The Function of Each Tank
The combination sump cleaner/coolant dispenser consists of two separate tanks on a single chassis. One tank is a sump cleaner; the other a dispenser. CECOR Combination Sump Sharks are most often part of a central coolant recycling program. These units are designed to work in tandem with a central recycler or coalescer.
The side with the filter is the sump cleaner side. This side is also called the dirty pick up tank because it is where the dirty metalworking fluid and sludge goes when it is vacuumed from the machine tool.
The sump cleaner or dirty pick up tank side has two functions:
- Clean machine tool sumps. Dirty metalworking fluid and sludge are sucked through the hose in the top of the tank where it passes through a filter. The filter catches solids and filtered fluid flows into the tank.
- Pumps filtered coolant out of the sump cleaner tank. The filtered coolant is pumped back through the discharge into the machine tool, transported to central recycling system or to the fluid waste area of the plant.
The side without the filter is the dispenser side. It is also called the clean delivery tank. This tank dispenses fresh or recycled coolant to the machine tool. It can be filled using the on-board pump or through the fill hatch.
The dispenser or clean delivery tank side has two functions:
- Carry fresh coolant or recycled coolant from a recycler to the machine tool.
- Dispense coolant. Coolant is pumped out through the clean tank dispenser hose.
The Sump Cleaner Side
Vacuum pump creates a vacuum in the sump cleaner tank. The vacuum pulls in the sump contents. As fluid and solids flow through the hose into the suction intake port, the solids are caught in the filter while the fluid continues into the tank.
The Dispenser Side
When pump is switched to discharge, a low pressure develops in the tank that forces the filtered fluid up through the discharge port.
Vacuum pump creates a vacuum in the dispenser or clean tank. The vacuum pulls in new coolant or coolant from central recycler for transporting to machine tool. The dispenser side can also be filled through the fill hatch at the top of the tank. When pump is switched to discharge, a low pressure develops in the tank that forces the filtered fluid up through the discharge port.
Role in Coolant Recycling Systems
CECOR Combination Sump Shark/Dispenser units work well with coolant recycling systems by filtering chips and sludge from coolant prior to transporting to central coolant recycler. Use dispenser side to transport treated coolant back to machine tool sump.
