BMX Series Magnetic Drive Swirl Pumps

Product description

BMX series (vertical) magnetic drive rotary pump is our company according to the market needs to introduce foreign advanced technology based on the development of a non-blocking pump, the use of magnetic coupling transmission design, completely solve the problem of dynamic mechanical seal leakage, the use of fully eddy shape, open impeller and wide flow design, the gap between the impeller and the pump shell and the discharge diameter is the same. Single stage single suction horizontal installation, horizontal suction, tangential discharge. The pump has high efficiency, low vibration, stable operation, the impeller inlet has the effect of stirring foreign matter, has strong anti-blocking ability and good cavitation performance, suitable for the complete delivery of particulate matter and fiber medium magnetic pump.

Suitable for petrochemical, plastic, rubber, pulp and paper, metallurgy, sewage treatment and other industries, conveying medium containing large particles, fiber, dirt or high gas content.

Design features

The structure design of the pump body and impeller of the magnetic drive cyclone pump embodies a new design concept, which is novel, unique and practical. The impeller rotates in the pump body and drives the medium in the flow passage of the pump body to form a vortex. The solid particles with large particles and strong wear characteristics flow to the center of the pump body flow passage along the longitudinal vortex, and the smaller particles with weak wear characteristics contact with the pump body chamber and the impeller surface. Most of the coarse particle media do not directly scour the impeller and the pump body, the impeller and the pump body are reduced due to scour and wear damage, so that the pump body and the impeller life is greatly extended.

The impeller of the magnetic drive cyclone pump is open type. Impeller and front cover (wear plate) no clearance requirements (the impeller clearance can reach 30 ~ 100mm), the medium into the pump body with the impeller rotation in the pump body flow passage formed eddy, most of the solid particles are not through the impeller and directly thrown from the outlet, medium containing solid particles do not directly wash, wear the impeller, and the impeller is not easy to plug. Even if the flow parts in the occurrence of slight wear, the pump performance parameters will not change too much, so that the impeller life is greatly extended. The impeller structure can delay the scaling cycle of the medium on the impeller for the medium precipitated by crystals.

Working principle

The working principle of the pump is that when the impeller rotates, the energy of the medium is increased by the centrifugal force, and the medium between the blades is driven by the blades and the impeller moves together. The medium near the top of the impeller outlet forms a through-flow due to the large centrifugal force, and the medium in the middle of the impeller forms a circulation flow.

Through flow through the outlet of the pump cavity outflow, form a certain head; The solid particles and fibers in the medium obtain energy under the action of circulating flow. Most of them do not pass through the impeller, but are discharged by the pump outlet after moving in the bladed cavity, so as to achieve the purpose of conveying complex media or fluids containing impurities:

(1) Good non-blocking performance, can pass through the solid particles equivalent to the pump outlet diameter; (2) most of the solid particles do not pass through the impeller, the service life of the impeller is long; ③ Pump suction performance is good, with good cavitation performance; (4) It can pump liquid with high gas holdup; ⑤ can pump high concentration and high viscosity liquid; The standard duplex stainless steel material, wear resistance, excellent corrosion resistance.
