SECTION 1 –GENERAL
1.1 INTRODUCTION
This publication is intended to assist those involved
with the installation, operation and maintenance of
Ebsray RC Series Regenerative Turbine Pumps and
the pumping system.
Before starting any work,
this publication should be
completely read/reviewed by all persons involved
with the work. If any part of this publication is
unclear, obtain clarification before proceeding
with any work.
As LPG (Propane and
Butane) is regarded as a
flammable liquid, extreme caution must be taken
to ensure total compliance with all necessary
Statutory Standards, Directives, Codes and
Regulations is fully understood and exercised in
the installation, operation and maintenance of
Ebsray RC Series pumps.
These instructions are intended to assist correct
pump installation, operation and maintenance
requirements. They are additional to, and do not
supersede or override any applicable statutory,
legal or regulatory requirements.
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 and operation is essential. Service
life is enhanced by periodic inspection and careful
maintenance. Installation and servicing
of this equipment should
be performed by qualified
competent personnel in accordance with relevant
Standards, Directives, Codes, Regulations and
site restrictions, in conjunction with these
instructions.
When the equipment supplied utilises components
other than those manufactured by Ebsray e.g.
electrical equipment, switches, fittings, valves, 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.
The pumpset must be
operated within the
original selected design parameters of pumped
product (Use only LPG of internationally accepted
(ISO) quality and specification), flow, pressure,
temperature, voltage and current. Should any
change be contemplated, please confer with
Ebsray in order to verify the suitability of such a
change
1.2 TRANSPORTATION, PACKING & STORAGE
Standard domestic packing is suitable for shipment in
covered transports. Pump ports must be sealed to
exclude ingress of condensation, moisture or foreign
material. When received on site the Pump must be
stored in a dry covered area..
NOTE: If Pump is not installed and
commissioned immediately, special preservative
techniques will be required. (Refer to Ebsray).
e.g. If the Pump is installed, but not
commissioned, low pressure nitrogen can be
used to purge, seal and protect the Pump from the
effects of condensation and atmospheric
corrosion.
NEVER allow water or
any corrosive product to
enter the pump (e.g. for hydrostatic testing of
pipework). Severe internal damage may result and
will void the Warranty
1.3 RECEIVING INSPECTION
SHORTAGES and/or DAMAGE: 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

SECTION 2 –SYSTEM DESCRIPTION
2.1 EBSRAY RC20/RC25/RC40 LPG PUMPING
SYSTEM
The RC Series Pumps are designed generally for
installation aboveground when connected to
aboveground storage tanks. For Underground
installations refer to Ebsray.
2.2 BYPASS VALVE –EBSRAY MODEL RV18
(VRS OR CBS OPTIONS)
The RC Series Pumps must be installed in conjunction
with a bypass valve - connected back-to-tank. The
EBSRAY Model RV18 fitted with VRS or CBS option is
recommended. (Refer Ebsray Literature - P&ID for
details)
The Bypass Valve plays a pivotal role in the overall
LPG system. It controls the following functions:
1. Maintains pump system differential pressure as
required for optimum flow rates.
2. Controls Differential Pressure to maintain pump's
and/or motor's correct operation within intended
maximum operating parameters.
3. VRS option, when fitted, ensures rapid vapour
passage for faster pump priming before acting in
it’s intended liquid handling mode.
Fig 1
SECTION 3 –INSTALLATION
Installation and/or removal
of this equipment should
be performed by suitably qualified competent
personnel in accordance with relevant Directives,
Standards, Codes, Regulations, and site
restrictions - in conjunction with these
instructions.
Never loosen or remove
fittings, flanges, etc. while
under pressure (vapour pressure of LPG may be
very high), always isolate components or pipework
and depressurise prior to work.
3.1 PUMP & SYSTEM LOCATION/INSTALLATION
Refer Ebsray literature P&ID for system arrangement
and relative positions of important
components/equipment
3.1.1 Foundations
a) Pumpsets should be accurately and securely
installed. When mounted direct on a concrete
foundation, ensure that it has a solid footing and is
levelled on the pump mounting surfaces.
b) Ensure floor area and headroom allotted is
sufficient for inspection, maintenance and motor
cooling airflow. Allow for crane or hoist access if
required.
