The advantages and application range of fire pumps, gear pump principles and non-clogging sewage pumps

Feb 10, 2023
scope of application
      It is suitable for transporting lubricating oil without solid particles and fibers, non-corrosive, temperature not higher than 120oC, viscosity of 5-1500cst or other liquids with similar properties to lubricating oil.
      It can be used as a transmission and booster pump in the oil delivery system. In the fuel system, it can be used as a fuel pump for delivery, pressurization and injection. In all industrial fields, it can be used as lubricating oil pump.
      The gear pump mainly consists of gear, shaft, pump body, pump cover, safety valve, shaft end seal and other components. The gear has high hardness and strength after heat treatment, and all the moving parts in the pump are lubricated by the medium it transports.
The pump has safety structural features:
        There are well-designed oil drain and oil return grooves in the pump, which minimize the torque force of the gears during work, so the bearing load is small, the wear is small, and the pump efficiency is high.
The pump is equipped with a safety valve for overload protection. However, it cannot be used as a pressure reducing valve for long-term work, and it can be installed separately in the pipeline if necessary. The valve acts as overload protection. However, it cannot be used as a pressure reducing valve for long-term work, and it can be installed separately in the pipeline if necessary.

        Fire pump, non-clogging sewage pump is a product with novel structure successfully developed on the basis of repeated research on the technology of similar products at home and abroad. The pump integrates self-priming and non-clogging sewage pumping. The pump body and the unique design of the impeller flow path, like general self-priming clean water pumps, do not need to install bottom valves and irrigation and diversion, and can also absorb and discharge large-particle solids and long-fiber impurities. Widely used in municipal sewage projects, river pond breeding manure treatment, sedimentation of waste ore impurities, light industry, papermaking, food, chemical, pharmaceutical, electric power, slurry and mixtures and other chemical media such as impurity pumps.
       The non-clogging sewage pump is a kind of pump product in which the pump and the motor are integrated and submerged into the liquid at the same time. Compared with the general horizontal pump or vertical sewage pump, the non-clogging sewage pump has the following advantages:
1. Compact structure, small footprint. The sewage pump can be installed directly in the sewage tank because it works submerged in the liquid. There is no need to build a special pump room to install the pump and machine, which can save a lot of land and infrastructure costs.
2. Easy installation and maintenance. Small sewage pumps can be installed freely, and large sewage pumps are generally equipped with automatic coupling devices for automatic installation, and installation and maintenance are quite convenient.
3. Long continuous operation time. Because the pump and the motor are coaxial, the shaft is short, and the rotating parts are light in weight, the load (radial) on the bearing is relatively small, and the service life of the sewage pump is much longer than that of ordinary pumps.
4. There is no problem of cavitation damage and water diversion. Especially the latter point brings great convenience to the operator.
5. Small vibration and noise, low motor temperature rise, no pollution to the environment.
