is reached before pump has primed. Measure liquid temperature and
modify alarm and stop trips settings accordingly.
Theoritically the pump could prime up to 8 meters but lifting height
will be limited to 6 meters to take suction line head losses into
account.

Priming time depends on lifting height, length of the suction line, inner
diameter of suction pipe and specific gravity of the fluid.
It will be necessary to apply correction factors to know priming time :
Tt = table with Ha = Hg x d
Ta = Tt x L/Hg x (DT/DN)²
With :
Tt : theoretical priming time
Ha : suction height with specific gravity correction factor
d : Specific gravity of fluid
L : total length of suction line
DT : inner diameter of suction pipe
DN : pump suction flange nominal diameter

9 MAINTENANCE
9.1 GENERAL INFORMATION
Only properly trained and skilled staff should undertake
maintenance operations.
Only authorized personnel should undertake maintenance on
ATEX certified equipments. Make sure to avoid creation of
explosion hazard while proceeding to maintenance in a ATEX zone.
All technical documents delivered with the pump should be known
and should be available near the pump.
The maintenance crew should be informed about the risks linked to the
use of the pump and to the pumped fluids before they can start working
on the equipment (dangerous products, fluid and pump temperature,
6
pressurized parts, ...). They should be equipped with all appropriated
individual safety protections (glasses, gloves, ...) and should respect local
industrial and security rules.
62
Pump contains a part of pumped fluid even when it is at a
34
standstill. Drain and flush pump casing with care before starting
pump disassembly.
155
77
Appropriate lifting devices should be available to help personnel moving
41
heavy loads.
33
The maintenance area must be clearly identified. Install warning boards
38
with the words « WARNING : machine under repair ! » on the pump and
95
on the control cabinet.
39
Any work on the machine must be performed when pump is
stopped. Prior to any maintenance or repair work the motor
26
should be electrically isolated and secured against uncontrolled start.
20
Lock the main switch open and disconnect circuit breaker. Withdraw the
54
fuses if any.
25 WARNING : electrical equipments that must be powered on during the
maintenance work or pressurized equipments must be clearly identified.
27
End of maintenance operations : all protective parts that were removed
95
before maintenance should be reinstalled and all security devices should
be reactivated. Pump surrounding area should be cleaned.

9.2 MAINTENANCE
INSPECTIONS SCHEDULE
It is recommended to build up a maintenance and inspection plan
to ensure a reliable use of pump and to reduce malfunctions
hazards. Following check points should be included in this maintenance
plan :
 Check state and working of securities and auxiliary systems,
 Check and adjust gland packing (if any) for visible leakage,
 Check for any leaks from pump gaskets and flanges seals,
 Check lubricant level and aspect of oil (oil lubricated bearings) in
bearing bracket,
 Check running time and replacement frequency of lubricants / ball
bearings,
 Check the bearing bracket housing surface temperature on ball
bearings area,
 Check dirt and dust is removed from pump and motor ,
 Check coupling alignment (depending on pump variant),
 Check if there is unusual noises (cavitations, hissing, purring, ...) or
excessive vibrations.
