Product Description
WD-series pumps are horizontal corrosion-resistant centrifugal pumps, with spacious impeller flow channel and superior hydraulic performance. The back shroud of impeller is equipped with back blade, which can reduce media leakage. In order to recover pump’s performance when flow passage components are worn and corroded, axial adjusting device is equipped to adjust the space between impeller and pump body. Variable types of shaft seal (including mechanical seal, dynamic seal + packing seal, dynamic seal + K-type seal) are adopted to meet the shaft sealing requirements for carrying variable media

Impeller Features
1) The impeller is designed as open impeller, semi-open impeller, vortex impeller and closed impeller.
2) The closed impeller is designed as a wide-flow impeller according to the principle of multi-phase flow, which is beneficial to the passage of solid medium without clogging
3) The impeller is designed with back blades, and the front back blades are used to prevent the medium from flowing back toward the pump inlet.
4) The blades are used to reduce the axial leakage pressure and balance the axial force.
5) The impeller is mounted on the shaft with a conical fit for easy assembly and disassembly.
6) The impeller is fastened with impeller nut and locking screw.
Application
It's widely used in petroleum oil, chemical industry, rubber, leather, food industry, grease, boilers, construction, road maintenance, pharmaceutical, plastics, rubber, synthetic fiber textile, printing and dyeing and other industrial fields.
