Product Introduction
This series of pumps are single-stage single-suction, cantilever, horizontal structure. The pump body, the pump cover and the joint plate are connected by a clamp band. Lubrication form grease lubrication. It is mainly used for conveying strong abrasive materials that are too large to be conveyed by general slurry pumps. Widely used in coal, electricity, transportation, river dredging, municipal engineering and other fields. Can also be used for river sand mining and mining vessels. This series of pumps are single-stage, single-suction, cantilever, horizontal structure. The pump body, the pump cover and the joint plate are connected by a clamp band. The pump body and the pump cover are clamped by special clamps, and the discharge direction of the pump can be at any position of 360 degrees, which is easy to install and use.
The bearing assembly of the gravel pump adopts a cylindrical structure, which is convenient to adjust the gap between the impeller and the pump body, and can be removed as a whole during maintenance. Lubrication form grease lubrication.
The gravel pump has a wide flow channel, good cavitation performance, high efficiency and abrasion resistance.
The main transmission mode is V-shaped V-belt drive, elastic coupling drive, gear reducer drive, hydraulic coupler drive, variable frequency drive, SCR speed control and so on.
The flow components are made of wear-resistant alloy cast iron with high hardness.
The use of a variety of speeds and a variety of variants, so that the pump in the best operating conditions. Long service life, high operating efficiency, can meet many types of harsh transportation conditions.
Pump and drive machine can choose direct drive, V-belt drive, hydraulic coupling drive, reducer drive. The discharge direction of the pump can be at any position of 360 °, which has the advantages of convenient installation, good cavitation and abrasion resistance. The inlet of each type of pump is in the horizontal direction, and the pump rotates in time from the transmission direction, or it can rotate counterclockwise as required.

Sealing mode
The shaft seal of gravel pump has packing seal and vice impeller seal.
1. Packing seal: used for suction or backflow state. Shaft seal water pressure should be higher than the pump outlet pressure 35Kpa, shaft seal water see below.
2. Vice impeller seal: generally used for backward irrigation state. The backward water head does not exceed 10% of the total water head of the pump, and the shaft power will increase by about 5%.
