Installation Guide
Pumps may be installed in a horizontal or vertical position for optimum functioning of
suction and delivery valves. The round reservoir may be used horizontally and it is
advised that the breather and sight glass be interchanged and/or the reservoir rotated
to allow the breather to remain uppermost. The suction and return tubes inside the
reservoir may also be rotated to ensure fluid is taken from, and returned to, the bottom
of the reservoir in any given position.
The air inlet connection can be rotated at 90 º and piping of not less than 3/8” bore
should be used. 1/2” should be used if the pump is to be run at higher speeds for
greater flows.
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
•
Room temperature 40º F to 100º F
Obstructive icing of the silencer may occur under certain temperature/humidity
conditions. This can be remedied by the addition of antifreeze oil for pneumatic
equipment to a mist lubricator.
Compressed Air System
It will be advisable to fit an air filter/regulator unit having minimum flow capacity of 50
scfm with an air pressure gauge to ensure the pump has sufficient air energy to work
correctly and provide the hydraulic performance you expect.
Hydraulic System
Valves, pipes, hoses and accessories should all correspond to maximum working
pressure of the pump used and be of a size that will fulfill flow requirements.
