! WARNING

If pump is to be used on process fluids above 120°
F, pump surface temperatures could be warm
enough to cause burns. We recommend pump
surfaces be insulated. Failure to follow these
instructions could result in severe personal injury.
EXPLOSION PREVENTION
!
In order to reduce the possibility of accidental explosions in atmospheres containing explosive gases and/or dust, the
instructions under the ATEX symbol must be closely followed. ATEX certification is a specification enforced in
Europe for non- electrical and electrical equipment installed in Europe. The usefulness of the ATEX requirements is
not limited to Europe. They are useful guidelines for equipment installed in any potentially explosive environment.
SPECIAL ATEX CONSIDERATIONS
All installation and operation instructions in this manual
must be strictly adhered to. In addition, care must be taken
to ensure that the equipment is properly maintained. This
includes but is not limited to:
1. Monitoring the pump frame and liquid end
temperature.
2. Maintaining proper bearing lubrication.
3. Ensuring that the pump is operated in the intended
hydraulic range.