It is extremely important
that no piping stresses
be transferred to the pump.
3.1.2 Coupling
Ebsray can supply a compliant, non-sparking coupling
pre-bored to suit the Pump and most motors.
NOTE: Couplings must be of the non-sparking
design and be in compliance with the relevant
Directives, Standards, Codes & Regulations
3.1.3 Strainer
The pump inlet must always be protected by an
efficient strainer of adequate size to accommodate the
flow rate conditions without causing excessive inlet
resistance or cavitation.
3.1.4 Pump Inlet
a) The pump is designed for installation with an
adequately sized inlet pipe with continuous fall from
the LPG liquid withdrawal outlet of the tank.
b) Ensure this aboveground (exposed) inlet piping is
the shortest length possible –combined with the
minimum diameter (without causing cavitation) –thus
reducing the contained ‘vapour volume’ when priming.
c) Protection from direct sun will enhance pumping
performance by minimising vaporisation in pump and
inlet pipe. EBSRAY recommends that the pump and its
inlet pipework are painted white.
NOTE: Debris e.g. welding materials, pipe scale,
grinding swarf, shot blast material etc. left in the
pipework or tank will cause serious pump damage
and void the Warranty. Clean tank and pipework
TOTALLY prior to pumpset installation.
3.1.5 Pump Discharge
Discharge pipe size is generally dependent upon run
lengths at the specific site. Calculate as required to
ensure optimum conditions and to minimise pressure
drop.

3.1.6 Bypass Valve
Bypass Valve (Ebsray Model RV18-VRS or CBS) is
installed on the pump discharge side and returns back-
to-tank. It may be mounted directly on the 'spare'
discharge port or in the discharge pipe (before any
isolation valve). This Bypass Valve is primarily for
control of differential pressure. (NOTE: Variation in tank
vapour pressure has a direct effect upon discharge
pressure whilst constant differential pressure is
maintained).
If VRS option is used (Refer Appendix A - P&ID for
details), a critical function performed by this unique
Bypass Valve is its rapid vapour handling capability
during the pump start-up/priming cycle. (Also refer to
Ebsray RV18 Bypass Valve Brochure for details and
functionality.)
Ensure correct orientation i.e. flow is 'IN' from pump
discharge line and 'OUT' returns to tank.
NOTE: The Bypass Valve’s return-to-tank pipeline
MUST NOT have any restrictions which could
adversely affect, limit or block the unrestricted
vapour clearing function during pump priming.
An Excess Flow Valve or other 'normally open' tank
valve is recommended.
Flow of LPG during bypassing should return to Storage
Tank vapour space.
SECTION 4 –OPERATION
4.1 DESCRIPTION
1. Pump
The Ebsray RC Series pumps are designed for ultra
quiet operation pumping LPG of Internationally
accepted (ISO) quality and specification.
The Pump meets the requirements of Australian,
United States (UL listed for LP-Gas only), European
ATEX and other International Standards and Codes -
use in potentially explosive atmospheres.
2. Motor
Certified explosion protected IEC or NEMA motors fit
directly onto RC Series pumps. See Section 7 for
details.
Motor must be wired with a correctly sized IEC class
10A (or NEMA equivalent) thermal overload relay, and
set to no more than the FLA of the motor.
Ensure motor conforms to all necessary Directives,
Standards, Codes, Regulations and site requirements.
3. Coupling
Non-Sparking design (e.g. “Polygear” type) – is sized
to suit duty. Supplied by Ebsray or customer supplied.
4.2 LUBRICATION
The Ball Bearings for the RC Series pumps are
grease lubricated and 'sealed-for-life' design.
No 'in service' lubrication is required on Ebsray's RC
Series Pumps.
For motor, refer to specific motor manufacturer's
recommendations.
4.3 PRE-STARTUP CHECKLIST
Refer to pre-start inspection checklist (Appendix B)
Do not run Pumpset dry.
Do not start the Pump
against closed Discharge Valve. Severe internal
damage to the Pumpset will result, voiding
Warranty.
4.4 COMMISSIONING START-UP PROCEDURE
AND BYPASS ADJUSTMENT
Fill in the ‘Pump Run Log’ provided in Appendix C
1. Ensure all conditions described in Pre-Start-Up
Checklist have been met.
