5HP INLINE PUMP MANUAL REV030921 

2.

 

Connect main feed line to check valve. Pump 

MUST 

have a check valve installed inline to tank. This helps to 

prevent the pump from starting underload. This also prevents air loss and premature pump wear. Minimum line 
ID size for main line 

is 5/8”. This can 

be flexible or solid. 

DO NOT

 install the unit with a shut off valve anywhere 

in the main feed line. This could lead to serious injury or death. 

Output threads are ¾” FNPT.

 

3.

 

Pressure lubed pumps 

DO NOT

 have built in unloaders and require a separate relief valve. This will relieve head 

pressure once the pump stops and provide no-load restarting. 

4.

 

Cylinder heads are equipped with continuous run lines. If the lines are not to be used, please cap input side. 
Lines on the head are for input from a manufacturer approved pilot valve only. 

DO NOT 

run lines from relief 

valve or unregulated lines from the tank to this system. 

 

5.

 

Use proper pulley for motor size and RPM. 

DO NOT 

exceed pump maximum recommended RPM. Exceeding 

pump RPM will cause premature wear/damage to the pump and will void pump warranty.

7.

 

This model 

of pump requires the use of two, ‘B’ groove belts. 

 

8.

 

Rotation of the pump should be clockwise when facing the pressure gauge, or counterclockwise from the 
flywheel side. 

9.

 

Use care when aligning pump flywheel and motor pulley. Ensure center ridge on pump and pulley are in line. 
Any direction out of line will cause premature belt wear. 

10.

 

When tightening belts check for belt deflection. Deflection should be no more than ½ inch. 

  

 

 

 

 

Input lines for continuous run set up only. 

DO 

NOT 

run lines from other sources to these 

locations. Use only a manufacturer approved 
pilot valve for continuous run use. 

Proper belt tension is determined by pressing midway between the 
motor pulley and the pump flywheel.
