during transportation.
• If any damage has occurred during transportation, notify SERVICE DEPARTMENT, STANDART
POMPA and SHIPPING COMPANY about it immediately.
• Check whether all materials in the shipping list have been delivered. If there is any missing article,
advise SERVICE DEPARTMENT, STANDART POMPA.
• Remove the liquid inside the pump, for preventing corrosion due to transportation.
3.2- Handling
3.2.1- General warnings
• Follow the rules at work to prevent occurrence of any accidents.
• Wear gloves, steel-tooled shoes and helmet during handling.
• You may use forklift, crane or hoisting ropes to lower wooden crates, packages, pallets
or boxes depending on volume, weight and construction of them.
3.2.2- Lifting operation
- Total weight and centre of gravity, - The largest outer dimensions, and
- Location of the lifting points.
• The load lifting capacity should comply with the weight of the pump or pump group.
• The pump or pump group should always be lifted and handled horizontally.
• Never stand under or near the load being lifted.
• Do not keep the load lifted longer than necessary.
• Accelerating and braking operations during the hoisting should not be performed in such a way that
may be dangerous for the working personnel.
The pump or pump group should be hoisted as shown in the Figure 1a or Figure 1b in order to avoid
from any deformation. (When the group is hoisted as a whole, never use the suspension hook of the
electric motor.
ATTENTION
• Determine the following points prior to lifting and handling the pump or pump and
motor group on the joint frame.
Fig 1b. Pump and motorFig 1a. Bare shaft pump

05
3.3- Storage
• If the pump will not be installed in place immediately, it should be stored at a clean and dry place
free of any frost hazard without excessive change in the ambient temperature.
• If the pump bearings are of grease-applied ones, extra grease should be applied to the bearings to
prevent moisture ingress around the shaft.
• Necessary precautions should be taken to protect the pump against humidity, dust, dirt and foreign
materials.
• The pump should be rotated manually by some turns occasionally (e.g. once in a week) to prevent
pitting on the bearing surfaces and sticking of the pump.
4- INSTALLATION ON SITE
Installation of the pump on site and levelling and adjustments of it should be performed only by
qualified personnel. Improper installation or pump base (foundation) may cause failure. Such situations
are excluded from warranty.
Installation on site should be performed as per NFPA 20 standard.
4.1- Bare Shaft Pump
• If the pump is purchased as bare shaft pump, then first a proper baseplate should be constructed
to connect the pump and motor group. The baseplate should be designed and manufactured in such
a way that it will have resistance to prevent vibration and deformation.
• If the pump is supplied without motor, proper motor and coupling should be selected before the
group is installed.
• Following points should be taken into consideration when selecting motor:
- Maximum power drawn by the pump along the entire operating range,
- Running speed of the pump,
- Applicable power supply (frequence, voltage, etc.),
- Motor type (IEC, NEMA),
- Motor connection form (pedestal, flanged, horizontal, vertical, etc.), and
• Rated motor power, rpm and type of drive should be taken into consideration when selecting coupling.
4.2- Preparation for Installation
Prior to installation of the pump in place:
• Suction and delivery flanges should be cleaned thoroughly.
• Protective film on the pump shaft should be removed.
• If the pump has been stored temporarily, the liquid oil in the bearings should be drained completely
(in case of pumps manufactured with liquid oil) and the bearings should be cleaned by a proper
cleaning agent and then oiled again. This operation is not required for the pumps lubricated by grease
and for the pumps using enclosed type of ball bearing.
ATTENTION
• The pump should be installed at a well-ventilated place free of freezing and explosion risk.
•There should be sucient space around the pump being installed to allow easy access for
maintenance of the pump as well as sucient space above the pump to hoist it when required.
• Suction pipe of the pump should be short as far as possible.
4.3- Installation Site
ATTENTION

06
4.3.1- General characteristics of the pump foundation (baseplate)
You should work carefully for preparation of the pump base and installation of the pump
group in place. Improper and careless installation may cause excessive vibration and premature
wear of the pump equipment as well as pump failure.
ATTENTION

