GMZ typeOre slurry pumpAll adopt the same series of transmission, including bracket and bearing components. The pump shaft has a large diameter, good rigidity, short cantilever, and will not bend or vibrate under harsh working conditions.

Efficient wear-resistant slurry pump and ash pump are single-stage single suction, axial suction cantilever horizontal centrifugal pumps, which can be widely used in metallurgy, mining, power, coal mining, water conservancy, chemical industry, light industry, petroleum and other departments to transport abrasive or corrosive slurry containing a large amount of solid materials.

GMZ typeOre slurry pumpstructure

1. Pump head section: The GMZ series pump has a dual pump casing structure, consisting of a front pump casing, a rear pump casing, and a replaceable overcurrent section (including impeller, volute shell, front guard plate, and rear guard plate). The front and rear pump casings are made of gray cast iron or ductile iron according to the working pressure, vertically split and connected with bolts. The rear pump casing has a stopper and a bracket connected with bolts. The pump outlet can be rotated and installed at eight angles. The front and rear cover plates of the impeller are equipped with back blades to reduce leakage and improve the service life and efficiency of the pump. The inlet of each type of pump is horizontal, and the pump rotates clockwise when viewed from the transmission direction.

2. Shaft seal part: There are three forms of shaft seals: secondary impeller shaft seal and packing shaft seal, and mechanical seal.

(1) Auxiliary impeller shaft seal: When the positive pressure value at the pump inlet is not greater than 10% of the pump outlet pressure value, a single-stage pump or a multi-stage series third stage pump can use an auxiliary impeller shaft seal. The auxiliary impeller shaft seal has the advantages of not diluting the slurry and good sealing effect.

(2) Packing shaft seal: The packing shaft seal has a simple structure and is easy to maintain. It requires the use of shaft seal water. For working conditions that are not suitable for using a secondary impeller shaft seal and pump suction working conditions, packing shaft seals can be used.

(3) Mechanical seal: For working conditions that are not suitable for the above two types of shaft seals, mechanical seals are used to reduce the maintenance frequency of the shaft seal part.

3. Transmission part: This series of pumps adopts the same series of transmission, including bracket and bearing components. The pump shaft has a large diameter, good rigidity, short cantilever, and will not bend or vibrate under harsh working conditions. The bearings are selected as a combination of single row tapered roller bearings and angular contact ball bearings, which can withstand the large axial and radial loads of the pump. The bearings are lubricated with lithium based grease, which has the advantages of high oil film strength; Good adhesion of oil and fat, not easily lost, and long-lasting use; The sealing is simple, and the bearing body is equipped with sealed end caps at both ends, which can effectively prevent impurities such as slurry from entering the bearing.
