Operator Safety and  

Convenience Features

Safety Features

Although sump cleaners are inherently safe machines, 
they pose the potential for hand and finger injury 
when the operator removes the filter basket from the 
unit to empty it of chips and sludge. For this reason, 
Eriez HydroFlow has two safety features which are 
unique to their Sump Cleaners.
Filter basket safety guides automatically center  
the filter basket within the unit’s basket support  
tower as it is being hoisted out of the machine.  
This eliminates the need for the operator to physically 
guide the heavy, full basket as it is being elevated and 
significantly reduces the opportunity for the operator 
to receive hand injuries.
Basket “trapdoor” release cables enable the operator 
to empty the filter basket (the basket can hold up to 
800 pounds of chips) from a safe distance without 
the need for special tools. The basket is removed 
from the unit, positioned over a chip hopper or similar 
receptacle, and the contents are released through the 
basket bottom by the operator opening the trapdoor 
with a sharp pull on the release cable. During the 
entire operation, the operator is a safe distance away.

Convenience Features

Low rolling resistance, high maneuverability design: 
Sump Cleaners feature high impact, fiber reinforced, 
hard plastic casters and wheels for low rolling 
resistance, whether the unit is empty or full. The 
standard wheel configuration places the main wheels 
in the unit’s middle and swivel casters on each end 
for high maneuverability. A Sump Cleaner pivots 
within its own length while “tricycle gear” units swing 
in double their length.
Clamped basket lids make lid removal and 
replacement much faster and easier than it is with  
the screw clamps used on other makes of sump 
cleaners. Easy Lift Chip Basket Lid allows the lid to 
easily and safely lift up and out of the way to allow 
access to the chip basket.
External, leak-proof, round cleanout doors are faster 
and easier to remove and replace than the oval, 
internal “manholes” used by other manufacturers.  
The thick, pliable gasket bonded to the cleanout  
door virtually eliminates leaks.
Forklift truck brackets are standard on all “push-
around” Sump Cleaners so that the unit can be safely 
and easily picked up and moved long distances. 

17. This equipment is to be operated and maintained 

by authorized personnel only.

18. MAGNESIUM CHIPS OR DISSIMILAR METALS  

In the presence of water, magnesium can release 
highly flammable hydrogen gas. In the proper 
proportions with air, it can be explosive. When 
a Sump Cleaner is used on a metalworking 
fluid application generating magnesium chips, 
certain precautions must be taken to ensure 
that any hydrogen gas is dissipated into the 
atmosphere and to make sure the hydrogen 
does not accumulate in the Sump Cleaner.  
This is accomplished by promptly removing 
any magnesium chips from the sump cleaner 
basket. Also, a maintenance schedule should 
be established by the customer that would 
eliminate buildup of sludge in the bottom of 
the Sump Cleaner. Finally, the unit should be 
stored in a clean condition with basket empty of 
chips, the sump cleaner tower lid removed, the 
coolant discharge nozzle(s) removed, and hoses 
opened to the atmosphere (on single and twin 
compartment units). Taking these precautions  
will minimize the risk of hydrogen gas generation 
and accumulation. 
On an application where dissimilar metals are 
machined, there is a chance for spontaneous 
combustion to occur. Typically, metalworking 
facilities that machine various metals are aware 
of this and may have experienced problems in 
chip hoppers due to the presence of two or more 
metals, water, and tramp oil. 
The precautions mentioned in the previous 
paragraph will minimize or eliminate the potential 
for spontaneous combustion.

19. The cleaner is to be adjusted and/or repaired only 

by qualified service personnel. If these personnel 
need more information than is provided in this 
manual, they should contact Eriez HyrdroFlow
