Biogas Engineering Manure and Straw Conveying Pump

The resource utilization of agricultural and animal husbandry manure treatment and the mixing of manure and straw in biogas engineering as raw materials for biogas fermentation have the characteristics of large particle size and strong wear. In the past, screw pumps or slurry pumps were often used, which highlighted some problems during use, such as frequent material blockage and rapid wear of working components. Therefore, the Robosida rotary pump was adopted, which has the ability to pass particles of up to 70mm, solving the problem of material blockage. At the same time, wear-resistant ductile iron pump casing and special wear-resistant steel lining plate are used, with low speed and light component wear. In addition, the clearance between the pump casing and rotor can be adjusted more than twice, saving 70% of spare parts costs. At the same time, for the same rotary pump, the quality of different brands varies greatly. For example, a natural gas company in Anhui used a domestically produced rotary pump, but customers complained about replacing the rotor once a month, frequent shutdowns for maintenance, production cannot be guaranteed, and maintenance costs are high. Adopting the Robustar rotary pump, it has been running for a year without replacing any spare parts, completely solving the pain points of users.