2. Check reading on discharge pressure gauge.
Record product vapour pressure in the commissioning
section of the Pump Run Log.
Differential pressure settings outside
the range of adjustment, requires a
different spring to be fitted.
3. To increase bypass pressure, rotate Adjusting
Screw in clockwise direction (i.e. screw in).
DO NOT exceed the lowest
service pressure rating of
any component in the system.
4. To decrease bypass pressure, rotate Adjusting
Screw anti-clockwise (i.e. screw out).
5. Ensure that there is an appropriate pressure gauge
fitted to Pumps’ main discharge viewable while
setting the Bypass Valve
Verify all site conditions
and statutory requirements
have been met and that the system is ready to
operate before attempting to set the Bypass Valve.
6. Rotate the Bypass Adjusting Screw anti-clockwise
until there is no resistance against the screw. This
is the Bypass Valve's minimum pressure setting.
7. Ensure that the system is set such that 100% of the
Pump’s flow is directed through the Bypass Valve
8. Briefly activate power (i.e. 'jog' motor) to verify
correct pump rotation. (Cast arrow on Cover).
9. Start the Pump and ensure that liquid is flowing
through Bypass Valve. This should be detectable
audibly (by listening) or by feeling the
valve/pipework by hand.
10. After start-up, pump should immediately begin to
build differential pressure. If pump does not
prime immediately, switch off to determine reason
and rectify before re-starting.

11. Screw in the Bypass Valve Adjusting Screw, not
exceeding two turns per minute until the desired
differential pressure is reached.
12. While retaining the Adjustment Screw, lock the
Adjusting Screw Lock Nut against Bypass Valve
Cover immediately after adjustment is made.
13. After the setting of the Bypass Valve is completed,
wire and seal Adjusting Screw, utilising holes
provided for passing wire through head of
Adjusting Screw and lug on Bypass Valve Cover.
Bypass Valves characteristically
exhibit two distinct pressures during
their operation:
a) The ‘setting’or ‘cracking’pressure which
occurs when the Bypass Valve first opens i.e.
initial bypassing begins against the preset
spring load, and;
b) ‘Maximum’pressure, which occurs when the
full flow of the bypassed product passes
through the Bypass Valve.
It is important to ensure both these above
characteristics are understood fully in order to
correctly apply the Bypass Valve.
If any aspect of the
Pumpset or pumping
system does not
function properly, immediately turn the pump 'off'
and rectify the problem before re-starting.
14 Record discharge pressure in the commissioning
section of the Pump Run Log.
15. Check that motor current is below FLA rating.
Record the motor current readings in the
commissioning section of the Pump Run Log.
NOTE: During this procedure, or at any time,
motor current must not exceed FLA rating of
motor.
16. Stop pump, restart and check for consistent results,
rectify if required.
17. Record discharge pressure and current readings in
the commissioning section of the Pump Run Log.
18. The Pumpset is now ready for normal operation.
19. The start-up procedure is now complete.
20. Inspect Pumpset/pumping system frequently during
the first few hours of operation then periodically
thereafter (see Section 4.5 for frequency).
Record the observations from these inspections in
the Pump Run Log.
4.5 PERIODIC INSPECTION
Periodic Inspection of the Pump, Pump System and
Ancillary Equipment is required to maintain safety,
conformity, operational functionality and reliability.
Ebsray recommends a maximum interval of three
months or 500 hours operation between routine
periodic maintenance inspections (More frequent
inspections may be necessary dependent upon
usage, site conditions, operation etc).
If any abnormal condition is discovered, cease
operation of pump immediately and take action to
rectify the problem. Record observations from these
inspections in Pump Run Log.
For safe operation, the following items should be
included in the routine periodic inspection:
a. Inspect the Pump for LPG leaks, vibration,
abnormal noises, signs of overheating,
discolouration, etc.
b. Inspect Coupling Assembly for signs of wear,
overheating, discolouration, etc.
c. Check Pump differential pressure
d. Check Motor Current.
e. Inspect motor for vibration, abnormal noises, signs
of overheating, discolouration, etc.
