WARNING
DO NOT OPERATE PUMP IF:
- The head is not installed correctly.
- Any guards are missing or incorrectly installed.
- The suction or discharge piping is not connected.
DO NOTplace ngers,etc. intothepumping chamber
or its connection ports or into any part of the gearbox if there is ANY possibility of the pump shafts being rotated. Severe injury will occur.
DO NOT exceed the pumps rated pressure, speed, and temperature, or change the system/duty parameters from those for which the pump was originally supplied,
withoutconrmingitssuitabilityforthenewduty.Running
the pump outside of its operation envelope can cause mechanical contact, excessive heat and can represent a serious risk to health and safety.
Installation and operation of the pump must always comply with health and safety regulations.
A device must be incorporated into the pump, system, or drive to prevent the pump exceeding its stated duty pressure. It must be suitable for both directions of pump rotation where applicable. Do not allow pump to operate with a closed/blocked discharge unless a pressure relief device is incorporated. If an integral relief valve is incorporated into the pump, do not allow re-circulation through the relief valve for extended periods (refer to section 3.8).
The mounting of the pump or pump unit should be solid and stable. Pump orientation must be considered in relation to drainage/cavity ventilation requirements. Once mounted, shaft drive elements must be checked for correct alignment. Rotate pump shaft by at least one full revolution to ensure smoothness of operation. Incorrect alignment will produce excessive loading and will create high temperatures and increased noise emissions. It may also be necessary to earth the pump head to avoid the build up of a potential charge difference that could cause a spark.
The installation must allow safe routine maintenance and inspection (to replenish lubricants, check for leakage, monitor pressures, etc) and provide adequate ventilation necessary to prevent overheating.
Fill all gearboxes with the recommended grades and quantities of lubricant (refer to section 3.4 and 8.3).
Beware ofover/underlling the gearbox as this could
cause the pump to overheat and mechanical damage to occur.
Before operating the pump, be sure that it and all parts of the system to which it is connected are clean and free from debris and that all valves in the suction and discharge pipelines are fully opened. Ensure that all piping connecting to the pump is fully supported and correctly aligned with its relevant connections. Mis­alignment and/or excess loads will cause severe pump damage. This could result in unexpected mechanical contact in the pump head and has the potential to be an ignition source.
Be sure that pump rotation is correct for the desired directionofow(refer to section 3.4).

DO NOT install the pump into a system where it will run dry (i.e. without a supply of pumped media) unless it is
equippedwithaushedshaftsealarrangementcomplete withafullyoperationalushingsystem.Mechanicalseals requirea thin uid lmtolubricate thesealfaces. Dry
running can cause excessive heat and seal failure.
Pressure gauges/sensors are recommended, next to the pump suction and discharge connections to monitor pressures.
Caution must be taken when lifting the pump. Suitable lifting devices should be used as appropriate. Lifting eyes installed on the pump must only be used to lift the pump, not pump with drive and/or base plate. If pump is base plate mounted, the base plate must be used for all lifting purposes. If slings are used for lifting, they must be safely and securely attached. For weights of bare shaft pumps, refer to section 8.6.
DO NOT attempt any maintenance or disassembly of the pump or pump unitwithoutrstensuringthat:
- The pump is fully isolated from the power source (electric, hydraulic, pneumatic).
- The pumping chamber, pneumatic relief valve and any shaft seal support system are depressurized and purged.
- Any temperature control devices (jackets, etc.) are fully isolated, that they are depressurized and purged, and components are allowed to reach a safe handling temperature.
DO NOT attempt to dismantle a pressure relief valve, which has not had the spring pressure relieved, is still connected to a pressurized gas/air supply or is mounted on a pump that is operating. Serious personal injury or death and/or pump damage may occur.
DO NOT loosen or undo the head, any connections to the pump, shaft seal housings, temperature control devices, or other components, until sure that such action will not allow the unsafe escape of any pressurized media.
Pumps and/or drives can produce sound power levels exceeding 85dB (A) under certain operating conditions. When necessary, personal protection against noise must be taken. Typical noise emission data can be found in sections 8.7 and 8.8.
Avoid any contact with hot parts of pumps and/or drives that may cause injury. Certain operating conditions, temperature control devices (jackets, heat-tracing, etc.), bad installation, or poor maintenance can all promote high temperatures on pumps and/or drives.
When cleaning, either manually or by an in-line cleaning method, the operator must ensure that a suitable procedure is used in accordance with the system requirements. During a in-line cleaning cycle, a pump differential pressure of between 2 and 3 bar (30 and 45 psi) is recommended to ensure suitable velocities are reached within the pump head. The exterior of the pump should be cleaned periodically.
Surface temperature of pump is also dependent on the temperature of pumped medium.

