The Model 20 concrete pump is a small, lightweight pumping unit with a compact structure, flexible movement and simple operation. It is suitable for small construction scenarios, with a low entry threshold and strong practicality. Equipped with a stable hydraulic pumping system, it can deliver 20-25 m3 per hour, with a vertical conveying height of 50-60 m and a horizontal conveying distance of 120-150 m, and can convey aggregate with a maximum particle size of 20 mm, meeting the needs of conventional fine aggregate and ordinary concrete pumping. The equipment has low energy consumption, a low failure rate and low operating noise, and comes with wireless remote control for convenient and labor-saving operation. It is mainly suitable for small and medium projects such as rural self-built houses, small plant pouring, floor construction, courtyard renovation and small slope protection, and is especially suitable for confined sites where large equipment cannot enter. It is a cost-effective pumping unit for small infrastructure works.
