Spare Parts and Repair Services for Industrial Vacuum Pumps
Hop Nhat HCM Air Compressor Company specializes in supplying spare parts, maintenance materials, repair services and overhauls for industrial vacuum pumps. We support various oil-lubricated and oil-free vacuum pumps from brands such as Busch, Becker, Leybold, Elmo Rietschle, Edwards, ULVAC, Atlas Copco, Agilent, PVR, DVP, Pfeiffer, Gardner Denver, Nash, Tuthill Kinney, Robuschi, Woosung, Orion, Gast, Thomas, Value, EVP and many other brands.
Spare parts are selected according to the brand, pump model, part number, installation dimensions and actual operating conditions, helping the pump maintain a stable vacuum level, reduce operating temperature, minimize oil mist emissions and extend the service life of the pump assembly.
Technical Note: The model list in this article was compiled from the spare parts documentation. Before placing an order, the old part number, serial number, dimensions and actual images of the pump should also be checked.

Types of Vacuum Pump Spare Parts Supplied by Hop Nhat HCM
1. Vacuum Pump Oil Separators
An oil separator, also known as a vacuum pump exhaust filter, oil mist separator or oil demister element, is installed inside the exhaust chamber of an oil-lubricated rotary vane vacuum pump.
This component performs the following functions:
- Separates lubricating oil from the exhaust air.
- Recovers oil and returns it to the circulation system.
- Minimizes oil mist emissions into the working environment.
- Reduces vacuum pump oil consumption.
- Maintains stable exhaust pressure and operating temperature.
When the oil separator becomes clogged, the pump may experience high operating temperature, increased motor current, oil smoke at the exhaust outlet, abnormal oil consumption or reduced pumping capacity.

2. Vacuum Pump Oil Filters
The oil filter removes metal particles, dirt, carbon deposits and other contaminants from the circulating oil. Clean oil filters help protect:
- Bearings and rotor surfaces.
- Vanes and the pump chamber.
- Lubricating oil passages.
- Oil return valves and sealing components.
Using an oil filter with an incorrect flow capacity or an unsuitable bypass valve opening pressure can reduce lubricating oil flow, causing the pump to overheat, wear rapidly or seize.
3. Inlet Air Filters
The inlet air filter prevents dust and contaminants from entering the pump chamber. In production environments containing paper dust, wood dust, plastic powder, food-processing dust or metal-machining particles, regular inspection of the inlet air filter is particularly important.
A clogged air filter reduces pumping capacity, increases vacuum evacuation time and forces the pump to operate continuously under high load.
