The steel lined plastic water circulation vacuum pump mainly replaces the original PP and PPH water tanks with steel lined PE and PTFE water tanks. This not only makes the water tank corrosion-resistant, but also has better strength and temperature resistance, greatly extending the service life of the equipment, reducing the failure rate of the equipment, and making the vacuum degree more stable. It can also be equipped with a graphite modified polypropylene tubular condenser to ensure that the circulating water temperature in summer is in a suitable range and the vacuum effect is more ideal. This device can be customized according to customer requirements, with two or more vacuum pumps connected in parallel. The entire machine has a channel steel base and is easy to lift and install on a platform and seesaw. It can be equipped with Roots pumps to achieve higher working vacuum.

The steel lined plastic water circulation vacuum pump combines the strength of steel structure with the corrosion resistance of plastic material, and its advantages are mainly reflected in the following aspects:

Strong corrosion resistance: The steel lined plastic water circulation vacuum pump effectively isolates corrosive media from direct contact with metal by lining the steel casing with a plastic layer. The plastic layer is usually made of corrosion-resistant materials such as polyethylene (PE), polypropylene (PPH), or tetrafluoroethylene, which can resist the corrosion of chemicals such as acid, alkali, and salt, extend the service life of equipment, and reduce maintenance costs.

High structural strength: The steel casing provides excellent mechanical strength and rigidity for the pump body, capable of withstanding high pressure and impact forces. This structure not only ensures the stability of the pump body in high-pressure environments, but also avoids deformation or cracking problems caused by insufficient strength of the all plastic pump body.

Good sealing: The steel lined plastic water circulation vacuum pump adopts special welding and rolling molding processes to tightly bond the steel body with the plastic layer, forming a seamless and leak free overall structure. This design effectively prevents medium leakage and improves the operational safety and environmental friendliness of the equipment.

Excellent temperature resistance: The plastic lining layer has good temperature resistance and can maintain stability within a certain temperature range without softening or deformation due to temperature changes. This makes the steel lined plastic water circulation vacuum pump suitable for applications that require high or low temperature environments.

Long service life: Due to the combination of the strength of steel structure and the corrosion resistance of plastic material, the overall service life of steel lined plastic water circulation vacuum pump is significantly better than that of a single material pump body. Reduced the failure rate and replacement frequency of equipment, and lowered long-term operating costs.