• Sizes of the foundation concrete should be determined on basis of minimum 10% excess of the
frame dimensions.
• Pump foundation should be independent of other foundation and platforms.
• Pump foundation should be capable to absorb vibrations and bear the loads to apply on the pump
unit during operation.
• Place and dimension of the anchor bolts should be determined according to the hole dimensions
of the pump unit.
• Washer should be used to prevent tension and distortion when tightening the foundation bolts.
• In order that the foundation bolts should align with the connection holes of the frame exactly and
to allow for minor adjustments, the bolts are inserted into the bushings. The bushings should be
place in such a way that they will not exceed top surface of the foundation concrete.
4.3.2- Placement of the Pump Group
•Preparation and pour of the foundation concrete mass.
-The concrete mass is formed according to its dimensions.
-The locations of the anchor bolts are measured and marked carefully and Styrofoam is
cut tothe dimension, placed and fixed.
-The concrete is poured
Volume ratio: Cement 1: sand 2: gravel 4
Concrete hardens within 7 days (hardening may be shortened by use of special cement).
-Upon hardening of the concrete, the Styrofoam is burned and removed. Locations of anchor
bolts appear in the concrete.
-Top surface of the concrete and holes of the anchor bolts are cleaned.
•Placement of the frame on the foundation concrete mass. (first adjustment)
-Anchor bolts are mounted on the frame.
-The frame is placed on the flattening chocks and the anchor bolts remain suspended
in the holes. Make sure that the anchor bolts remain vertical.
-Levelness of the frame is controlled in both directions from the pump and engine
placement location by use of precise spirit level 0,25 ÷ 0,40 mm/m is acceptable.
- Anchor holes are fileed with concrete. Anchor bolts are thus fixed.

07
• Never use the pump as a point of support or bearer for the piping system.
ATTENTION
Volume ratio: Cement 1 : sand 1.5: gravel 3
Concrete hardens within 7 days (hardening time may be shortened by use of special cement).
•Fixing of the frame on the foundation concrete mass exactly by adjustment.
-The area about 30mm between the foundation concrete mass and frame is formed and
concrete is poured through the holes in the frame.
Volume ratio: Cement 1: sand 2
Concrete hardens within 2 days.
-Frame remains adjusted and fixed on the foundation concrete.
4.4- Installation of the Piping System
4.4.1- General Warning
• The piping system should be supported at points near to the pump. For this purpose, after completion
of the installation of the piping system, loosen the bolts of the suction and delivery flanges and
control whether the piping system applies any tension on the pump. The maximum allowable forces
and moments on the flanges are given in Table 1.
• Rated diameter of the suction and delivery flanges of the pump are not indicator of the correct
sizes of the suction and delivery pipes at all. The rated diameter of the pipes and accessories used
should be equal to or larger than the inlet diameters of the pump at least. Never use pipes and
accessories having smaller diameter than the inlet diameters of the pump. Especıally components
such as, strainer, dirt-retaining filter and check valves with larger free passage area should be preferred.
• Pipe connections should be made with the flanges. Flange bolts should be made of proper material
and in proper size. The flange bolts should be inserted between the flange bolts and centred in such
way that it would not impair flow section.
• In case of excessive vibrations, expansion parts should be used in order that any extra forces that
may arise from thermal expansion are not transferred to the pump.
• Materials such as welding burrs, metal particles, sand and oakum arising from production of fhe
piping system may remain in the pump and give damage to the pump. The suction and delivery
flanges should be sealed blind washers in order to prevent such materials from entering into the
pump during the assembly operations. After assembly, all pipe parts should be removed, cleaned,
painted and reassembled. If dirt-retainer is used on the suction side of the pump, the dirt-retainer
should be cleaned after working for several days.

