concrete pump , Iran

Concrete pump spare parts include delivery cylinders, S valves, cutting rings, wear plates, polyurethane pistons, and high pressure delivery pipes. Cylinders are manufactured from 42CrMo4 alloy steel with 55 to 62 HRC surface hardness and surface roughness below Ra 0.4 micrometers. Delivery pipe thickness ranges from 4 to 12 mm with tensile strength above 900 MPa. Assembly tolerance of sealing components is limited to ±0.02 mm to maintain pressure loss below 3 percent. Cutting rings and wear plates are produced from high chromium alloy cast iron with 58 HRC hardness. All components undergo hydrostatic testing at 1.5 times nominal pressure up to 130 bar.

Structurally, wear resistance is designed for more than 20000 to 30000 cubic meters of pumped concrete. Pistons are made of reinforced polyurethane with abrasion loss below 30 mm3 according to ASTM D5963. Clamp and flange connections withstand pressure shocks up to 1.5 times operating pressure. Internal pipe surfaces are induction hardened to a depth of 1.5 to 2.5 mm. A minimum safety factor of 2.0 against base material yield stress is applied. Quality control includes ultrasonic testing, metallurgical analysis, and dimensional inspection according to ISO 9001.You can order and buy concrete pump from Iran by contacting us through whatsaap and email.
