gland seal flushing on centrifugal slurry pumps keeps the slurry being pumped from entering the gland seal area. it runs at a slightly higher pressure than the centrifugal pump to create a water seal keeping the slurry out of the gland seal area.
why mclanahan slurry pumps. mclanahan slurry pumps feature a split casing design to allow easy access to the liners the impeller and the gland for maintenance. most slurry pumps come with an assembly aid arm to support the suction casing during impeller replacement and gland maintenance.
a diverse range of horizontal slurry pumps designed for the toughest duties weir minerals horizontal pumps deliver exceptional performance the warman® and galigher® horizontal slurry pump range is one of the world’s most comprehensive range of centrifugal slurry pumps for use in mining chemical and industrial applications.
slurry pumps used in oil sands mining facilities are equipped with gland water seals. clean pressurized gland water is pumped into the stuffing box protecting the shaft from the abraisive process slurry.a steady supply of gland seal water is critical to maintaining operation of any bitumen production facility. even a brief disruption can result in severe pump damage.
slurry pump gland seals are commonly employed in mineral processing pumps to separate the pumped fluid (slurry) from the external environment particularly in duties where the process pressure is high (may be up to 7 mpa) the temperature is high (up to 150 °c) the solids concentration cw exceeds 5% and the fluid is corrosive or some combination of these.
slurry pumping handbook – au page 6 issued: feb 2000 the centrifugal slurry pump must be designed to allow the passage of abrasive particles which can at time be extremely large. the largest warman slurry pump for example can pump particles up to 530mm in spherical size. slurry pumps therefore need much wider and heavier impellers to
