Service parts

indentiﬁcation

Use this information and procedure to identify the module group, item number, manufacture date,

part number, and part name of parts included in the LPV closed circuit pump. Use the parts listed

when performing minor repairs, major repairs, or conversions on LPV closed circuit pumps.

Nameplate

General information

Each unit has a nameplate aﬃxed to its housing.

The nameplate includes this information:

Model Code

The Danfoss model code deﬁnes the speciﬁc

unit. Use it when ordering parts to service this

product.

Model Number

The manufacturing factory uses Danfoss’ model

numbers. On repeat orders, order a complete

unit by the model number.

Serial Number

The Danfoss serial number identiﬁes the

manufacture date and unit sequence in the

build. The serial number also identiﬁes the unit’s

warranty time period.

The letter code indicates the location of original

manufacture (assembly). A indicates the unit was

originally assembled in Ames, Iowa, USA.

The ﬁrst number (2 digits) indicates the year of

manufacture. (06 would indicate the unit was

manufactured in 2006).

The second number (2 digits) indicates the

calendar week of manufacture.

The third number (5 digits) is a sequential

number used to identify a speciﬁc unit.

General information

Date code

The date code is deﬁned as the year and week of manufacture. The same item number may list more

than one part number. This indicates that there is more than one conﬁguration for that item number.

You will see that there are diﬀerent date codes for the diﬀerent part numbers. Find the date code of

your unit from the nameplate to determine which service part number you need to order.

EXAMPLE: The service part desired is Item C090

All units using this order code with a date code of 94-34 and up to and including 98-01, must use part

number “4570025”. All units with a date code of 98-02 and newer must use part number “4570245.”.

Service bulletins

A Service Bulletin Number (SB-_ _ _ _ - _ _ _) may follow the “Part Name” of the part you desire. You

must read that Service Bulletin prior to ordering that part. The information contained in these Service

Bulletins, as of the print date of this bulletin, are included at the end of this manual. Service Bulletins

contain more detailed information such as interchangeability, what additional parts are involved, etc.

It is suggested that you add additional Service Bulletins to this manual as you recieve them.

Procedure to identify a part General

The modular design of LPV units results in a simpliﬁed service parts list and part number

identiﬁcation procedure.

The same item numbers are used for same part names on all units within a product type. (Example:

The lip seal - Item D01 has the same item number on all motors.)

A part number that has another number following it in parentheses is done to make this a world wide

manual. The ﬁrst number is sold in Germany. The number in parentheses is sold in the United States.

(Example: 688622 (9004700-1907), customers would order 9004700-1907 if ordering the part in the

United States.)

Example of a Part Identiﬁcation

The nameplate on an LPV pump has an Order Code of LPV 035 E3 B A C C A G A A BFF DS F FF A NNN.

Use the following procedures to determine the part number of the input shaft used on this pump.

1. Referring to the input shaft module in the Order Code (see page 7), the input shaft option for this

pump is identiﬁed by the code “C”. (LPV 035 E3 B A C C A G A A BFF DS F FF A NNN).

2. Referring to the Service Parts List, ﬁnd the shaft group. Next ﬁnd the order code that relates to this

unit, which is “C”. The shaft is found to be item E01 and part number 4250202.
