1, strong self-priming capacity for suction underground tank, the lifting height of up to 6m. 2, high efficiency pump vane by centrifugal force, mechanical thrust, hydraulic pressure of the combined effect, close to the stator curve movement, so that the pump has a unique high efficiency. 3, to maintain the same performance of the self-adjusting slide vane slides out of the rotor slot, constantly replenishing wear, without reducing pump performance. This gear pump is essentially different. 4, the ability to convey shear-sensitive liquid High-performance hydraulic slides designed to pump the pump to reduce the sliding shear on the fluid and agitation, to avoid the resulting changes in the nature of the fluid. 5, reliable sealing For viscosity, high temperature medium characteristics, the use of special mechanical seals, with safety, durability, reliability features. 6, simple maintenance, easy to open the pump cover, put forward the old slide, insert a new slide. In just a few minutes, your pump can get back into work. Daily inspection is equally easy. 7, safe and sensitive pressure to ensure the safety relief valve set in the pump, the export system suddenly closed, the outlet pressure rise does not exceed 0.15Mpa, on the one hand to ensure the safety of pumps and systems, on the other hand, to ensure that the motor is not overloaded .
