In general, a pump is a machine for transporting a fluid through a pipe by using a pressure action, and there are largely a reciprocating pump, a rotary (rotary) pump, a centrifugal pump, an axial pump, a friction pump, and the fluid by the rotation of a double impeller. Centrifugal pumps for transporting are widely used in various fields.

In the centrifugal pump, an impeller having a plurality of blades rotates by driving of a motor, thereby sucking the fluid toward the central portion of the impeller and discharging the fluid to the side of the impeller. Of course, the impeller is installed in the pump housing, the pump housing is provided with an inlet through which the inflow is made and a discharge port through which the fluid is discharged.

On the other hand, when performing the manure collection operation by the manure car, when the septic tank is located deep underground, the manure can not be collected smoothly only by the pressure provided from the manure car, by connecting the manure car and the septic tank through a centrifugal pump Will do the work. As such, the centrifugal pump relaying the septic tank and the manure car sucks the manure sludge of the septic tank and transports it to the manure car, and the manure car collects the manure transported from the centrifugal pump.

Of course, the use of the centrifugal pump as a relay pump as described above is not limited to the manure collection operation, and the centrifugal pump is also used as a relay pump when transporting sewage sludge located deep underground.

As described above, in order to use the centrifugal pump as a relay pump, the centrifugal pump must be transported to an appropriate location underground.

However, since the conventional centrifugal pump cannot be transported at one time due to excessive weight, the pump is disassembled and moved by parts, and then reassembled to carry out the manure collection process. Therefore, the work is very cumbersome, and the parts are damaged during transportation. However, there is a high risk of loss, and moreover, there is a high risk of damage to the components during the assembly and disassembly is repeated.
