AQUASEAL Pumps used for Hydraulic Ash Handing & Dredging systems are rugged pumps for efficient performance, long life and economical operation designed to handle pieces of solid material.

The initial high efficiency of the pump and characteristics are maintained due to the "AQUASEAL" principle which prevents abrasive material from entering and enlarging the running clearances between the rotating impeller and stationary parts, by a continuous flow of a small stream of clean water. This water also effectively protects other important parts from the abrasive-laden water. The stream water pressure is regulated by a globe valve.

A large number of these pumps have been working in various power stations since Sixties.

VARIABLE SPEED-DRIVE

VARIABLE SPEED-DRIVE

A special variable speed V-Belt drive can be provided whereby pumps speeds may be adjusted within desired limits to improve the discharge which might have been reduced due to wear on the impeller, in course of time.

MATERIALS OF CONSTRUCTION

LIQUID-END          All components in contact with water containing abrasive material are manufactured from high quality, abrasion resistant alloy-iron having a minimum Brinnel Hardness of 500. The unusual resistance to wear and superior hardness of this material assures long life and improved resistance to the action of abrasive materials, resulting in substantial operating economies. EFFICIENCY    Liners and Impellers are manufactured from special alloys to close tolerances, which allow to achieve very high efficiency.

BEARINGS Extra large size heavy-duty Bearings have been selected to support Shaft, for extra long life requiring minimum of maintenance. Extra large size heavy-duty Bearings have been selected to support Shaft, for extra long life requiring minimum of maintenance.

FLOW MORE AQUASEAL pumps are available in several sizes to cover practically all requirements of such pumps and in addition they are also available with variable speed units to permit variation of the pump speed through V-Belt drive, to achieve better adaptation of the pumping capacity to the actual site conditions.
