China High Performance Vacuum Pump Single-Stage 5 Pa Rotary Vane Economy Vacuum Pump Suppliers, Factories

The vacuum pump for refrigeration equipment is a device used for evacuating the refrigeration system. Its main function is to extract air, moisture, and other non-condensable gases from the system during the installation, maintenance, or operation of the refrigeration system, bringing the system to a certain degree of vacuum. This can prevent these gases from forming a layer of non-condensable gases within the system, which would affect the heat exchange efficiency. At the same time, it can also avoid the situation where moisture freezes at low temperatures and causes pipeline blockage, as well as prevent impurities such as air from corroding the components of the refrigeration system and other adverse effects, ensuring the normal operation of the refrigeration system.

Frequently Asked Questions

What is the difference between a single stage and a dual stage vacuum pump?

A dual-stage vacuum pump uses two rotors and chambers in series to achieve a significantly deeper vacuum level (ultimate vacuum down to 15 Microns) compared to a single-stage pump (ultimate vacuum around 150 Microns). This makes dual-stage pumps ideal for applications requiring deep and clean system evacuations.

What applications are these vacuum pumps suitable for?

They are highly versatile and suitable for a wide range of industries including HVAC OEM setups, family homes, food and beverage processing, industrial boilers, industrial utilities, temperature control systems, and washing & cleaning operations.

How does the anti-suckback design benefit the equipment?

The anti-suckback mechanism prevents the vacuum pump oil from flowing backwards into the vacuum chamber when the pump stops running. This ensures your vacuum systems and processed products remain clean and free from oil contamination.

What are the benefits of the aluminum alloy casing?

The aluminum alloy casing provides a durable, robust, and lightweight shell. It effectively dissipates heat during continuous operations while protecting internal components from heavy-duty industrial wear.

What voltage ratings do these vacuum pumps support?

These vacuum pumps are designed for global adaptability, supporting dual-voltage configurations from 110V to 220V, allowing flexible deployment across different power grids.
