Graco 260022 Manual De Usuario

All pump models should prime within 5 seconds after 
pump is turned on up to a height of 36 in. (91 mm). 
Pumps installed at height up to 5 ft. (1.52 m) may have 
difficulty priming. Follow procedure below to initiate 
prime. Pumps installed at suction height above 5 ft. 
(1.52 m) will have difficulty in holding prime. It is recom-
mended that check valve (Graco part no. 260217) be 
added to the bottom of the suction tube to help maintain 
prime.

If prime in not achieved in 30 seconds after turning the 
pump on use the following procedure to initiate prime;

1. Remove 90° Union Swivel (15) from ¾” Inlet Nipple 

(14).

2. Pour fluid being pumped into pump outlet until com-

pletely filled. 

3. Re-assemble Union Swivel (15) back onto nipple 

(14). Turn pump on. The pump should gain prime in 
under 5 seconds.

4. If pump still does not gain prime check for any major 

leaks in the system. If no leaks are found then the 
pump is mechanically defective and should be 
reported to Graco Product Service for disposition.

It is important that the swivel end of the 90° union 
swivel (15) is assembled to the ¾” outlet nipple (14) 
for proper sealing (see fig. 6). Also, if the pump has 
difficulty priming it is easy to remove the swivel and 
pour fluid into the pump outlet cavity when assem-
bled this way.

1. First make sure there are no fluid leaks from the 

pump outlet out to the fuel nozzle. Any leaks after 
the outlet will allow air to push the fluid column back 
to the tank and prime will be lost.

2. If no leaks are detected on the outlet side of the 

pump, remove the pump from the tank and inspect 
the suction tube and pump inlet for leaks. 

3. If the system is leak free and the suction height 

guidelines are followed the pumping system should 
not lose prime.

On/Off switch lever (8d) is located under nozzle holder. 
Remove nozzle before turning pump on.

1. Move switch lever (8d) on.

2. Insert nozzle into tank and actuate nozzle lever to 

dispense fuel.

3. Immediately after fueling turn switch lever (8d) off.

1. Clean inlet strainer (3b) after every 50 hours of 

operation.

2. To remove inlet strainer (3b), remove four screws 

(3c) and strainer cover (3a). Remove and clean 
strainer.

3. If strainer is excessively dirty, clean tank to protect 

pump and the equipment being fueled.

4. After cleaning strainer, replace strainer and cover. 

Make sure cover seal (3d/7e) is in place.

All guidelines and procedures are based on pump-
ing diesel fuel. If pumping gasoline priming may be 
more difficult due to the lift of gasoline dependent 
on Reid's vapor pressure of the gasoline and it's 
temperature. The lower the vapor pressure and 
temperature, the higher the possible lift. 

Before servicing, turn pump off and open the 
nozzle to relieve pressure.

Do not operate pump dry. Do not run pump for more 
than 5 minutes with nozzle closed. Do not operate 
pump for more than 30 minutes continuously in 1 hour.
