Installation
Notice: Re-torque fasteners prior to use. Refer to torque requirement listed in maintenance
manual and attached to pump.
1. A lube-free, clean, dry, compressed air source (or any nonflammable, compressed gas) is
recommended. Use a filter that is capable of filtering out particles larger than 50 microns.
2. All pumps should be mounted in an upright position with the exception of the ¼” models
which may be rotated 360° to suit the application.
3. When particles exceed the maximum particle specification of the pump or are sharp enough
to cut elastomers install a particle fluid filter on the fluid suction line.
4. Fluid suctions lines and air exhaust lines should never be smaller than specified pipe size of
pump.
5. Apply Teflon tape to threads upon assembly to prevent leakage.
6. Never use pipe dope on air line connections.
7. Never use collapsible tube on fluid inlet.
8. Do not exceed 14 Nm of torque on plastic pipe threads.
9. If changing to a different application reconfirm compatibility of fluid.
Submerge applications
1. Fluid must be compatible with fasteners and with intermediate material.
2. Pipe exhaust above the level of the fluid.
High viscosity applications
1. Position the pump close to or below the level of the fluid source.
2. Suction lines should be increased in size – up to three times the size of the inlet manifold.
Dual manifolds may be used when available.
3. Start the pump slowly using a valve on the air line.
Low temperature and UV exposure
1. Polypropylene tends to embrittle at freezing temperature. Pump must be insulated or heated,
otherwise use pumps with different materials of construction.
2. If excessive icing occurs at the pump exhaust, air source must be dried using mechanical
means or through the introduction of ethyl alcohol in the air line.
3. UV rays will damage polypropylene pumps, either shroud the pumps from UV rays or use
pumps with UV stabilized materials.
