CARE AND PREVENTIVE MAINTENANCE
The most critical part of the pump is the seal. This is because the
seal is subject to wear, particularly when the pump is handling
abrasive materials. It is important that the seals and the sleeve are
replaced before they have worn excessively. If the seals and sleeve
are allowed to wear until failure occurs water will enter the spindle
bearings.
Noisy bearings will not be apparent due to the noise level from the
drive motor.
If the pump is operated unchecked in this condition water will
eventually enter the flexshaft. Naturally, the cost of repairing, a
pump which has been allowed to deteriorate in this way will be
greater.
Regular inspection of the pump and the seal will avoid these
problems.
Check the 3-tooth dog on the drive coupling to ensure that it is fully
meshed and not worn.
Check the strainer for missing sections that could allow the entry of
large objects and result in damage or obstruct ion of the impeller or
volute.
Dismantle the pump and the flexible shaft every 500 hours.
Inspect for wear and lubricate before reassembling
Apply a liberal quantity of grease to the core assembly when
inserting it into the casing assembly from the drive coupling end.
If the spindle is worn by the seal/s located in the adaptor and it is
otherwise satisfactory for further use do not remove the existing
worn seal/s from the screwed adaptor. The bore of the adaptor is
deep enough to accommodate additional seal/s which will then be
located on an unworn area of the spindle.
Check the flexible shaft for kinks and external damage by laying it
out straight on a workbench or the floor. Although it still operates a
badly kinked flexible shaft may result in a broken inner core.
CLEANING AND STORAGE
It is advisable to operate the pump in clean water after use each
day or before storing when it has been used in sludge or water with
a high solid content. This will ensure that mud and sludge do not
dry out and obstruct the body or the impeller.
The three eye nuts can be unscrewed to allow removal of the pump
body and access to the impeller.
Hire operators should check the impeller for rags, solidified mud
and debris after each hire. While the body is removed check the
spindle bearings for slackness and smooth rotation.

SERVICE
! CAUTION
Read the operating instructions before servicing this product
and note the safety information.
Exercise care when handling flexible shaft casings. Severe wear
or damage to the rubber cover may allow the internal wire braid
to protrude and cause injury.
Exercise care when handling pump impellers. Extreme wear may
result in thin sections or sharp surfaces and cause injury.
