Measuring the power supply voltage
Power supply voltage tolerance
a. continuous running: max±5% of the rated voltage.
b. intermittent running: max±10% of the rated voltage .
Inspecting the impeller
If the performance level has decreased considerably, the impeller may
be worn.
Semi-annually
Inspection of lifting chain or rope
Inspecting and changing oil.
Yearly
Changing the oil and replacing the mechanical seal in the chamber.
Every 12 months or after 6,000 hours of use, whichever comes first.
NOTE:
Contact the dealer from whom you purchased the equipment or the
Solidpump sales office in your area to inspect and replace the
mechanical seal.
Once every
2 to 5 years
Overhaul
The pump must be overhauled even if the pump appears normal during
operation. The pump may need to be overhauled earlier if it is used
continuously or repeatedly.
NOTE:
Contact the dealer from whom you purchased the equipment or the
Solidpump sales office in your area to overhaul the pump.
(2)Storage
If the pump will not be operated for a long period of time, pull the pump up, allow it to dry, and store it indoors.
NOTE:
Be sure to perform a trial operation before reinstalling the pump. If the pump
remains immersed in water, operate the pump on a regular basis (i.e. once a
week) to prevent the impeller from seizing due to rust.
(3) Maintenance
Inspecting oil and Changing oil
Inspecting oil
Designated oil: Turbine oil VG32.
Oil volume : Specified volume.
Remove the oil plug and take out a small amount
of oil. The oil can be extracted easily by tilting the
pump so that the oil plug faces downward. If the oil
appears discolored or intermixed with water, a
likely cause is a defective shaft sealing device
(i.e. mechanical seal), which requires that the
pump be disassembled and repaired.
Changing oil
Remove the oil plug and drain the oil completely.
Pour a specified volume of oil into the oil filler inlet.
NOTE:
The drained oil must be disposed of by waste
disposal contractors in compliance with the
laws of the located where the pump is being used.
The gasket and the O-ring for the oil filler plug
must be replaced with a new part at each oil
inspection and change.

The oil volume for the models which is not included in the tables :about 80% of
the total oil cylinder capacity (theoretically, the oil level should cover the mating ring)
The parts listed below are dispensable items. As a rule of
thumb, Use the replacement period as a guide to replacing
these parts.

(4) Disassembly and reassembly procedure
DANGER:
Disconnect and lock out electrical power before installing or servicing
the unit.
WARNING:
A worn impeller and/or pump housing can have very sharp edges.
Wear protective gloves.
CAUTION:
Make sure to perform a trial operation when starting the pump after a
reassembly. If the pump was assembled improperly, it may lead to
abnormal operation, electrical shock, or water damage.