4.4.2- Suction pipe
• The suction pipe should be definitely watertight and should not be arranged in a way to cause
formation of air pockets. Figure 3
• In order to keep the loss from friction, sharp elbows should not be used; and abrupt change of
direction and section should be avoided and suction pipe should be made short as far as possible. If
it is required to make change of section on a horizontal suction pipe, an eccentric conical spacer with
its flat side on the top should be used.
4.4.3- Delivery pipe
•A flow control valve should be connected on the delivery pipe, near the pump as far as possible in
order to adjust the flow rate and delivery head. Figure 4
• An insulation valve should be
used to keep the axis on the suction pipe horizontally. This valve should always be open
when the pump operates and it should never be used as flow rate adjusting valve
(Caution: Throttle of the valve may cause the pump to operate with cavitation).
ATTENTION

After installation of piping system, coupling allignment should be checked and if necessary
it should be adjusted again.
4.4.4- Auxiliary pipe connections and accessories
•Depending on the application auxiliary pipe connections (for cooling, sealing and flushing of seal,
drainage etc. necessary for the pumping system) and/or accessories to check operating conditions
(pressure gauges, temperature gauges etc.) may be made up and lail.
•Pressure and vacuum gauges must be properly anchored and connected at the measuring points
located on the pump flanges by means of or on the pipes close to the flanges. For safety purposes
isolating and vent valves should be fitted before the gauges.
•Cooling, sealing and flushing of seal piping must be connected only to the designated connections
located on the pump.
ATTENTION

10
4.5- Coupling Adjustment
After installation of the baseplate and system
connections, the coupling adjustment should be controlled
finally. The reason that proper adjustment of the entire
system is responsibility of the purchaser.
“Coupling Adjustment” is to ensure that the
rotation axes of the motor and pump should be on the same
plane. SDS type pumps are ordered with motor and
baseplate, they are delivered with the coupling adjustments
made at the factory. However, this adjustment may be easily
impaired during transportation, handling, installation on
site and installation of the system. For this reason, the
coupling adjustment should be performed again after
installation of the group on site, disregarding the adjustment
made at the factory.
• The most important factor for problem-free operation of
the pump group is correct coupling adjustment. The basic
reason of a number of problems such as vibration, noise,
bearing heating and overload is a coupling unadjusted or
improperly adjusted. For this reason, coupling adjustment
should be performed very well and controlled frequently.
• Elastic coupling should not be regarded as a component to
correct an improper adjustment. Elastic coupling does not
correct a poor axial adjustment between the pump and motor
and does not remove excessively poor adjustments.
• A metal part (steel ruler or gauge, etc.) and a precise caliper
are required to perform coupling adjustment (special
equipment should be used for very fine and precise
adjustment). Axial run-out of the coupling (see Figure 5)
should not exceed 0.1 mm.
• There may be two types of adjusting mistakes on the
coupling:
a) Angular mistake
b) Parallel displacement mistake
• In order to control the angular mistake, the distance
between two parts of the coupling should be measured
mutually on horizontal and vertical planes. The clearances
measures at these four points should be equal (Figure 6a,6b).
ATTENTION

Fig 6d. Parallel sliding error in vertical
plane and adjustment.

