1.  Use  a  pressure  relief  device  on  the  discharge  side  of  the 

pump  to  prevent  damage  from  pressure  buildup  when  the 

pump discharge is blocked or otherwise closed and the pow-

er source is still running. 

2. 

WARNING:

 Never pump flammable or explosive fluids such 

as  gasoline,  fuel  oil,  kerosene,  etc.  Never  use  in  explosive 

atmospheres.  The  pump  should  be  used  only  with  liquids 

compatible  with  the  pump  component  materials.  Failure  to 

follow this warning can result in personal injury and/or prop-

erty damage and will void the product warranty. 

3.  Never pump acids (i.e. acid fertilizer) with Super Rollers!  

4.  Never  run  the  pump  faster  than  maximum  recommended 

speed. 

5.  Never pump at pressures higher than the maximum recom-

mended pressure. 

6.  Never pump liquids at temperatures higher than the recom-

mended maximum temperatures (140°F/60°C). 

7.  Make certain that the power source conforms to the require-

ments of your equipment. 

8.  Provide adequate protection in guarding around the moving 

parts such as the shaft and pulleys. 

Roller Pump General Safety Information 

9.  Disconnect power before servicing. 

10.  Release all pressure within the system before servicing any 

component. 

11.  Drain all liquids from the system before servicing any com-

ponent. 

12.  Check all hoses for weak or worn condition before each use. 

Make certain that all connections are tight and secure. 

13.  Periodically inspect the pump  and the system components. 

Perform routine maintenance as required. 

14.  Never  operate  a  gasoline  engine  in  an  enclosed  area.  Be 

sure the area is well ventilated. 

15.  Use only  pipe, hose and fittings rated for the maximum  psi 

rating of the pump. 

16.  Never  use  pump  for  pumping  water  or  other  liquids  for  hu-

man or animal consumption. 

 

WARNING:  Never  pump  corrosive  or  abrasive  liquids  as  these 

will cause rapid wear or deterioration of the body, rotor, shaft and 

seals  in  the  pump.  The  pump  should  be  used  on  with  liquids 

compatible with pump component materials. Never exceed maxi-

mum specified rpm and pressure. Never run pump dry. Failure to 

follow this warning will void the product warranty. 

 

Priming the Pump: 

To help prime the pump, keep the inlet or suction line as short as 

possible with a minimum of bends, elbows and kinks. Make sure 

all  connections  are  tight  and  do  not  leak  air.  Make  sure  line 

strainer is free of debris. If pump does not self-prime, disconnect 

suction hose, fill with water and reconnect to liquid source. Often 

a squirt of oil into the ports of the pump will seal clearance and 

help priming. 

 

Care of the Pump: 

Proper  care  and  maintenance  will  keep  your  pump  wear  at  a 

minimum and will keep it running smoothly and trouble-free for a 

long time. 

Roller Pump Operation & Maintenance 

Flush the Pump After Each Use 

One  of  the  common  causes  of  faulty  pump  performance  is 

“gumming”  or  corrosion  inside  the  pump.  This  prevents 

rollers  from  moving  freely  in  their  rotor  slots.  Flush  the 

pump with a solution that will neutralize liquid pumped, mix 

according to manufacturer’s directions. 

 

To Prevent Corrosion: 

After  cleaning  pump  as  above,  flush  it  with  a  50-50  solution  of 

permanent-type automotive antifreeze (containing a rust inhibitor) 

and water. A rust inhibitor can also be squirted into the ports of 

the  pump.  Turn  shaft  several  times  to  draw  protective  liquid 

through  pump  and  coat  entire  inner  surface.  Drain  pump  and 

plug  ports  to  keep  out  air  during  storage.  For  short  periods  of 

idleness,  noncorrosive  liquids  may  be  left  in  the  pump,  but  air 

must be kept out. Plug ports or seal port connections. 

Symptom

Probable Cause(s)

Corrective Action

Check hose and fittings for leaks and correct

Obstruction in suction line

Inspect hose for debris or loose inner liner in hose

Suction hose sucked to
bottom or side of tank

Cut a notch or "V" in end of suction hose

Rollers stuck in pump

Disassemble pump and inspect rollers

Pump seals leaking air

Replace seals
