Tobee® TG12x10G Dredging Sand Pump Shaft Seal Arrangement:

Packing Seal is a general shaft seal.It applys to various pumping conditions, PTFE and Graphite materials of Packing can be used in high corrosive slurries or high temperature conditions.Using ceramic shaft sleeve,For high abrasion conditions, The ceramic shaft sleeve is available.

Expeller Seal is an impeller force of reversed centrifugal force, preventing slurry leakage. Expeller seal can be used on the single-stage pump when the positive pressure of pump inlet is no more than 10% of pump outlet pressure or on the first-stage pump in the pump series.

Mechanical Seal is advanced sealing technique without sealing leakage, integrating construction, convenient installation & replacement, various constructions suit for all kinds of conditions.
