Should spare parts be specified in the mechanical pump technical agreement?

Our company requires spare parts to be available for 2 years when signing contracts

The spare parts provisions in the technical agreement must specify that the quantity should be as follows: 1 spare part for each vulnerable component (such as shaft sleeves, machine seals, O-rings, buffer rings, flange rings, impeller back caps, etc.)； Non-vulnerable parts (impeller, shaft): 2 in stock and 1 as spare. 2. Bearings are purchased from the market. 3. It is also necessary to consider the number of similar devices available in this factory when making a decision

The seller is required to provide, in the technical agreement, spare parts for commissioning as well as a list of spare parts for two years; the spare parts for commissioning are supplied together with the unit, while it is up to the owner to decide whether to purchase the spare parts for the two-year period.

According to international practices, spare parts should be specified; API610 provides details on the spare parts required for startup and those needed for one year.

Generally, large companies* carry spare parts with them, while some smaller companies prefer not to. The funds for spare parts included with the pump are counted as fixed assets, while purchases made later are classified as materials; there is a significant difference in terms of accounting.

As is standard practice, installation spare parts, commissioning, and two years’ worth of spare parts should be provided. Reputable large companies will proactively include this item in their design documents.

The random spare parts ordered at the time of purchase are mainly those consumable parts that are needed to ensure the proper operation of the machine within 1 to 2 years after it starts operating. For those spare parts that are of high value and not likely to get damaged in the short term, there is no need to include them in the technical agreement (after all, spare parts cost money). Of course, if you don’t mind having capital tied up in inventory or require very high reliability of certain machines, then they can be included in the agreement. Of course, you can also determine the purchase time based on the machine’s operating condition and make the purchase on your own.

It should be stated that a guarantee is provided: 1. Spare parts will be available in the future； ⒉Check the standards, find the spare parts, without affecting production ； ⒊It is beneficial for testing manufacturers’ product quality.

There should be a list of spare parts for vulnerable components for 2 years, right?:)

Logically, when purchasing equipment, the seller should take the completion and delivery point to be when the trial operation on site is successful; all costs up to that point are the responsibility of the seller. In other words, test run spare parts must be provided, while spare parts for the following year or two are another matter. If necessary, it must be specified in the tender specifications; the bid price should include the cost of spare parts, otherwise it will only cover low-value consumables. One thing to keep in mind is that the cost comes from the sheep; no matter how many spare parts there are, the money is paid by the buyer. So it needs to be clearly stated in the agreement. Moreover, the technical agreement is an essential part of a business contract and carries the same legal validity; otherwise, in case of any disputes, it is the agreement that counts, as verbal agreements hold no weight.

I have been working on organizing information related to spare parts recently. I believe it is essential to specify which parts are vulnerable to damage and to include information on spare parts for a period of two years when making purchases. Additionally, manufacturers should provide detailed specifications in accordance with national standards, so as to avoid unnecessary complications in future procurement processes.

A contract is a matter between the two parties; it needs to be written only if the buyer requires it, otherwise not.

For writing purposes, the technical documents of the pumps in our equipment include specifications and names of spare parts, etc

It should be specified which spare parts they are, as well as the age of those spare parts; they are provided along with the goods

Our company’s approach is to add whatever the client desires; after all, the cost is borne by the client themselves

I personally consider this to be very necessary; it is recommended that it be specified in the seller’s scope of supply as outlined in the tender documents. Spare parts should be quoted separately and must be included in the total price, with those that are more expensive needing to be listed in the tender documents. First, it facilitates bid evaluation; second, it makes it easier to decide whether to make a purchase, thus simplifying contract negotiations! ! For details, please refer to the format of the centrifugal pump tender documents below: 3. Scope of work and supply 3.1 Scope of supply Note: (1) Those marked with “1” represent the scope of supply by the seller. (2) Options marked with “*1” are those for which the seller is required to provide a separate quote. (3) The specific scope of supply shall be finally confirmed by both parties in the contract and is not limited to the items listed below. 1 Centrifugal pump main unit 1 Motor and junction box 1 Common base (unless otherwise specified) 1 Nameplate and bracket 1 Coupling and guard 1 Auxiliary pipelines and flushing pipelines within the base area (including valves, orifice plates), heat exchangers and liquid storage tanks (if any) 1 Shaft seal system 1 Lubricating oil system (if required) 1 Control and instrumentation, instrument connections, instrument electrical wiring and conduits (if any), instrument junction box 1 Shell discharge pipe and valve 1 Flange pairs and connection bolts, nuts, gaskets at handover points 1 Foot bolts, nuts, gaskets 1 Spare parts for installation and commissioning *1 Spare parts for two years of operation (quoted item by item) (must include but are not limited to the following): Serial number, Part name, Unit, Quantity, Remarks 1 Mechanical seal assembly, 2 sets 2 Bearing assembly, set 2 3 Throttling sleeve, set 1 4 Impeller mouth ring, set 1 5 Wear-resistant ring, set 1 1 Special tools (if any)

We all write down driving and spare machines on standby

The spare parts for two years are also listed, but they are generally not purchased and are not included in the total price; the spare parts that come with the product are included in the overall quote