3.0 GENERAL
3.1 CLASSIC+ PUMPING PRINCIPAL
The pumping action of the rotary lobe pump principle is generated by the contra rotation of two pumping elements (rotors) within a chamber (casing) - see Figure 5. The rotors are located on shafts, which in turn are mounted within an external gearbox and supported by the bearings; the timing gears are also located on the shafts. The timing gears transfer the energy from the drive shaft to the driven shaft, synchronizing the rotors such that they rotate without contact with each other.
As the rotors pass the suction port, see Figure 5a, the cavity generated increases creating a pressure decrease, which
inducesthepumpedmediumtoowintothecasing.
The pumped medium is carried around the casing by the rotors; see Figure 5b and 5c, to the discharge side of the pump, Figure 5d. Here the cavity decreases and the pumped medium is discharged from the casing, Figure 5e.
For pump component terms, see Figure 4.
3.2 CLASSIC+ RANGE OPERATING PARAMETERS
The maximum pressure and speed operating parameters are given in Figure 6. In practice these may be limited due to the nature of the product to be pumped and/or design of the system in which the pump is to be installed. Consult Viking Pump or your Viking Pump distributor for assistance.
The operating temperature limit of the pump is determined by the rotor clearance. For the CP10, CP20, CP30 and CP40 series pumps there are three rotor clearance bands (class A, B and C), and two (class B and D) for the CP50 series pumps.
WARNING
The pump should not be subjected to sudden temperature changes to avoid the risk of damage from sudden expansion/ contraction of components. Care should be taken when selecting pumps for handling liquids containing abrasive particles as these may cause wear of pump head components. For advice or assistance contact Viking Pump or your Viking Pump distributor.
If the system or product characteristics are to be changed from the original application for which the pump was selected, Viking Pump or their authorized distributor should be consulted to ensure the pump is suitable for the new application.

- Incorporation of a torque-limiting device in the drive system.
It is recommended that all piping and associated equipment from the tank to the discharge point is thoroughly cleaned before installation of the pump to avoid the possibility of debris entering the pump and causing damage.
Pressure gauges should be installed adjacent to the pump suction and discharge connections such that system pressures can be monitored. These gauges will provide a clear indication of changes in operating conditions and where a relief valve is incorporated in the system, will be necessary for setting and checking the functioning of the valve.
It is imperative that the suction condition at the pump inlet meets the Net Positive Suction Head required (NPSHr) by the pump. Failure to observe this could cause cavitation, resulting in noisy
operation,reductioninowrateandmechanical
damage to the pump and associated equipment.
The Net Positive Suction Head available (NPSHa) from the system must always exceed the Net Positive Suction Head required (NPSHr) by the pump.
3.3.1 SYSTEM DESIGN AND INSTALLATION
When incorporating any pump into a system it is considered good practice to minimize piping runs and the number of pipe
ttings (tees, unions, bends etc.) and restrictions.  Particular
care should be taken in designing the suction line, which should be as short and straight as possible with a minimum of
pipettingstominimiserestrictingproductowto the pump.
The following should be considered at the design stage of any system.
Be sure ample room is provided around the pump

WARNING
Valves should be provided adjacent to the pump suction and discharge connections to allow the pump to be isolated from the system for routine inspection and maintenance.

toallowfor:
- Access to the pump and drive for routine inspection and maintenance, i.e. to remove pump head and rotors.
- Ventilation of the drive to prevent over heating.
The exterior of the pump unit may exceed 68°C (154°F); Appropriate measures must be taken to warn or protect operators.
The pump must not be used to support piping. All piping to and from the pump unit must be independently supported. Failure to observe this may distort the pump head components or assembly and cause serious consequential damage to the pump.
Rotary lobe pumps are of the positive displacement type and therefore an overload protection device
mustbeprovided.Thiscantaketheformof:
- An in-line pressure relief system, i.e. external to the pump.

