NOTES:

1. CPHM pumps with driving unit-11, 11A, 11B, 1 3 , 1 3 A are

supplied with oil lubrication bearings as a standard supply.

2. Pump models with suffix “N” are modified for improvement in rising

nature performance towards shut-off.

1.2 Description of ‘CPHM’ pumps:

KIR OSKAR CPHM pumps are of back pullout design which enables to remove

the rotating unit of the pump for inspection and repairs without disturbing the

pipe connections.

1.3 The complete range of CPHM pumps is covered by eight driving units thereby

reducing inventory and achieving interchangeability of parts.

1.4 Pumps when properly installed and given due care in operation and

maintenance should operate satisfactorily for a long period.

1.5 When the pump is received, sometime before the actual use, it should be

inspected and located in a dry place. The coupling should be rotated once in a

month to prevent pitting of bearing surfaces.

IOM/CPHM/DEC19/01 ISSUE DATE:14-12-2019

Page 4 | 48 REVISION NO.1

2. INSTALLATION:

2.1 For location, preparing foundation, installation, alignment, piping, general

maintenance, trouble, publication ‘GENERA INSTRUCTIONS FOR

INSTA ATION, OPERATION AND MAINTENANCE OF KIR OSKAR

CENTRIFUGA PUMPS’ which is also printed along with this booklet must be

followed carefully. If the pump is drawing liquid from the vessel under vacuum,

then vacuum equalizing connection piping must be made as per instructions

given in above publication. The external sealing connection to the pump, if

applicable, must be made after installing and before commissioning the pump.

2.2 Mounting and alignment:

A spacer type flexible coupling is recommended to connect pump shaft to the driver.

By using spacer type coupling, the complete rotating unit can be removed from the

volute without removing pump casing or motor and without disconnecting piping

connections. This also avoids any re-alignment of pump and motor after reassembly of

rotating unit. However, other types of coupling can be supplied against request.

Alignment:

A WAYS REMEMBER “F EXIB E COUP ING IS NOT A UNIVERSA JOINT”.

Correct alignment is essential for the smooth operation of the pump. There are two

types of mis-alignment between the pump shaft and the drive shaft which are –

i. Angular mis-alignment- Shaft with axis concentric but not parallel.

ii. Parallel mis-alignment- Shaft with axis parallel but not concentric. Mis-

alignment is checked by using straight edge as shown in Fig. 1 at 90

apart.

2.3

Before commissioning the pump set, please ensure:

2.3.1 The pipe connections are flushed and tightened properly.

2.3.2 Alignment is proper.

2.3.3 Auxiliary piping connection such as sealing / flushing, etc., are made.

2.3.4 ‘CPHM’ pumps are grease lubricated as standard supply. However, against specialty

oil lubrication can be given. Then the pump is provided with constant level oiler.

Please note that CPHM pumps in units- 11, 11A, 11B, 13, 13A are always with oil

lubrication.

2.3.4.1

Constant level oiler:

Fix the constant level oiler and fill the oil. Procedure for fitting the constant level oiler

and method of filling oil is given below.

Constant level oiler has plastic container and aluminum body as a standard supply.

Connection stem is ¼” BSP tapped and its capacity is 70ml approx. If the constant

level oiler is properly fitted and oil is filled as per instructions given, practically no

attention is required as far as lubrication of bearing is concerned other than to

replenish the visible reserve supply of the oil in the container (Refer Fig. 2, 3 and 4).

2.3.4.2 Method of fitting:

Screw constant level oiler stem into the tapped hole of the bearing housing reservoir.

Before fitting oiler, check the level of the tapped hole with the help of turn bar with

¼” BSP tapping at one end and a sprit level (Refer Fig. 2). If the level is incorrect and

oiler tilts downward, oil will not flow from oiler into the reservoir (Refer Fig. 3). Hence

it is necessary to check the level before fitting in the constant level oiler.

2.3.4.3

Method of filling the oil:

Tilt the container (Refer Fig. 4) and fill it with oil through stem of the oiler. Replace

the container and allow oil to flow into the reservoir. The oil in the container shall

flow into the bearing housing reservoir and shall become empty. Repeat above

procedure till the level in the reservoir is equal to the level of which the oiler is

adjusted. When the desired level is attained the oil in container shall remain steady at a

position. Visible level of the oil in the container indicates that bearing housing reservoir

is filled up to the mark.

IOM/CPHM/DEC19/01 ISSUE DATE:14-12-2019

Page 6 | 48 REVISION NO.1

CAUTION

1. In no case oil should be filled in directly into the bearing housing reservoir, through

breather cap.

2. Replenish the visible reserve supply of oil in the container as oil is used up.

3. Please ensure that “Air Groove” provided on aluminum body on which plastic

container rests, is not clogged with dust/fiber, oil film, etc. This groove allows

atmospheric air to enter inside the body to maintain oil level in bearing housing.

OPERATION:

3.1 Before startin the pump check the followin :

3.1.1 The pump rotates freely by hand.

3.1.2 Fill the grease/oil for bearings, if not done earlier. The bearings are packed with

grease/oil initially at the factory, however if the pump is stored for a longer time it is

necessary to refill the grease/oil in the bearings. Check the level of the oil in constant

level oiler is up to the mark.

3.1.3 The sealing liquid connections are properly tightened and adjusted.

3.1.4 The direction of rotation of the driver should correspond to the direction of rotation of

the pump.

3.1.5 The pump casing and suction pipe line is fully primed with liquid.

3.1.6 Valve on delivery side is closed.

3.1.7 The cock for pressure gauge connection is closed.

3.1.8 The gland bolts are properly tightened.

3.2 Startin the pump:

3.2.1 Start the pump. et the prime mover pick up its full speed.

3.2.2 Open the valve on delivery line gradually.

3.2.3 Open the cock for pressure gauge connection.

3.3

During running the pump check the following things and regulate, if necessary.

3.3.1 The pump is running smooth.

3.3.2 The bearings are not getting abnormally hot.

3.3.3 The gland is properly tightened to ensure sufficient leakage to dissipate heat generated.

Maximum permissible leakage is 60 to 80 drops per minute.

3.3.4 Head and capacity developed by the pump is as specified.

3.3.5 Power consumption is within limit.

3.3.6 Ensure that there is no mechanical friction in the pump.

3.3.7 Stop the pump immediately, if any defects are detected. Do not start the pump unless

defects are rectified. Report immediately to the supplier, if it is not possible to rectify

the defects.

3.4 Durin stoppin the pump:

3.4.1 Close the valve on delivery side.

3.4.2 Stop the motor.

3.4.3 If the pump is not required to be operated for a long time, drain the casing completely.

If the pump is required to be stored for a long time the bearing housing should be

dried internally with hot air and should be flushed with moisture free protective

such as light oil or kerosene.
