What is a dry vacuum pump?
Dry vacuum pumps create vacuum without using oil in the pumping chamber. Because there is no risk of oil contaminating the medium or product being pumped, they are preferred in food packaging, pharmaceutical and laboratory applications, printing and paper machinery, CNC vacuum tables, and industrial processes requiring clean operation. As they do not require oil changes, their maintenance needs are generally lower.
Types of dry vacuum pumps
- Diaphragm vacuum pumps: Clean vacuum for low flow rate, laboratory, and analytical instrument applications.
- Dry vane vacuum pumps: Widely used in packaging and printing machinery with self-lubricating vanes.
- Claw type vacuum pumps: Offer high flow rate and durability with non-contact rotors.
- Roots type vacuum pumps: Used in applications requiring very high flow rates, usually in conjunction with another pump.
The m³/h value in product names indicates the pump's suction capacity.
Selection criteria
The required vacuum level and suction flow rate must be determined according to the needs of the application. If the air being drawn contains moisture, dust, or vapor, the pump's suitability for these conditions must be verified and a filter or separator should be added to the suction line. Continuous duty cycle, ambient temperature, and the pump's cooling method must also be taken into account during selection. The electrical supply (single-phase or three-phase) must be compatible with the facility's infrastructure.
Maintenance
In dry vane pumps, the vanes wear over time and must be replaced at specified operating hours. Intake filters should be cleaned or replaced regularly. The pump's cooling fins and fan must be kept free of dust. Unusual noise, vibration, or a drop in vacuum level is a sign that maintenance is needed.
Frequently asked questions
What is the difference between a dry and an oil-lubricated vacuum pump?
Dry pumps operate without oil; oil-lubricated pumps can generally reach a deeper vacuum but require oil maintenance.
Which pump for food packaging?
Dry vacuum pumps are frequently preferred because oil vapor cannot contaminate the product.
Can a Roots pump be used on its own?
Roots pumps are typically operated together with a backing vacuum pump.
How much vacuum does a diaphragm pump achieve?
The vacuum level varies by model; refer to the values in the product information.
When should the vanes be replaced?
It depends on operating hours and conditions; follow the manufacturer's recommendations.
Can humid air be drawn in?
Moisture can damage the pump; a separator or filter should be used at the inlet.
