Description and Start Up Procedures
Pumps must be installed in a horizontal position. Be sure that suction lines from the
manifold to the hydraulic fluid are as straight as possible and do not have high
points to trap air. Suction lines should be at least ¼” inside diameter and steps
should be taken to ensure the hydraulic fluid is kept commercially clean. The air inlet
connection should have piping of at least 1/8” bore and be kept to the shortest
length possible to keep pressure losses to a minimum.
These operations should be
carried out by qualified personnel.
It is advisable to use or maintain:
Hydraulic oil having viscosity of 150 to 250 SSU
Oil temperature 32º F to 150º F
Air temperature 40º F to 100º F
Compressed Air System
It will be advisable to fit an air filter/regulator unit having maximum flow capacity of
at least 5 scfm. Use tubing of at least ¼” inside diameter to avoid pressure losses.
Hydraulic System
Valves, pipes, hoses and accessories should all correspond to maximum working
pressure of the pump in order to ensure the
safety of all persons
nearby.
Components should always be of a size that will fulfill flow requirements without
unnecessary pressure losses.
Priming and Initial Operation
After connecting the pump to air and oil circuitry, loosen the first hydraulic
connection to allow entrapped air to bleed out. Allow the pump to operate with 20
PSI air pressure until the oil flows from the loose joint and then tighten the joint.
Always observe strict safety and protection during this operation. Adjust settings until
smooth operation is achieved.
