Stationary concrete pump spare parts include concrete delivery systems, hydraulic circuits, distribution valves, and high strength wear components. Operating pressure typically ranges from 80 to 120 bar, with maximum output capacity between 50 and 140 cubic meters per hour. Delivery cylinders are designed with internal diameters from 180 to 230 millimeters and strokes of 1300 to 2000 millimeters. Concrete pistons use reinforced polyurethane packings capable of withstanding 120 bar pressure. Delivery pipelines are manufactured from alloy steel with hardness between 58 and 64 HRC. Wear plates and cutting rings exceed 550 Brinell hardness to extend service life.

The chassis structure is fabricated from structural steel with minimum yield strength of 355 megapascals to ensure stability under continuous cycles. The hopper includes an agitator rotating at 20 to 30 revolutions per minute to prevent concrete settlement. The S valve or rock valve switches flow direction at 15 to 35 cycles per minute. A hydraulic piston pump rated at 100 to 180 kilowatts delivers 180 to 300 liters per minute. Machining tolerances for pins and bushings are maintained below 0.05 millimeters. Quality control includes hydrostatic pressure testing, leakage inspection, and non destructive examination of load bearing components.You can order and buy bushing from Iran by contacting us through whatsaap and email.
