When a vacuum pump is delivered, the moment you open the door is the starting point of the arguments that may follow. If transport damage is not noticed at handover, responsibility becomes unclear. This article explains which checks to carry out when receiving a pump and how to document them.
Why the Moment of Delivery Matters
Carriers allow a limited time to record damage at delivery. This period is often short, and the driver or receiver must note a reservation on the delivery document. Spotting damage on the first day makes insurance and liability processes much easier.
A check at handover also shows that the pump was in sound condition before installation. If a fault occurs later, this document can separate damage sustained in transit from a problem caused during installation.
A vacuum pump shipment passes through many hands and vehicles from the factory to the site. On this journey the pump can face hazards such as drops, impacts, vibration and moisture. The moment of delivery is the point at which these risks first become visible. For this reason, receiving the delivery is not a formality but a critical check that establishes the responsibility of the plant.
A check made at the moment of delivery is the strongest evidence for deciding who is responsible for damage that appears later. In disputes between the carrier and the plant, the records made at delivery are decisive. If no record was made or it was incomplete, the responsibility for the damage stays unclear.
The people who should be present at the moment of delivery are also important. The maintenance officer, the purchasing officer and, if necessary, an operator should carry out the check together. Different points of view make it possible to spot missing and damaged items together. A check made by one person alone may miss details.
Preparation for receiving the delivery begins with a review of the shipping documents in advance. The model of the pump, the serial number, the parts list and the delivery note information should be kept ready to compare with the pump on site. This preparation allows the check to be carried out quickly and in an orderly way.
The external condition of the packaging is the first step of the delivery check. The crate, the pallet and the protective materials should be looked at for crushing, puncturing, wetting or tearing. Damage to the packaging is a sign that the pump inside may also have been harmed.
Checking Packaging and External Condition
When receiving the delivery, first examine the outer surface of the packaging. If there are signs of crushing, puncturing, wetness or shifting, note them on the document and photograph them. Packaging damage is the first sign that the part inside may also have been harmed.
On the pump itself, look for damage to the outer surface, bent coupling or junction box covers, cracks in the motor housing and loosened connection points. Impact marks from transport on the crate should also be recorded.

The packaging may carry marks showing that it was dropped during transport, signs of crushing at the corners or evidence of jolting. These marks should be photographed and recorded. Even if what is inside is not yet known, external damage on its own is a matter for a note.
The soundness of the seals and the tape on the packaging should also be checked. A crate whose seal is broken or which has been opened afterwards indicates that it may have been tampered with during the journey. In that case a report should be drawn up before the crate is opened.
In the external condition it is also important whether the packaging has been in contact with moisture. A wet or mouldy packaging increases the risk of corrosion of the parts inside. If there are signs of moisture, the carrier should be asked whether the shipment was handled in rainy conditions.
Comparing the delivery note with the parts list is the basic step of the delivery check. The quantity, type and model of each item must match exactly what is written on the delivery note. If a missing part is noticed only during assembly on site, the production of the plant can be seriously delayed.
When comparing with the parts list, accessories must also not be forgotten. Flanges, gaskets, bolts, sensors, cables and the user manual are as important as the pump itself. A missing sensor or gasket can stop the installation.
Comparing the Delivery Note and Parts List
Compare the items received one by one with the lines on the delivery note and the order document. The pump model, serial number, motor power and voltage should match the information in the documents. Also check whether accessories, filters, oil, gaskets and connection parts are missing.
If the serial number and the nameplate do not match the written documents, contact the supplier before accepting the shipment. This mismatch may mean the wrong product was sent.
Checking that the model and serial number match the information on the nameplate verifies the accuracy of the order. A wrong model or a different voltage class can prevent the pump from working or damage it. For this reason the nameplate information should be compared one by one with the order form and the delivery note.
Missing or surplus items should be written into the delivery report at once. This record forms the basis of the correspondence with the supplier. A shortage not written down at the time of delivery is much harder to prove when it is claimed some weeks later.
