Correct selection and use of mechanical seals for solid-liquid two-phase flow pumps

When selecting the type for the solid-liquid two-phase flow pump, the effects of particles should be avoided . There are two ways for mechanical seals to solve the problem of adverse effects brought by particle media: one is to set up some additional internal structures for the mechanical seal or to take auxiliary measures such as resorting to screw seals, lip seals, sealing liquid, flushing water, water tanks or oil tanks to establish a liquid barrier to prevent particles accumulation, etc., or to adopt external devices (such as cyclone solid-liquid separators, magnetic filters, etc.). These two approaches can be used for more important occasions and important equipments.
