Sump Shark sump cleaning pumping performance is determined by two main factors: suction lift & CFM (cubic feet per minute). The suction lift allows for depth and the CFM allows for speed of movement. Sump cleaners have to balance between the amount of CFM versus the need for nozzle velocity.
amount of sludge and end user labor cost.
The suction lift determines the depth and the viscosity of sludge that can be suctioned through a given hose at a certain depth. The more suction lift you have the more sludge you can suction at a greater depth. You can fill a filter to a higher capacity with greater suction lift.
The diameter of the hose determines the speed at which the fluid and sludge will move through the hose. The larger the hose the more fluid that can be suctioned at one time. The negative to a larger hose is three fold:
- Maneuvering into smaller areas in a sump
- Handling a larger diameter hose while picking up sludge
- Removing fluid faster than you can remove sludge
The last part of the equation is the labor time spent cleaning a sump.
The quicker the liquid is suctioned off the less time the solids will have to be removed from the sump. If the liquid is removed too quickly then you will have to refill the sump and repeat the process to get all of the sludge or use the old fashioned pail and shovel approach to get the job done right.
With the CECOR Sump Shark the suction/discharge are more controlled by the diameter of the hose then anything else. Over time we have determined that 1-1/2″ suction/discharge hose is most efficient when the sump is less than 200 gallons. To clean a sump right you right you need to drag the right tool on the bottom of the sump to allow both fluid and sludge to be suctioned up at the same time.
CECOR’s has worked with many customers over the years to determine the right balance between suction speed, discharge speed and amount of labor required to clean a sump right. The Sump Sharks have this balance build into every sump cleaner. We use a 1-1/2″ hose to decrease the suction speed slightly and increase the amount of time the person cleaning the sump has to get more sludge out of the machine tool sump pit during the first pass.
CECOR’s has produced three tools that work hand and glove with our 1-1/2″ diameter hose. Our Sump Shark is designed to make it very easy for the user get the sump cleaned properly quickly, safely and efficiently. CECOR Sump Shark sump cleaners allow you to use suction and discharge at roughly the same rate. Our customers have found they can switch to discharge in about 10 seconds and use the discharge mode to wash down higher areas of the sump down with enough force to move even the toughest sludge into the main sump pit area. Then switching back to suction they can complete the sump cleaning process.
