6. MAINTENANCE AND

SERVICE

6.1 General Introduction

SPP Pumps AUTOPRIME pumps will
provide many years of trouble free service
when maintained in accordance with these
instructions. In the event of failure of the
pump it is recommended that SPP Pumps

Ltd. Service Department is called to
investigate and carry out repairs. The
following instructions are given to cover the
main elements of strip and rebuild but do
NOT include instructions for work that
MUST be done by an SPP Pumps Ltd.
Service Engineer.


The following hazards may arise during
maintenance work:

Fluid Pressure Jet Hazards
Check and ensure that the pump operates
at below the Maximum Working Pressure
specified in the manual or on the pump
nameplate and before maintenance, ensure
that the pump is drained down.

Hazardous Materials
Wear a suitable mask or respirator when
working

with

Gasket

components which contain fibrous material
as these can be hazardous when the
fibrous dust is inhaled. Be cautious, if other
supplier's

components

have

been

substituted for genuine SPP Pumps parts,
these

may

then

contain

hazardous

materials.

Hazardous Gases, Mists, Sprays and
Leaks
