Service intervals
This workshop manual can be used for both regular inspection and complete overhaul on the pump. For assis-
tance contact Sulzer workshop or by Sulzer authorized workshop.
- For regular inspection on the pump such as electrical check, oil/motor check and check of hydraulic parts,
proceed and follow section 1 to 6 in this manual.
- For complete overhaul on the pump proceed and follow section 1 to 9 in this manual.
- For electrical information and wiring diagrams see section 10.
Submersible drainage pumps J 205 - J 604 are built for long periods of trouble free operation. The pumps can
“run on snore” without any risk for the mechanical seals. They get sufficient cooling from the pumped media
and sufficient lubrication and cooling from the oil in the housing between the seals. All the ball bearings are
sealed and pre-filled with high performance bearing grease for life time duty.
Regular inspection and preventive maintenance will ensure more reliable operation. The pump should be
inspected every six months and should have a complete overhaul once a year. If the operating conditions of
the pump is severe it may be required more frequently. A reason for inspection could be if a drop in capacity is
being noticed.
1.2 Repair ki
ts
The repair kits includes preselected spare parts which secures a fast and efficient maintenance and avoids
unnecessary downtime for the pump. For contents of repair kits see spare part lists.

(*=M14 nuts under diffuser and bottom plate use 45 Nm.)
Cable gland: A specific torque value cannot be given for the cable gland. Tighten it until the rubber offers re
-
sistance, and thereafter, one more full rotation. Sulzer recommends to always use anti seize UNLOCK 2000 or
equal lubrication on gland threads.