- Before beginning operation, it is considered to momentarily start/stop the pump to check the direction of rotation and ensure that the pump is free of obstructions. Once this has been carried out, begin operation keeping a visual check on suction and discharge pressure gauges and monitor the pump temperature and absorbed power where possible.
- Check that all piping and associated equipment are clean and free from debris and that all pipe connections are secure and leak free.
- For pumps tted with ushed product seals
check all auxiliary services are in place
and connected and provide sufcient ow and pressure for ushing purposes, refer to
section 7.0.
- Ensure lubrication is provided for both pump and drive. The Classic+ is shipped without oil
as standard and should be lled to the level
of the oil sight glass - refer to section 8.3 for pump oil capacities and grades.
- If an external relief valve is incorporated in the system, check that it is set correctly. For start up purposes, it is considered good practice to set the relief valve lower than the system design pressure. On completion of start up, the relief valve should be reset to the required setting for the application. The required setting should never exceed the lower of either the pumps maximum pressure rating or the system design pressure. For setting integral relief valves refer to sections 3.8.1 and 3.8.2.
- Be sure both suction and discharge valves are fully opened and that pipe work is free from all obstructions. The Classic+ is a positive displacement type pump and should therefore never be operated against a closed valve as this would result in pressure overload, resulting in damage to the pump and possibly the system.
- Make sure that the drive shaft rotation is correct
forthedirectionofowrequired.SeeFigure8.
- Be sure product is available in the suction vessel before starting the pump. This is very
important for pumps tted with un-ushed

3.8 INTEGRAL PRESSURE RELIEF VALVES
See Figures 11, 12, 13 and 14.
The Classic+ models CP10, CP20, CP30 and CP40 can be supplied with integral pressure relief valves. For the CP10, CP20 and CP30 both spring and air loaded versions are available. The function of the valves can be further enhanced with the option of manual or airlift override, offering particular
benetswhere CIPorSIPproceduresareemployed.Valves incorporating this option can be opened to regulate the ow
of the cleaning media through the pump chamber, thereby avoiding the need for manual cleaning or external bypass.
Where the pump is mounted onto a portable base plate, complete with motor and drive to be used as a mobile set, an integral pressure relief valve should be installed.
TheClassic+integralpressurereliefvalvesavailableinclude:
Spring Loaded - see Figure 11.
- Valve can be set to the required pressure relief setting.
Spring Loaded with Manual Lift - see Figure 12.
- Valve can be set to the required pressure relief setting.
Manual lift override can be used to open valve without disturbing pressure relief setting.
Spring Loaded with Air Lift - see Figure 13.
- Valve can be set to the required pressure relief setting. Air
override, which operates on an air supply of up to 7 Bar (102 psi) depending on pressure relief setting, can be used to open valve without disturbing pressure relief setting.
Air Loaded with Air Lift - see Figure 14.
- Valve, which operates on an air supply of up to 7 Bar
psi) regulated for required setting, can be set to the required pressure relief setting. Airlift override, which operates on an air supply of up to 7 Bar (102 psi) depending on pressure relief setting, can be used to open valve without disturbing pressure relief setting.
Air actuated relief valves can be operated remotely and inter­faced with other elements of the system or process control.
WARNING
Ifthepumponwhichthevalveisttedistobeinstalledwithin
either a pressurised system or one incorporating a vessel under vacuum then the application of the valve should be referred to Viking Pump.
Integral pressure relief valves are normally used to protect the pump from the effects of increases in system pressure caused, for example, by a restricted or closed discharge line. In response to a pressure increase, the valve opens and internally circulates the pumped media within the pump chamber. When the valve opens, because the volume of liquid circulating is relatively small, the temperature of the liquid in the pump chamber may rise if the pump continues to operate for an extended period. In severe cases, this may result in temperatures in excess of the pumps operating limits, or vaporisation of the liquid, both of which should be avoided. For these reasons when the valve is activated the cause of the system pressure increase should be eliminated as continuous operation of the pump with the valve open is not recommended and may cause severe damage to the pump.

