MAINTENANCE

4.1

ROUTINE MAINTENANCE

This section gives details of routine preventative maintenance. Where repair or major overhaul is required
please contact PEERLESS PUMP COMPANY SERVICE.

4.1.1 GENERAL

Routine maintenance is essential to maintain the plant in a serviceable condition, and a sound
insurance against enforced inopportune shutdown.

A high degree of cleanliness of equipment and surrounding areas should be maintained during all
maintenance procedures.

4.1.2 FREQUENCY OF INSPECTIONS

A general guide is shown in Table 3.

Depending on operation and environmental conditions together with a comparison of previous
inspections, the frequency may be altered to maintain satisfactory operation of the plant to suit
established operating procedures.

4.2

LUBRICATION

GREASE LUBRICATED BEARINGS

Bearings are initially lubricated during manufacture or re-assembly. The re-greasing interval depends upon
the running speed of the unit:

TABLE 3

BEARING RE-GREASING INTERVALS

PUMP RUNNING SPEED

RE-GREASING INTERVAL

AMOUNT OF GREASE

1450/1750 RPM

5000 HOURS

2 OUNCES

2950/3550 RPM

3000 HOURS

2 OUNCES

To recharge the bearings with fresh grease, use a grease gun through the two lubricating nipples provided.

DO NOT APPLY LUBRICANT WHEN PUMP IS RUNNING.

Every 10,000 hours or 2 years, remove bearings from pump, de-grease, thoroughly clean, recharge with
fresh grease and refit in accordance with re-assembly instruction;
