Operating personnel should know that any changes in the system or the liquid being pumped might have an effect on the pump’s
performance. It is advisable to also record the fluid temperature, specific gravity, viscosity, liquid concentration, percent of solid con-
centration, other additives and properties. A proper maintenance procedure should begin with a file for each pump. All known data
relative to the pump, fluid handled and system should be included. Complete records of maintenance and repair costs along with a
log of the units operating hours should be kept.
In addition, complete pump identification- size, type, operating speed, manufacturer, serial number, model number, and material of
construction should be noted.
Maintenance Procedures
Daily Check – possibly the most important inspection will be the daily observation.
1. Seal leakage rate
2. Pressure reading and flow indication
3. Change in operating sound
4. Change in bearing temperature
5. Check to make sure flow is going through the double seal flush lines (for Double Seal pumps)
Semi-Annual Inspection – typically made at 6-month intervals with results noted in the pumps maintenance file.
1. Check of mechanical seal assembly
2. Check of bearing lubrication
Annual Inspection – includes Semi-Annual inspection plus:
1. Removal of seal for inspection
2. Bearing
check
3. Check of axis/running clearance of impeller
Contingency Plan
For inspection findings and breakdowns, a contingency plan should be developed. To begin, an adequate supply of probable replace-
ment parts should be kept on hand.
The minimum recommended spare parts are as follows:
1. Mechanical seal kit (complete with O-ring set)
2. Casing
O-ring
3. Impeller
key
In addition Ampco recommends
1. Impeller
2. Impeller nut / bolt and washer (SP 240 only)
Where service cannot be interrupted, a complete stand-by pump
unit fully assembled (and in a by-pass line) is recommended.

DISMANTLE AND REPLACE PARTS AS FOLLOWS:
Before attempting any service on the pump or motor, discon-
nect or lock out electrical power to the pump motor. If the pump
and motor are to be removed as a unit, note the wiring configu-
ration. Use colored or numbered tape to mark the wire connec-
tions of the motor and power source, for reconnection.
These instructions are limited to fluid ends only; see other
drawings and literature applicable to motors, pedestals, frames,
shafts, etc. if additional repairs are required.