The selection, setting and application of integral relief valves is
inuencedbytheviscosityandnatureofthepumpedmedia,the
pumps operating speed and the required pressure relief setting and mode of operation. For these reasons and to cover the diverse range of products, the conditions under which they are pumped and application demands, it is not practical to factory­set integral relief. Valves and the setting of the valves should be carried out on site, under the proposed duty conditions for which the pump and valve were selected.
For setting and operating Classic+ integral relief valves refer to sections 3.8.1 and 3.8.2. Before beginning the relief valve setting procedure the pump should be installed, refer to section
3.3.1, paragraph (vi), with a pressure gauge in the discharge line adjacent to the pump discharge port.

Note: Care should be taken not to exceed the lower of either the pump’s maximum pressure rating or the system design pressure.
- To use the air lift system, the regulated air supply must be routed through a change-over valve in order to transfer air from the relief valve load air chamber, connection ‘A’, to the lift air chamber, connection ‘B’, while depressurizing the load chamber and vice versa. The change­over valve will actuate the air lift which will lift when the air supply is diverted to connection ‘B’, and will close, restoring normal relief valve operation, when the air supply is diverted back to connection ‘A’.
DANGER !
Under no circumstances should any attempt be made to dismantle a pressure relief valve which has not had the spring pressure relieved, is still connected to a pressurized air supply, or is mounted on a pump that is operating. Serious personal injury or pump damage may occur.

components should be replaced.
Thepositionofallpartsshouldbeidentiedastheyareremoved
to ensure they are reinstalled in the same position.
Lipseals and O-rings are incorporated within the gearbox assembly to contain the lubricant for the bearings and timing gears. Regular inspection and correct maintenance of these items will ensure that the lubrication is sustained and the pump maximum working life is achieved. To ensure this, it is extremely important that care is taken when removing and replacing new O-rings and lipseals. When removing and replacing lipseals ensure that the location bore for the outside diameter and the seat for the back of the lipseal is not damaged as this may create a leak path for the lubricant.
When removing lipseals or O-rings care should be taken to avoid cutting or tearing the sealing faces as they pass over keyways, splines, threads or other potentially sharp or abrasive edges. All lipseals and O-rings should be carefully examined and if damaged in any way, be replaced.
All O-rings and sealing lips of lipseals should be lightly lubricated with an appropriate lubricant (suitable for application) before installing.
When installing lipseals do not allow the rear face to come into contact with bearings or other rotating parts.
Prior to beginning assembly, ensure all parts are clean and free from burrs or damage. Where a vice is to be used then this should be installed with protective jaws to avoid damage to components. Do not hammer or apply undue force to install or position components.

Under no circumstances should bearing cones or cups be hammered into position.
recommended Shutdown Procedure should be followed, refer to section 3.5.
While disassembling or assembling the pump it is essential to ensure that the pump and/or components are secured to provide adequate stability.
Large pump components or sub-assemblies should be installed using suitable devices. Use threaded holes for the attachment of lifting eyes where appropriate.
All fasteners are required to be tightened to the required torque setting during assembly, refer to section 8.2.
The preferred method of installing bearing cones is that they are heated to approximately 125°C (250°F) prior to installation. During this operation protective gloves should be used. Once bearing cones are installed in the correct position they should be allowed to cool before proceeding with assembly. As an alternative, bearing cones may be pressed into position providing the proper equipment is utilized and the necessary procedures are used to prevent component damage.