Hidden damage is damage that is not visible at the moment of delivery but has occurred during transport inside the pump. A blow can disturb the shaft alignment, damage a bearing or loosen an internal connection. Such damage often comes to light at the first start.
The internal check should be carried out after the pump has been taken out of its outer packaging. It should be checked whether the shaft turns freely when turned by hand and whether there is any friction or sticking. A smooth rotation is the first sign that there is no mechanical damage.
In the internal check after transport, the condition of the motor windings and their insulation should also be assessed. An insulation resistance measurement can reveal a leakage caused by moisture or mechanical damage. This measurement should be made before any energy is applied.
Hidden Damage: Internal Checks After Transport
Some damage cannot be seen from outside. Impacts during transport can cause deterioration in the bearings or shaft alignment. After opening the packaging, therefore, turn the shaft by hand to check that it rotates freely. Note any friction, catching or abnormal sound.
On oil-sealed pumps, also inspect the oil level and the condition of the oil. If water or foreign matter is seen in the oil, this may indicate a leak during transport or internal damage.
On oil lubricated pumps, the oil level and the condition of the oil should also be checked during the internal check. Signs of an oil leak, contamination or seepage may point to damage that occurred during transport. If an oil change is needed, this should be added to the delivery report.
Detection of damage after delivery usually comes out during the first commissioning on site. For this reason the first start should be made with careful observation and for a short time. Sound, vibration and temperature values should be monitored in order to catch the signs of hidden damage early.
Taking photographs is one of the most valuable steps of the delivery check. All four sides of the packaging, the damaged points, the delivery note and the parts labels, and the serial number of the pump should be photographed. Photographs provide much more convincing evidence than a written description.
When taking photographs, it should be made sure that each image carries a date and time. To show the size of damage, a reference object such as a measuring rule or a coin can be placed beside it. These small details greatly ease any evaluation made later.
The delivery report forms the official record of the check. The report should contain the date, the time, the names of the person receiving and the person delivering, the pump information, the items checked and the damage found. The report should be signed by the parties and one copy kept.
Photos and Delivery Report
For each damage, take two photographs: one of the overall view and one close-up. Make sure the date and location are visible in the photos. The delivery report should state the type, location and size of the damage, and the time it was found.
Sign the report together with the carrier's driver. If the driver refuses to sign, note this on the report and inform the responsible person immediately.
Each damage written in the report should be described in clear and precise language. The location of the damage, its type, its size and the number of its photograph should be stated. Vague wording weakens the report in a later objection and makes responsibility unclear.
While the report is being prepared, the driver or representative of the transport company should also be present. The carrier's signature means that it accepts the damage was seen at the moment of delivery. If the carrier is not present, this should also be noted in the report.
The first step after acceptance is entering the pump into the record system. The serial number, model, delivery date and warranty information form the first lines of the maintenance record. Without this record the ownership and history of the pump on site remain unclear.
After acceptance, the pump should be stored in a suitable place. A dry area protected from dust and free of the risk of impact should be chosen. Until installation, the packaging of the pump should not be left open and the connection points should be closed.
One of the first steps after acceptance is to review the warranty conditions. The warranty period, the exclusions and the notification procedure allow quick action when a problem appears. This information should be kept where everyone in the team can reach it.
First Steps After Acceptance
If damage is found, complete the acceptance with a written reservation and notify the supplier formally as soon as possible. If there is no damage, keep the pump in a protected environment until it reaches the installation area, and store the packaging and shipping documents for future use.
The delivery records are the first documents that will be used throughout the life of the pump. File them together with the commissioning report and the maintenance calendar.
At the end of the delivery process, the notification to the supplier should also be planned. Claims about missing or damaged items should be sent in writing together with a copy of the report. A notification made in time is the most important step in protecting rights.
Finally, the results of the receiving process should be recorded in an assessment. Information such as how much damage each carrier caused and which supplier packs most carefully can be used in future supply decisions. This feedback helps the supply chain improve over time.
