PI Operation Manual
These units are vertical process pumps of the overhung configuration and identified by WDM
Pumps as PI.
It is recommended that the services of a WDM Pumps installation technician be employed for
the installation and initial starting of the pump. Such service will help to ensure the user that the
equipment is properly installed, and will provide an excellent opportunity for the plant operator to
receive useful tips and guidelines relative to the unit. The tools and/or equipment referenced in
this manual are not supplied by WDM Pumps unless specifically ordered. This pump design can
be serviced with standard maintenance tools.
Instructions in this manual are written for trained, experienced technicians who are familiar with the
basic principles and tools involved in the installation, care and service of a pump and who, as part
of their trade education have acquired the ability to interpret and follow the detailed specifications
required for such installation, care, and service. Successful operation of the unit is dependent on
careful study of the manual and a well-planned maintenance program.
A complete reading of this manual by personnel in contact with the pump is essential to safety.
Incorrect installation, operation or maintenance can result in personal injury or death to personnel
and damage to the pump and plant.
Before performing any service function be certain that the unit is separate from its power source
or that the power source is locked out to prevent any form of energy from entering the equipment.
Contact with hot surfaces of the pump can cause severe burns. Care must be taken where such
surfaces are exposed. Care must also be taken to prevent ignition of flammable fluids or other
material.
Information in this manual is believed to be reliable, but it is not guaranteed by WDM Pumps as to