5.0 CLASSIC+ MECHANICAL SEAL REMOVAL & REPLACEMENT
5.1 GENERAL PROCEDURES FOR INSTALLING MECHANICAL SEALS
“Quick summary” of mechanical seal installation
- Mechanical seals are precision-engineered assemblies
incorporating finely lapped seal faces and seats. They must be handled with care and will not give optimum performance unless installed carefully and according to instructions.
- When mechanical seals are to be reused, ensure seal
components are kept in their appropriate sets. Do not mix old and new seal faces on the same seal.
- Remove any sharp corners and burrs that may damage any
elastomers such as O-rings or lipseals.
- Be sure that all seal component fitting bores and housings
are thoroughly cleaned before installation.
- The seal faces and seats must be handled with care and
cleaned thoroughly before installation.
- Be sure that seal faces are undamaged and the O-rings are
not cut, swollen or cracked.
- All O-rings should be lightly lubricated with a suitable
lubricant (silicon grease, soap etc.) before installation but ensure there is no excessive amount of lubricant especially around the seal face area.
- Ensure when installing seals with brittle faces and seats
such as silicon carbide that extra care is taken.
- Do not use any excessive force to install a mechanical
seal. If it is difficult to position and assemble the seal then something is wrong.
- If you drop or damage a seal, do not install it before an
inspection has been carried out.
WARNING
- Do not run a mechanical seal dry.
- Remove head (1.01), rotor retainers (2.02), O-rings (2.04) and casing (3.01), refer to section 4.1.2.1 (CP10, CP20 and CP30) or section 4.2.2.1 (CP40).
- Loosen but do not remove screws in rotary cartridge as (7.05) which secure rotary seal cartridges to shafts (5.01 and
5.02).
- Remove rotary seal cartridges (7.05) with O-ring (7.02) from shafts (5.01 and 5.02).
- Remove stationary seal seats (7.04) and O-rings (7.01) casing (3.01).

WARNING
!
The media used for quenching or flushing a seal area must be fully compatible with the pumped media, and the relevant materials of construction of the pump.
Special consideration must be given to the temperature limitations of the media to ensure that no hazards are created, e.g. risk of fire or explosion.
7.1 SINGLE MECHANICAL SEAL (FOR LOW-PRESSURE QUENCH OR FLUSH)
See Figure 17 (CP10), Figure 27 (CP20, CP30, CP40) and Figure 50 (CP50).
Refer to section 4.3.3.
This seal arrangement requires a supply of media to the
outboard side of the mechanical seal to quench or ush the sealarea.Thenatureofthe pumped media and the specic dutyconditionswill determinewhethera quenchoraush is
required.
A quench provides a static head. The quench media vessel should be mounted a minimum of 0.5m (1.5 Feet) above the pump, preferably directly above the seal area. The interconnecting pipe work should be as straight as possible, avoiding horizontal runs, and with the minimum number of bends and restrictions.
Forasuitableush,themediamustbesuppliedataowrate
of 4.5 Liters per minute per shaft seal.
WARNING
Note: The limiting flush or quench pressure in any application is 0.7 Bar (10 psig).
7.2 DOUBLE MECHANICAL SEAL (FOR HIGH PRESSURE FLUSH)
See Figure 18 (CP10) and Figure 28 (CP20, CP30, CP40) and Figure 51 (CP50)
Refer to section 4.3.4.
This seal arrangement requires a supply of media to be circulated between the inboard and outboard mechanical seals.
Theushmediamustbesuppliedataowrateof4.5Litersper
minute per shaft seal assembly.
Theushpressuremustbeaminimumof1Bar(15psi)greater
than the maximum discharge pressure created by, or the maximum suction pressure applied to, the pump, whichever is the greater.
WARNING
Note: The liquid supply connections to ushed seals are made using the threaded ports on the sides of the seal housings (two per seal, except CP10 & CP20 models, which have common seal housings encompassing both shaft seals). For models CP30 to CP50 inclusive, one
port on each housing should be used for ush ‘in’ and the other for ush ‘out’. The pipe work should be arranged to provide an independent ush to each seal.
Note: The limiting flush pressure in any application is 13 Bar (188 psig).