• In order to control the parallelism mistake, a gauge with straight edge is pressed on a part of the
coupling in parallel to the axis and the position of the gauge related to other part is observed. The
gauge should contact with both two parts simultaneously and along its entire edge. This process
should be performed at two opposite places on the horizontal and vertical plane (Figure 6c, 6d).
• Adjustment mistakes may be on the horizontal and/or vertical plane. Mistakes on the vertical plane
may be made by putting thin metal sheets under the pump or motor mounts and the mistakes on
the horizontal plane by benefiting from the gaps in the connection holes or sliding the engine on the
horizontal plane. Manner and order of the coupling adjustment is shown inthe Figures 6a, 6b, 6c
and 6d, respectively.
4.6- Electrical Connections
• Electirical connection should be done by a qualified electrician. Current national regulation and
motor manufacturer’s instructions must be observed.
• Take all safety precautions listed in “Safety instructions”. Disconnect all power supplies prior to
doing any work.
• The supply cable must be laid in such a way that it never touches the pipework, pump and motor
casing.
• Check voltage, phase and frequency on motor nameplate with the mains.
• The electric motor must be protected against overloading by means of circuit breakers and/or fuses.
Circuit breakers and fuses must be selected in accordance with full load amperage of the motor
appearing on the motor rating plate.
• Prior to connection the electrical wiring rotate the pump shaft by hand to make sure rotor rotates
easily.
• Connect the electrical wiring in accordance with local electrical codes and make sure to ground the
motor.
• The connection diagram can be found in the terminal box of the motor or in the instruction manual.
• The mains connection on the terminal box depends on the nominal power of the motor, the power
supply and the type of connection. The necessary coneccton of the bridges in the terminal box is
shown in the following (Table 2 ve Figure 7a, 7b, 7c).

In the case of three-phase induction motors with Y - ∆connection it must be ensurred that
the change-over points between star and delta follow on from one another very quickly.
Longer change-over times may result in pump damage (Table 3).
4.7- Final Controls
• After all operations given above are completed, the coupling adjustment should be controlled once
more in accordance with the section 4.5. And if it is incorrect, it should be corrected.
• The pump rotor should be rotated several times manually to make sure it rotates easily.
• All security guards should be put in place.
• And the pump group should be operated and you should allow until the operating and heating
conditions are reached.
• At the end of this term, the pump is stopped and thin metal sheets are put under the motor mounts
only to perform coupling adjustment for the last time.
• Final coupling adjustment is especially recommended to be performed at the operating temperature.
• The pump should never be operated before the safety guards are put in place. This is a
security and safety rule at workplace which should be definitely observed.
ATTENTION

5- START UP / SHUT DOWN
5.1- Preparation
5.1.1- Lubrication control
• The bearings of SDS type pump are always lifetime grease lubricated. Lifetime grease lubricated
bearings are maintenance-free.
5.1.2- Venting and priming
• Make sure that the pump and suction pipes are completely filled up with water. There is no problem
for the pumps which have positive suction head. If there is a valve on suction line, it must be opened
and air taps are loosened to enable the water replaces air in the pump, until it is completely full with
water.
Make sure the pump never runs dry.
5.1.3- Checking the direction of rotation
• SDS type pumps rotate in clockwise when it is looked from coupling to the pump. This direction is
already indicated on the pump by an arrow. Check this by switching the pump on, then o again
immediately. Fit the coupling guard back in place if you took it out.
5.2- Start Up The Pump
• Check if the shut o valve in the suction line is open.
• Switch on the circuit breaker and run the motor.
• Wait until the motor reaches the full speed (on star-delta running motors wait until it switches on
delta).
• Pump doesn’t deliver any water,
• Pump doesn’t deliver enough water,
• Flow is going down,
• Discharge pressure is not enough,
• Driver overloaded,
• Vibration on pump,
• High noise level,
• Bearing overheating.
ATTENTION
The pump should be shut down at once and the trouble should be corrected if the pump
is running at its rated speed and found any of the following faults:
ATTENTION

