SECTION 1 – GENERAL
INTRODUCTION
This publication is intended to assist those involved with
the installation, operation and maintenance of EBSRAY
Models ZB120 and Z580 Internal Gear pumps. The design,
materials and workmanship incorporated in the
manufacture of EBSRAY pumps make them capable of
reliable operation over a long working life. Correct
installation is essential. Service life is enhanced by
periodic inspection and careful maintenance.
1.1 CAUTION
INSTALLATION AND SERVICING OF THIS EQUIPMENT
SHOULD BE PERFORMED BY QUALIFIED COMPETENT
PERSONNEL IN ACCORDANCE WITH RELEVANT
STATUTORY REGULATIONS OR CODES, IN
CONJUNCTION WITH THESE INSTRUCTIONS.
When the equipment supplied utilises components other
than manufactured by EBSRAY e.g. couplings, speed
reducers, electric motors etc, reference should be made to
the original manufacturer’s data before installation or
servicing is commenced. Failure to observe these details
may void the warranty.
1.2 WARNING
The pump must be operated within the original selected
design parameters of speed, temperature, pressure and
viscosity. Should any change be contemplated, please
confer with EBSRAY in order to verify the suitability of such
a change.
1.3 TRANSPORTATION AND PACKING
Standard domestic packing is suitable for shipment in
covered transports. Ports must be sealed to exclude
ingress of solids. When received on site the pump should
be stored in a dry covered area.
If storage is required for other than a short period prior to
installation, special preservatives and protective wrappings
will be required.
1.4 INSPECTION ON RECEIPT – SHORTAGES
On receipt of equipment, check all items against the
dispatch documents and inspect for damage. Any damage
or shortage incurred during transit should be noted on the
packing note and on both your own and the carrier’s copy
of the consignment note and a claim should be made
immediately on the transport company.
Should a shortage be evident on receipt, notify EBSRAY
immediately giving full details and packing note number.
1.5 HANDLING
Care should be used in moving pumps. Do not drop pumps
and do not expose pumps to excessive heat or corrosive
materials. Baseplate mounted units should be lifted from
under the baseplate below both the pump and driver
ensuring compliance with the relevant lifting codes.
DETERMINATION OF MAINTENANCE REQUIREMENTS
EBSRAY Z Series Pumps are used for a wide range of applications and as such, maintenance requirements will vary between
applications. Under ideal/good operating conditions, providing pump is not run dry, internal inspection is generally not required
unless either performance drops off or unusual noises, vibrations or leaks occur. During inspection, check bearings and other
components for wear or damage.
Any reduction in performance (either flow, differential pressure or efficiency) will indicate either a system, Pumpset or pump
anomaly. Regular observation during operation will quickly identify symptoms such as leaking seals. Development of unusual
noises or vibration may indicate system/hydraulic problems, excessive wear, mechanical damage or foreign objects I the pump
