Sump Cleaner

7

Sump Cleaners have been designed to make the  
job of proper machine tool coolant sump cleaning  
as easy as possible for the operator of the sump 
cleaner. They have the power necessary for true, 
high-performance sump cleaning. They will vacuum 
from the sump anything that will pass through its two 
inch diameter suction hose and it will vacuum up 
water soluble coolant at nearly 100 gallons per 
minute. At the same time, all Sump Cleaners are 
designed with operator safety and ease of operation 
and maintenance as foremost considerations.
Although the units are designed for operator safety, 
before using the sump cleaner for the first time (and 
periodically thereafter for a review), read the section 
of this Operator’s Manual entitled “Safety 
Information”, pages 3-4. 

Operating Efficiency Tips

Here are some tips to improve the operating 
efficiency of your sump cleaner:
•  Follow the sump cleaner’s maintenance schedule  
 

carefully. Preventive maintenance is much less  

expensive than major repairs.

•  Clean your sump cleaner (or just the filter  
 

tank of a twin compartment unit) once a month  

or whenever sludge or fines have become  

noticeable in the bottom of the tank.

•  Rinse the unit with plain water and drain it  
 

completely by removing the drain plug whenever  

changing from one brand or type of coolant to  

another. There can be compatibility problems  

with some products, so avoid contamination.  

(Remember to replace the plug.)

•  It is better to have one sump cleaner for use  
 

with water soluble coolants and another for use  

with cutting oils. If you must use one unit for both,  

the sump cleaner must be thoroughly cleaned  

when switching products. If at all possible,  

purchase a filter basket and a set of hoses for  

each product. (The sump cleaner tank is not too  

hard to clean, but the hoses and filter basket are.)  

Organize your machine pumping schedule so that  

during one week you are pumping machines  

running water solubles and the next week you  

are pumping machines running cutting oils.  

This minimizes cleaning the sump cleaner.

Operating Tips

•  When vacuuming out the machine, put the  
 

cleaning tool on the bottom of the sump and  

remove coolant and chips together.

•  If heavy, deep sludge is in the machine sump (cast  
 

iron applications), remove the majority of liquid.   

Take the cleaning tool and mix the remaining liquid  

with the sludge and then vacuum this mixture out.

•

  Do NOT alter the unit’s vacuum relief valve  

 settings.

 You will not improve your sump cleaner’s  

performance and you will void its warranty.

•

  Do NOT use your unit for solvents, volatile or  

low flash point fluids of any type.

 It is designed  

for use with coolants, cutting oils, water soluble  

machine cleaning solutions and parts washing  

compounds only.

•  When pumping out of floor pits you can increase  
 

the efficiency by drilling a 1/4" hole in the cleaning  

tool below where the hose is attached. By keeping  

this hole above the fluid level, you allow more air  

to enter the hose which helps move the fluid up  

the hose faster and possibly allow pumping out  

of deeper pits.
