Feature of Kosaka Submerged Pump

Kosaka Submerged Pump apply the unique sealing system with mechanical seal.

One for a cargo and another for hydraulic oil in pressurized cofferdam, which is designed to minimize leakage, zero level. During the operation of the submerged cargo pump , the pressure if the cofferdam is over the back pressure of the impeller but under the pressure if hydraulic oil. Under this relation with the mechanical seals, the leakage is minimized and a pit in the cofferdam has sufficient space to hold the accumulated leakage cargo or oil. The pit level is under the sealing surface of the mechanical seal to achieve no contamination. And the leakage of liquid is small quantity comparatively.

And Kosaka Mechanical Seal has durability very much and good sealing against sludge of super phosphoric acid.
