Couple the pump and driver
WARNING:
Failure to disconnect and lock out driver power may result in serious physical injury or death.
Always disconnect and lock out power to the driver before performing any installation or
maintenance tasks.
• Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
• Refer to driver/coupling/gear manufacturer's installation and operation manuals (IOM) for
specific instructions and recommendations.
CAUTION:
• You must use a coupling guard made of a spark-resistant material in an ATEX classified
environment.
• Running a pump without safety devices exposes operators to risk of serious personal
injury or death. Never operate a unit unless appropriate safety devices (guards, etc.) are
properly installed.
Couplings must have proper certification to be used in an ATEX classified environment. Use
the instructions from the coupling manufacturer in order to lubricate and install the coupling.
Refer to driver/coupling/gear manufacturers IOM for specific instructions and recommenda-
tions.
Bearing lubrication
CAUTION:
•
Risk of explosive hazard and premature failure from sparks and heat generation.
Ensure bearings are properly lubricated prior to startup.
• Risk of heat generation, sparks and premature failure. Do not insulate bearing housings.
Lubricate the bearings with grease
Grease-lubricated pumps can be identified by grease fittings located on bearing housing.
Sufficient lubricant is inserted at the factory for 2,000 hours of operation. See the Maintenance
chapter for grease lubrication instructions.
Lubricate the bearings with oil (optional)
NOTICE:
• The bar must be adjusted as stated in this procedure. Otherwise, the bearing will not be
lubricated.
• Do not fill the oil reservoir of the bearing frame through the plug at the top.
Oil-lubricated pumps are not lubricated at factory. Use a high quality, turbine-type oil with rust
and oxidation inhibitors. Constant level oilers are supplied in the box of fittings that
accompanies most oil-lubricated pumps. Make oil adjustments before lubrication. See
Lubricating-oil requirements
(page 54) for recommended lubricants and supplies.
Bearing cooling is available with the oil lubrication option only. Cooling water must be
connected to the bearing housing with a waste or return line. Water cooling is required when
operating temperatures exceed 250°F (121°C).
