Significantly reduces the clogging, plugging and entangling of fibrous debris that would clog most competing pumps, allowing for less downtime and lower maintenance costs.

Note:Obstacle pass-through may vary with flow rates.

The vertical mounting design allows for easier and more

efficient inspection and part replacement.

The pump unit can be detached without removing the impeller

from the motor.
