The oil level of the bearing box can be controlled by the constant oil cup. The legs of the pump body can withstand any load from the pipe and pass directly to the foundation. In this way, the rotor will not be bent by the pump to withstand the pump load, so as to ensure the best bearing life. Due to the larger flow area, thereby reducing blockage. Pump rotation direction, from the drive end, clockwise. Power-driven motor or internal combustion engine. Pump unit can be equipped with a complete deflation device, is conducive to the exhaust pipe suction.
