  • Product Introduction

    The accessories of the slurry pump include impeller, pump body, pump cover, rear guard plate, shaft sleeve, positioning sleeve, water seal ring, packing gland, packing box, bracket, auxiliary impeller, pressure reducing cover, labyrinth ring, etc.

    The main flow components of the slurry pump are the pump body, impeller, and volute. The impeller device in the pump body is located on the shaft and connected to the motor to form a whole. When the motor drives the impeller to rotate, the blades in the impeller force the fluid to rotate, thereby increasing the pressure potential energy and kinetic energy of the fluid. At the same time, the fluid flows from the center to the edge of the impeller under the action of inertial force, and flows out of the impeller at a high speed, passing through the discharge pipeline to achieve the purpose of transportation. There are roughly two types of materials for slurry pump accessories: metal and rubber. The commonly used metal materials for slurry pumps are divided into cast iron, ductile iron, high chromium alloy, stainless steel, and so on. Rubber materials are divided into natural rubber, synthetic rubber, nitrile rubber, etc. Industrial cast iron generally has a carbon content of 2% to 4%. Carbon is mostly present in the form of graphite in cast iron, and sometimes also in the form of cementite. In addition to carbon, cast iron also contains 1% to 3% silicon, as well as elements such as manganese, phosphorus, and sulfur. Alloy cast iron also contains elements such as nickel, chromium, molybdenum, aluminum, copper, boron, vanadium, etc. Carbon and silicon are the main elements that affect the microstructure and properties of cast iron.
