1. The working position is different. The sump pump (vertical slurry pump) is partially immersed into the pit pool and cannot be completely immersed in the liquid surface. The submersible slurry pump can be completely immersed below the liquid level (including the motor part);
2. The motor of the sump pump (vertical slurry pump) can use an ordinary vertical motor, no need to waterproof, and the motor shaft and pump shaft of the submersible slurry pump are coaxial, the motor must be waterproof and sealed, and the motor and pump can be immersed in the liquid at the same time. The submersible slurry pump is an emerging product newly developed according to market demand;
3. In practical applications, the vertical slurry pump needs to be fixedly installed when work, and the submersible slurry pump could move easily.
