1, All bearings adopt the imported products with Japanese NSK to ensure the precise orientation of impeller and high stability during the running.
2, The material of the impeller is welded with nodular iron or steel to ensure the high stability and increase the lifetime of the pump greatly during any harsh conditions.
3, The pulley (when the pump is driven by the belt) adopts standard high precise taper bushing pulley to keep the reliable running and increase the lifetime; also it is easy to dismantle.
