IMPORTANT
Product Safety Information
General - The following information is important in ensuring safety. It must be brought to the attention of personnel involved in the selection of the
equipment, those responsible for the design of the machinery in which it is to be incorporated and those involved in its installation, use and
maintenance.
The equipment will operate safely provided it is selected, installed, used and maintained properly. As with any power pumping equipment proper
precautions must be taken as indicated in the following paragraphs, to ensure safety.
Potential Hazards - these are not necessarily listed in any order of severity as the degree of danger varies in individual circumstances. It is
important therefore that the list is studied in its entirety:-
1) Fire/Explosion
(a) Oil mists and vapour maybe generated. It is therefore dangerous to use naked lights in the proximity of the pump openings, due to the risk
of fire or explosion.
(b) In the event of fire or serious overheating (over 300
o
C), certain materials (rubber, plastics, etc.) may decompose and produce fumes. Care
should be taken to avoid exposure to the fumes, and the remains of burned or overheated plastic/rubber materials should be handled with
rubber gloves.
2) Guards - Rotating shafts and couplings must be guarded to eliminate the possibility of physical contact or entanglement of clothing. It should be
of rigid construction and firmly secured.
3) Noise - The machinery may produce noise levels which are damaging to the hearing with prolonged exposure. Ear defenders should be
provided for personnel in these circumstances. Reference should be made to the Department of Employment Code of Practice for reducing
exposure of employed persons to noise.
4) Lifting - Where provided (on larger units) only the lifting points or eyebolts must be used for lifting operations (see maintenance manual or
general arrangement drawing for lifting point positions). Failure to use the lifting points provided may result in personal injury and/or damage to
the product or surrounding equipment. Keep clear of raised equipment.
5) Lubricants and Lubrication
(a) Prolonged contact with lubricants can be detrimental to the skin. The manufacturer's instruction must be followed when handling lubricants.
(b) The lubrication status of the equipment must be checked before commissioning. Read and carry out all instructions on the lubricant plate
and in the installation and maintenance literature. Heed all warning tags. Failure to do so could result in mechanical damage and in
extreme cases risk of injury to personnel.
6) Electrical Equipment - Observe hazard warnings on electrical equipment and isolate power before working on the unit or associated equipment,
in order to prevent the machinery being started.
7) Installation, Maintenance and Storage
(a) In the event that equipment is to be held in storage, for a period exceeding 6 months, prior to installation or commissioning, application
engineering must be consulted regarding special preservation requirements. Unless otherwise agreed, equipment must be stored in a
building protected from extremes of temperature and humidity to prevent deterioration.
The rotating components (gears and shafts) must be turned a few revolutions once a month (to prevent bearings brinelling).
(b) External pump components may be supplied with preservative materials applied, in the form of a "waxed" tape overwrap or wax film
preservative. Gloves should be worn when removing these materials. The former can be removed manually, the latter using a suitable
solvent. Preservatives applied to the internal parts of the pump do not require removal prior to operation.
(c) Installation must be performed in accordance with the manufacturer's instructions and be undertaken by suitably qualified personnel.
(d) Before working on the pump or associated equipment, ensure that the load has been removed from the system to eliminate the possibility of
any movement of the machinery and isolate power supply. Where necessary, provide mechanical means to ensure the machinery cannot
move or rotate. Ensure removal of such devices after work is complete.
(e) Ensure the proper maintenance of units in operation. Use only the correct tools and approved spare parts for repair and maintenance.
Consult the Maintenance Manual before dismantling or performing maintenance work.
8) Hot Surfaces and Lubricants
(a) During operation, pumps may become sufficiently hot to cause skin burns. Care must be taken to avoid accidental contact.
(b) After extended running the pump may reach temperatures sufficient to cause burns. Allow equipment to cool before servicing or performing
adjustments.
9) Selection and Design
(a) The driving and pipe work system must be correctly selected to ensure that the complete machinery installation will perform satisfactorily,
avoiding system critical speeds, cavitation, blockages, vibration, etc.
(c) The equipment must not be operated in an environment or at speeds, powers, flow rates or suction lifts beyond those for which it was
designed.
(d) As improvements in design are being made continually the contents of this catalogue are not to be regarded as binding in detail, and
drawings and capacities are subject to alterations without notice.
The above guidance is based on the current state of knowledge and our best assessment of the potential hazards in the operation of the pump.
Any further information or clarification required may be obtained by contacting our Application Engineers.

Shaft Alignment
Errors of alignment fall into categories of Angularity (fig1) and Eccentricity (fig 2) or a combination of both, errors of
angularity should be checked and corrected before the errors of eccentricity
Errors of Angularity
Errors of angularity can be checked using the following method:
Place a mark on both driving and driven hubs and measure the gap between them adjacent to the marks using a
block gauge and feelers at position 1 (see fig 3) then rotate both shafts together a quarter turn keeping the marks
aligned and take a another measurement at position 2, further measurements should be taken at positions 3 and 4
The difference between readings at position 1 and 3 can be used to calculate the error in the vertical plane and
difference between positions 2 and 4 should be used to calculate the error in the horizontal plane.
The errors of angularity across the coupling diameter can be calculated in both the vertical and horizontal planes,
The maximum error of angularity should be checked and adjusted to be within the coupling manufacturer’s
recommendations.
If the coupling faces are perfectly true then a stationary method can be used to check the errors of angularity:
Keeping both shafts stationary and take the horizontal and vertical measurements at the four positions (see fig 3)
Errors of Eccentricity
Errors of eccentricity require measurements to be taken in the radial direction, the simplest and most convenient
method* is to securely attach a dial indicator to one of the coupling hubs (as shown in fig 4) and rotate the hub
taking measurements at four points as shown, the difference between measurement points 1 and 3 represent the
vertical eccentricity and the difference between points 2 and 4 represent horizontal eccentricity.
The maximum error of eccentricity should be checked and adjusted to be within the coupling manufacturer’s
recommendations.
*More accurate alignment measuring processes such as laser alignment should be used when available
