The diesel long shaft deep well pump is equipped with a double rolling bearing structure within its bearing components. In contrast, many competing long-shaft fire pumps depend solely on a thrust bearing, which is responsible for supporting both the rotor's weight and the axial force of the pump. This design inadequately addresses the radial force, resulting in frequent operational vibrations that can lead to accelerated bearing wear and problems such as the loosening and leaking of the packing gland. In comparison, the XBC series long-axis fire pumps feature a deep groove ball bearing positioned above the thrust bearing, effectively balancing both axial and radial forces, which contributes to smoother and more dependable pump operation.
HRZL is willing to customize the pump functions based on your actual needs, striving to satisfy every customer. Our quality assurance department strictly implements the quality inspection process to ensure the reliability of the pump.
