PIV Drive Identification

This is a typical identification plate found on P.I.V. Werner Reimers, Posirex, Stufenlos, and Posired variable speed drives, gearboxes and reducers. Most of this information is also found on another smaller identification plate affixed to a control lever inside the drive.
When ordering parts, replacement drives or resolving technical issues about the drive, we need to know the following information from the ID plate:
DRIVE TYPE: This is the type of drive. RZ0, AB0, A12 and U0 are examples of drive types, although, there are many, many, other types of drive designations.

SERIAL NUMBER: On Werner Reimers drives, the serial number usually the form of 123456 G1, where 123456 is the first part of the serial number and G1 is the second part of the serial number (some older Werner Reimers drives do not have a G suffix). Other examples are 355 640 G6, 412 045 G12, 512 233, G1, etc.

CHAIN (KETTE) TYPE: This indicates the type of chain found inside the drive. The chain type usually begins with a letter and is followed by a series of numbers and letters. Such as, Rb140, A233V, RB034, A335VQ, RC370, WK2484S. There are many other types of PIV chains available.

There are other fields on the ID plate which we normally do not use when ordering spare parts and replacement drives. We have included these definitions here for your information. N1 is the input RPM, N2 is the output RPM. P2 is the output power in kilowatts and M2 is the output torque in Newton-meters.
