Description

Specification

Application

Structure type: Type DHR slurry pumps are double shell cantilever horizontal centrifugal pump.

Transport materials: They are designed for conveying strong corrosion and high concentration slag slurry.

Lining materials: Wear resistant metal lining and rubber lining , they can be used interchangeably.

Characteristics:

Type DHR, also called Rubber Lined heavy-duty slurry pump.Because this type of pump has thick wear parts and heavy base,Therefore, it is suitable for conveying strong abrasion, high concentration slag slurry or low concentration high lift slag slurry,Within the maximum allowable working pressure range of the pump, it can be used in series.Among them, type DHR pump is suitable for conveying low concentration high lift slag slurry or high concentration low abrasion high lift slag slurry.The above types of pumps can also be used for slag slurry with certain abrasiveness.

Construction Design:

Shaft Seal Module Design

Packing Seal，Expeller Seal，Mechanical Seal

Eight exit directions:

The outlet position of the pump can be spaced at 45 ℃ as required, It can be rotated at eight different angles to install and use. This type of pump can also be used in series.

Four Transmission Modes：