5.3- Checks to be Made While The Pump is Running
• The bearing temperature may exceed the ambient temperature by up to 50 ºC. But must never rise
above 80 ºC.
• The valves in the auxiliary lines must remain open while the pump is runing.
• The pump has soft packing type stung boxes. These should drip during operation. The gland nuts
should only be lightly tightened. In case of excessive leakage from the stung box tighten the gland
nuts slowly and evenly until the leakage is reduced to the dripping state. Check the stung box for
overheating by hand. If the gland nuts can not be tightened any further remove the old packing rings.
Make sure that each packing ring is cut of correct size. The joint in successive ring should be oset
to each other.
• The flexible coupling elements should be regularly checked and replaced as soon as they are shown
signs of wear.
• Occasionally check the motor current. Stop motor if the amperage is higher than usual; there may
be jamming or friction in the pump. Make the necessary mechanical and electrical checks.
• Stand-By pumps should be run for a short time at least once a week to ensure they are in constant
readiness for operation. Check the integrity of auxiliary connections.
6- LUBRICATION
• Bearing of SDS type pumps have grease lubricated ball bearings.
• Life-time grease lubricated bearings are maintenance free.
• See the attached Table 4 for bearings type and size.
6.1- Application of Grease on the Bearing
High quality NLGI 2 or NLGI 3 grease must be used in bearings.
The grease must be replaced in every 12-14 months or at the end of each 3000 working hours.
More frequent grease replacement may cause overheating and shortening of the bearing life.
The bearings of the pumps demounted for repair must be inspected and replaced, if necessary.
It must be ensured that the greasing equipment and the reservoir are clean before adding grease to
the bearings.
Grease in suitable amounts must be added to the bearings.
The temperatures of the bearings may increase in the case of adding excessive amount of grease.
The temperatures of the bearings will decrease to the normal operating temperature when excessive
grease is removed.
• The pump must never run dry.
• Never run the pump for along period against a closed discharge valve (at zero flow)

7- DISASEMBLY AND REASSEMBLY
• Follow the safety precaution measures outlined in “safety instructions”.
7.1- Disassembly
•Close all valves in the suction and discharge lines, and drain the pump by opening the drain plug and the air
plug.
• Disconnect the stung boxes flushing pipes.
• Remove coupling guard and other safety guards (see section safety guard).
• Remove all casing main joint nuts and dowel pins.
•Separate the casing halves, lifting o the upper half casing. This reveals the pump internals (impeller, wear
rings) for inspection.
• Unscrew the bolts which are connecting the bearing housings to the bottom half casing.
• Remove bearing covers and bearing end covers.
• Pull the bearing housing o the bearings.
• Unscrew the shaft nuts and lock washers.
• Pull the bearing o the shaft and remove.
•Remove in sequence bearing covers, throwers, spacer sleeves, stung boxes, shaft protecting sleeves, wear
rings, impeller and impeller key.
• Clean all the parts, replace damaged or worn-out ones.
7.2- Reassembly
•Reassembly proceeds in reverse sequence to dismantling as described in (section 7.1). You may find the attached
drawing useful. the following points should be noted more particularly.
• Never use old o-rings and make sure the new o-rings are the same size as the old ones.
•Before mountling the shaft protecting sleeves inspect the condition of their rubbing faces. Use new sleeves if
the old ones are badly worn, scored or rough.
•the joint faces of the casing halves are sealed with liquid sealing compund. The joint faces should be thoroughly
cleaned before reassembly and coated over again with sealing compund. NEVER USE A PAPER GASKET BETWEEN
THE TWO FACES.
The following tightening torques must be taken into consideration when tightening
the bolts and nuts during installation.

7.4- Shaft Seal
7.4.1- Pump with soft packing gland
•While starting to change soft packing thoroughly clean the stung box and shaft (or shaft sleeve,
if used).
•Cut enough number of pieces suitable lenght diagonally from suitable size of soft packing. Roll it
up over the shaft (or shaft sleeve, if used) and see the ends are in full contact.
• Insert the first packing ring as the joint will place up, and press home using the gland cover.
•Place the second ring as joint will place down. Insert all the packing rings in the same way. If there
is a lantern ring put into place too.
•Place the gland and fully tighten, thus the packing rings will take the shape of stung box, the
loosen it. Slightly tighten by turning the shaft and stop tightening when it slightly brakes the shaft.
•After starting operation, it is necessary that water drips from the packing. This dripping shouldn’t
be less than 10 cm³/min and more than 20 cm³/min. Adjust dripping by uniformly tightening or
untightening the gland nuts slighly.
•Check the temperature of soft packing after two hours operation after gland adjustment to avoid
overheating.
