X9 Series metering pumps
Since the machine object of supply is a product designed and intended for operation in industrial areas, additional measures must
be adopted and assured by the person responsible for the installation, should more restrictive safety conditions be
required.
All maintenance work must be carried out on the pump only when the machine is stopped and
disconnected from mains supply (including auxiliary circuits). Maintaining original characteristics over time must be
ensured by an efficient maintenance and inspection plan, developed and managed by qualified technicians, taking into
GB
account the service and the actual environmental conditions in which it operates.
7.2

CONSULTING TECHNICAL DOCUMENTATION

Before starting work, you should consult again this use and maintenance manual, identify the correct sectional drawing of the pump in
use and get all the tools and equipment necessary to perform the maintenance or repair works.
NOTE: When the pump has been disassembled, waiting to be reassembled, it is necessary to protect the various components
(particularly those inside the mechanism, paying special attention to the working surfaces of the seals) to prevent damage caused by
oxidation or accidental impact.
Improper assembly of the sealing components or ball bearings can anticipate their deterioration and result in
malfunction and/or overheating.
7.3

PERIODIC OPERATIONS

As a general rule, after the first start-up, close initial monitoring of the machine is recommended to practically define the maintenance
plan and also determine the frequency of general inspections and planned maintenance.
Should anomalies or malfunctions occur it is user's responsibility to consider whether maintenance work should be anticipated or not.
7.3.1

Checks of normal operation

During periodic inspections, verify that:
there is no leakage of handled fluid, lubricating or hydraulic oil
-
the pump operates properly, without abnormal noises or vibrations
-
CE protections (accident prevention) are always fitted
-
Any defects or irregularities detected during inspection must be promptly solved !
7.3.2

Checks of electrical connections

Power cables, control and grounding cables must not have signs of deterioration and connections must be tight.
7.3.3

Checks of pump connection to plant pipeline

Verify that the connection elements (screws, nuts and bolts, flanges, etc.) are firmly tightened and that relative sealing components are
efficient and in perfect condition. During normal operation, pumps can transmit vibrations to pipelines, loosening component
connections and causing product leakages. In this case, install a pulsation dampener to reduce pressure peaks, making flow linear and
reducing these vibrations.
7.3.4

General and surface cleaning

It is suggested periodically perform the following operations:
if the pump works in a batch dosing system, and the handled fluid tends to coagulate, solidify or crystallize easily, wash the
a)
pumphead immediately after each working cycle
b) prevent/eliminate surface deposits of material that can generate scale and encrustations
c) remove any accidental presence of corrosive product from the external surface of the pump
d) verify and be sure that motor ventilation is not impeded. Remove any possible deposits of dust or fibres from the fins and fan
cover.
7.3.5

Protection against corrosion

Dosing of aggressive chemicals or operating in exposed environments (acid atmosphere) may expose the pump to corrosion and the
risk of premature wear of sealing components. Periodically check:
a) that protection covers are always mounted
b) that operating windows are always properly closed
c) that there is no oil contamination in the reduction gear that could endanger proper lubrication.
