The Atlas Copco 2901110800 Oil Pump Kit is a genuine service kit designed for compatible ZR and ZT oil-free compressors. Atlas Copco officially identifies the part as an “Oil Pump Kit for Oil Free Compressors”, and its product information lists a weight of approximately 1.11 kg.
Working Process
The 2901110800 oil pump kit is part of the compressor’s lubrication system. Its primary function is to provide controlled oil circulation to components that require lubrication within the applicable compressor assembly.
During operation, the oil pump draws lubricant from the designated oil circuit and delivers it through the required passages. This controlled circulation helps provide lubrication to moving components, while also assisting with heat management and reducing friction and wear.
The oil pump operates together with components such as the pump body, eccentric ring, seals, O-rings, pin and disc springs. Atlas Copco’s official component listing includes 2 disc springs, 1 pin, 1 oil pump, 1 ring, 1 eccentric ring, O-rings, a seal washer and a parallel key within the kit.
As the compressor operates continuously, proper oil circulation is important for maintaining reliable mechanical performance. A worn or damaged oil pump can reduce lubrication flow and potentially contribute to increased friction, temperature and component wear. Replacing the pump and associated wear components with the 2901110800 service kit helps restore the intended lubrication performance.
Application & Compatibility
Atlas Copco identifies 2901110800 as an Oil Pump Kit for ZR/ZT oil-free compressors. Atlas Copco’s regional product page also lists the part as “KIT OIL PUMP ZT15-50/VSD.”
Exact compatibility should be confirmed using the compressor model, configuration and serial number before installation.
