2.1 Inspection
Inspect pump upon receipt for shipping damage and that all components are in the received assembly.
2.2 Storage Procedures and Recommendations
To store the pump:
•VOGT recommends indoor storage. Exposed seals may age for a considerable time. Protect pumps from heat and
exposure to solar radiation (ozone) or environmental contamination.
•If stored outdoors, protect equipment from temperature extremes, humidity, exposure to dust, moisture and vibration.
For outdoor or excessively unfavorable environments, including dust and rain, cover the equipment with some type of
protective sheeting to allow air circulation.
•Rotate the pump shaft at least 10 revolutions once a week.
•Keep discharge flange covers on during storage. Removal of the protective covers may allow foreign material, water or
substances harmful to the pump to enter and damage and/or crack the components.
•All external machined surfaces are factory coated with a rust inhibitor prior to shipment. Maintain protective coating on
machined surfaces.
•Maintain written records of shaft rotation intervals when storage period exceeds six months from time of shipment.
Records should be available for inspection by VOGT personnel.
•Maintain the oil level at the maximum level in the oil chamber.
•Rotate the shaft 10 turns once a week. If pumps are stored for more than 18 months from time of shipment, records
must be kept of the above storage activities to maintain all warranty provisions as agreed with VOGT.
•These provisions apply only to components and/or equipment owned by VOGT.

2.3 Medium-term storage (less than 2 months)
Perform the following:
1. Indoor storage is recommended.
2. The pump should be stored in an upright position. Although the pump can be shipped on its side.
3. The pump should be stored in a clean, dry place and should be protected from dirt and foreign matter. The storage
area should also be free from vibration.
4. If the pump is to be stored outdoors, it should be protected with a waterproof cover. However, the cover should not
seal the pump because air circulation is necessary to prevent condensation.
5. Rotate the shaft several 10 turns every week and inspect the general condition of the pump and equipment.
6. Before putting the equipment into operation, the watertight seal of the power cable should be checked.
7. Before putting into operation, the insulation should be measured if the equipment was exposed to wet storage
conditions.
2.4 Long Term Storage (greater than 2 months)
For safe storage and maintenance of new and standby pumps:
•Do not stack other pieces of equipment on top of the pumps.
•Repair any paint damage before storage caused by shipping damage.
•Flush pumps with clean water when removing a pump from service for storage. Remove any solids
accumulated on any of the seals.
•Dry any water present inside.
•Rotate the shaft 10 turns every week and inspect the general condition of the pump and equipment. Maintain
written records of shaft rotation intervals when the storage period exceeds six months from the time of
shipment. Records should be available for inspection by VOGT personnel.
•Do not store bearing carriers near areas that exhibit vibration or in dampness.
•Drain and completely refill the oil chamber every six months with new recommended lubricant.

General
Installation
Recommendation
General Installation
Recommendations
•Verify that all discharge line bolts and brackets are tight.
•Remove the protective cover from the discharge flange.
•Verify that the shaft is not off-center with the pump in the vertical position. Use an indicator placed as close to the
impeller as possible. Runout (TIR) should not exceed 0.003" (0.075 mm).
•Check the level and quality of the oil in the mechanical seal chamber, making sure that the seal faces have sufficient
lubrication. The level should be above the bottom plug, as shown in the parts list in this manual. If the oil level is low,
refer to the OIL CHANGE Section.
•If your VOGT "SSD" type pump is supplied with a cooling jacket, connect the external cooling water lines to the cooling
jacket. refer to cooling water requirements.
3.1 Pump Location
It is very important that the lifting aids for the removal and subsequent maintenance of the pump are operational.
3.2 Pre-installation
It must ensure that the cooling water lines do not freeze.
-The "SSD" type pump should be placed at the bottom of the sump relatively flat on its suction head.
-Avoid freezing of water in the pump or discharge line.
3.3 Discharge Line
The discharge piping should be connected to the discharge flange of the pump in such a way that the deformations
transmitted to the flange are minimized or by means of a hose to the discharge elbow nipples by means of hydraulic clamps.
We recommend that the discharge piping from the pump to the surface be of the flexible (hose) type for pumps with a
discharge between 2" and 5". For pumps with a discharge of 6" or more it is recommended to drive to the surface with rigid
piping. It is also recommended that all above grade piping be permanently installed and adequately supported.
The pump is supplied with an adapter elbow (flange/spigot) or companion flange.
3.4 Controls
Check the status of the control panel of the installed pumps. Humidity and temperature sensors.
Probe type level controls are recommended for pump lengths greater than 1,500mm.

Start-up
4.1 Recommendations before start-up
•Check electrical specifications, voltage, partition, amperage ratings, motor frequency, among others.
•Visually inspect all electrical connections to the motor and control signal wires.
•Verify direction of motor rotation.
•Verify that the pump rotates freely, without obstruction.
•The impeller is factory set with minimum clearance between impeller and suction housing.
•Check that all mounting brackets, external nuts, bolts and fittings are secure and that discharge piping is tight and
secure.
•Verify that the pump is fitted with the lower suction basket.
•Verify that the bilge or sump is free of items that could enter and/or obstruct the pump or suction basket.
•Set maximum and minimum bilge levels for pump operation.
•Connect cooling water line.
•Make sure that the power and signal cables are attached to the discharge piping, preventing them from hitting
against any element that could damage them while the equipment is in operation.
4.2 Recommendations in Start-up
•Check that the fluid temperature does not exceed the maximum allowed 40°C.
•Before operating the pump, the pump cooling water system must be put into operation.
•Start submersible pump.
•Monitor flow and pressure conditions and check against the curve data provided by VOGT.
•Monitor humidity and temperature signals.
-The engine cooling water system should never be stopped before the pump is stopped.
-It is recommended to flush the pump with clean fluid, and remove it from the pool so that it is not
clogged when the operation is stopped.

Maintenance
•Periodically measure the supply current voltage to verify that the pump is operating at the correct voltage.
•The electrical resistance of the motor should be checked at least once a month. If the resistance of the motor is less than
100M Ohm, the winding of the electric motor should be dried and the tightness of the wires, etc. should be checked.
•The oil capacity in the bottom cover should be checked every 500 hours. Therefore, place the pump horizontally. If necessary,
add oil as specified in the technical characteristics table of the pump through the opening provided for this purpose.
•If the presence of water is established in the oil (whitish emulsion), or if the oil contains solid particles (mud, etc.), it means
that the seals are defective. Their replacement is required.
•The amount of oil in the lower pump casing is specified in the pump's technical specifications.
•If the pump flow is decreasing, the clearance between the suction disk and the impeller should be checked. The recommended
clearance is given in the pump technical specifications.
