Ground concrete pump spare parts consist of hydromechanical and wear components designed for operating pressures between 50 and 140 bar. The delivery cylinder is manufactured from alloy steel with induction hardening depth of 2 to 4 millimeters. Surface hardness typically ranges from 58 to 64 HRC with internal roughness below 0.8 micrometers. Wear plates and cutting rings are produced from high chromium cast iron with hardness of 60 to 67 HRC. The S valve operates under cyclic stresses up to 250 megapascals and is assembled with ±0.03 millimeter tolerance. Delivery pipes with wall thickness of 4 to 7 millimeters are reinforced for abrasion resistance.

Structural design is based on slurry wear analysis and cyclic fatigue with a safety factor between 1.5 and 2.2. Service life of wear components varies from 25000 to 90000 cubic meters depending on concrete aggregate grading. Rubber pistons are manufactured from NBR or polyurethane compounds with hardness between 75 and 95 Shore A. Shafts and bushings are machined from 42CrMo4 steel with tensile strength of 900 to 1100 megapascals. Hydrostatic pressure testing is performed up to 1.5 times nominal pressure. Quality control includes hardness testing, concentricity inspection, and dimensional measurement with 0.02 millimeter precision.You can order and buy supporting cover from Iran by contacting us through whatsaap and email.
