeller. Rubber does not pit in the same way that high chrome does. 2. The pump is turning too fast which makes the tip speed too high. When the max tip speed is exceeded, the rubber starts to delaminate and disintegrate. 3. The discharge head is too great or a valve is closed. The fluid thrashes around inside the pump which causes a build-up of heat and can lead to the rubber melting. 4. If the impeller is incorrectly adjusted, it can rub against the liner which causes both to heat up and disintegrate.

❓ Which kind of tool steel do you use for punch making, 1.2379 / D2/ DC53 / SKD11 /Cr12MoV or any other grade? 🏗 Ningshing keeps stock of finished tool steel standard plate. ✅ Size 8-120 x 100-300 mm ✅ Tol. +0.1/-0 mm 👉 To reach high hardness of over 60 HRC, cryogenic treatment is a crucial procedure, that is done immediately by liquid nitrogen as soon as quenching finished. Tempering is necessary as a last step. #toolsteel #punch #standardplate #HARDNESS #hardnesstesting #cryogenictreatment #quenching #tempering #Ningshing #PrecisionMachinery
