The Raptor series of pumps are designed for long periods of trouble free operation.
The frequency of service inspections is determined by the operating conditions
which the pump is operating in.
As a minimum the following inspections should be made every six (6) months, however
site maintenance staff should set inspection intervals based on the operating conditions
which the pumps are operating in.
Note that a drop in output capacity or changes in operating current are an indication
that the pump is in need of inspection.
Ensure all in inspection work is performed by suitably qualified and trained
persons.
Inspect the electrical power cable for damage and replace as necessary.
Measure the insulation resistance of the power cable and motor
windings. If the winding resistance is not correct then remove the
cable and measure the resistance of the windings only. If this reading returns
to normal replace the cable. If the reading does not return to normal the pump
should be sent to a PumpEng dealership for repairs.
Visually inspect all external components of the pump and replace any damaged
components.
Ensure that the cooling jacket internal waterways are free of obstruction, flush/clear
as required.
Check that all nuts, bolts and screws are secure. Remove the oil inspection
screws. (Danger this area may be under pressure, take appropriate
precautions) Lay the pump on its side and pour oil into a suitable container,
check the condition of the lower bearing housing oil. If there is any indication of
contaminates in the oil then it is possible that the mechanical seals
or bearing housing o-rings have failed and as such the pump
should be sent to a PumpEng dealership for repairs. If the oil is not
contaminated replace with new oil (quantity required is 1.4 Liters) ensuring
that the inspection screw o-rings are replaced and the inspection screws are
tightened to 15 Nm.
Remove the stator inspection screw. (Danger this area may be under pressure,
take appropriate precautions) lay the pump on its side and check if there is
any water or oil in the stator casing. If evidence of oil or water are present it is
