concrete pump , Iran
A concrete pump is a hydraulic machine designed to transport fresh concrete with a slump of 80 to 220 mm at operating pressures of 60 to 130 bar. It consists of twin delivery cylinders, an S or Rock valve system, a hydraulic unit rated 90 to 250 kW, and a 400 to 800 liter hopper. Pumping capacity ranges from 30 to 180 cubic meters per hour depending on the model. Delivery pipe internal diameter is typically 100 to 125 mm to maintain pressure loss below 0.5 bar per 10 meters. Structural safety factor of boom systems is at least 1.8 against yield stress of S355 steel.
Structurally, cylinders are manufactured from hardened alloy steel with 55 to 62 HRC hardness to withstand over 25000 cubic meters of concrete wear. Control systems may use electrohydraulic PLC units with 0 to 250 bar pressure sensors. Boom reach in truck mounted models varies from 24 to 58 meters. Diesel engine fuel consumption at rated load is approximately 15 to 35 liters per hour. Hydraulic circuits are pressure tested at 1.5 times nominal pressure in accordance with ISO 4413.You can order and buy concrete pump from Iran by contacting us through whatsaap and email.

Signs of Concrete Pump Parts Failure and Replacement Timing in iran
A sudden increase in working pressure exceeding 15 percent of the nominal value is the first indicator of wear in concrete pump components. A flow rate reduction greater than 10 percent indicates internal leakage in the delivery cylinder or piston seal failure. A rhythmic knocking sound during each pumping cycle typically relates to wear in the spectacle plate and cutting ring. Hairline cracks in delivery pipes with wall thickness below 4 millimeters significantly increase rupture risk above 150 bar pressure. Hydraulic oil leakage or system temperatures exceeding 75 degrees Celsius indicate sealing efficiency loss. Wear parts are generally replaced after pumping 20000 to 40000 cubic meters of concrete. Operating hour records and periodic vibration analysis provide the most accurate engineering based replacement prediction.
