38 6EM Thru 18GM - 1100 Vertical Turbine Pumps
SECTION 5 MAINTENANCE
Preventive Maintenance
To assure satisfactory operation of the
pump, scheduled inspection and periodic
maintenance are required. We suggest an
inspection and maintenance log be kept and
the inspector immediately report any
problems.
This Layne/Verti-Line model 1100 vertical
turbine pump is supplied with product
lubricated column and bowl bearings. The
suction bell bearing is grease packed at the
factory. It is not necessary to re-lubricate
this bearing except when the pump is to be
torn down for maintenance and the bowl
assembly is to be disassembled.
A guide for preventive maintenance for
normal applications is given below. Unusual
applications with abnormal heat, moisture,
dust, etc., may require more frequent
inspection and service.
