Detailed introduction of industrial filling pump
Definition and application fields of industrial filling pumps
Industrial filling pump is a mechanical equipment specifically used for transporting liquids, widely used in multiple industrial fields, especially playing a key role in mining filling, sewage treatment, solid waste treatment, and other aspects. Its main application areas include:


Mine filling: used for tailings filling in coal mining, metal mines, and non-metal mines.

Wastewater treatment: fields such as metallurgical and petrochemical industry wastewater treatment and solid waste treatment.

Applications in special environments: such as long-distance and high lift transport of sewage sludge from sewage treatment plants, dredging of rivers and lakes, tunnel construction, sea reclamation and other fields.
Working principle of industrial filling pump
The filling industrial pump mainly uses centrifugal force and the action of the impeller to push the liquid out. When the motor drives the shaft to rotate, the impeller on the shaft also rotates accordingly. During the rotation process, the centrifugal force acting on the impeller draws liquid into the pump body from the inlet, and then pushes the liquid towards the outlet through the rotation of the impeller. The specific work process is as follows:

Inhalation of liquid
After the motor starts, the shaft begins to rotate and the impeller also rotates accordingly. As the impeller rotates, the liquid is subjected to centrifugal force and sucked into the pump body. The suction of liquid mainly relies on the negative pressure at the inlet of the pump.

Transport liquids
When the liquid is sucked into the pump body, it will be pushed towards the outlet of the pump body through the rotation of the impeller.

Discharge liquid
When the liquid is pushed to the outlet, it is transported to the place where it needs to be conveyed through the pipeline at the outlet. This process is accomplished through the pressure at the outlet of the pump.

Technical points and system functional characteristics of industrial filling pumps
Technical points
The design of the filling pump achieves a split type design for the overall structure, upgrades and optimizations for the conveying cylinder and main oil cylinder, multi-stage sealing structure for the front and rear bearing seats and hydraulic motor contacts, multi-stage lubrication for the central lubrication system, large pumping distance, central integrated control, and imported German Rexroth products for the hydraulic power pack pump valve. The following requirements are met:

The system equipment adopts an economical, energy-saving, and environmentally friendly system. The device has a compact structure, small footprint, simple and flexible pipeline layout, and can be laid overhead or in trenches, vertically raised, and turned at various angles.
The pumping volume of the filling pump can be continuously adjusted according to the load changes of the system.
The entire conveying system can coordinate and match, work reliably, and operate stably. The conveying process is fully sealed, pollution-free, and the working environment is clean.
The filling pump can perform automatic and incremental pumping. Simple operation, low failure rate, unmanned operation throughout the process, and low operation and maintenance costs. The system can adapt to 24-hour uninterrupted continuous operation.
The filling and conveying system realizes automatic control, and all equipment has linkage operation.
The filling and conveying system adopts mature and advanced standard components in the design and selection of its main parts, making it highly interchangeable. At the same time, specialized optimization design has been carried out for the use and maintenance of the system and equipment, making operation, maintenance, and repair more convenient when conditions permit.
