8. MAINTENANCE
To perform the maintenance of the J Line pump, no special (custom made) tools are needed.
Before initiating maintenance procedures disconnect all power sources to the
equipment and discharge any parts which may retain an electric charge. Use
proper locks to avoid accidental start-up of the pump system. Failure to comply
may result in severe personal injury.
When performing the maintenance of the pump, use the safety equipment
appropriate for the pumped fluid, materials, and location of the equipment, such
as gloves, safety glasses, harnesses and other equipment regarded as mandatory
by the plant’s safety instructions.
IMPORTANT: For any component/accessory that has not been manufactured by
Ruhrpumpen and is part of the pump’s equipment, a complete reading of said
component/accessory manufacturer’s manual must be carried out for further
information on proper maintenance procedures and relevant safety warnings.
Correct and orderly installation/assembly is necessary for trouble-free operation
of the unit. Ruhrpumpen does not assume any liability for damage resulting from
inadequate installation/assembly. The chosen location for installation must offer
enough space for maintenance activities. Ruhrpumpen recommends consulting
also API Recommended Practice 686 to ensure proper installation in your facility.
