Main Features

 

Wet-End Design

The unique segmented clamp ring on larger size units and solid on smaller pumps, facilitates casing rotation to any angle, reducing the need for costly high wearing bends. Minimal maintenance is required.
1. Impeller – front and back shroud expulsion vanes reduce gland pressure and intrusion of high concentrations of solids in the gland area. Efficiency is maintained by minimizing suction side recirculation. Specially designed and shaped impeller vanes allow the handling of extraordinarily large particles. The unique casing design and sealing vanes prevent abrasive solids intrusion at the sealing faces.
2. Casing – The large, robust casing has been designed to reduce internal velocities resulting in minimum efficiency loss and improved casing wear life. The casing is made up of three components to reduce maintenance time and costs associated with a one piece design.
 

 

Impeller

The impeller generally has three vanes or five vanes and wide application range.It is made of wear-resistant high chromium alloy cast iron(hardness≥58HRC,impact toughness≥9J/cm2).The impeller is fixed on the pump shaft with double thread,and the thread tolerances are inspected according to the pitch diameter of thread.Disassembly rings are installed at the rear of the shaft sleeve to make maintenance eas

Volute casing

The volute casing is made of wear-resistant and compression-resistant alloy(hardness≥56HRC,impact toughness≥8J/cm2).Advanced smelting technology combined with casting process and heat treatment process guarantees smooth casting surfaces and reliable internal qualiyt.

The bulge test will be carried out after molding,and the test pressure is 2 times of the discharge pressure of the pump.If there no leakage after 20 minutes,strength and tightness,strength and tightness pressure test reports can be issued.

Liner plate

The liner plates are made of wear-resistant high chromium alloy cast iron(hardness≥56HRC,impact toughness≥8J/cm2).
