Floating Scroll Pump

Floating Scroll pump works under the same principal as the conventional Scroll. The pump consists of a fixed and a rotating scroll. The difference is the fixed scroll is allow to "float" with the rotating scroll. The two scroll are allowed to lightly touch each other. A dynamic balancing mechanism keep the contact to be mild and controllable at constant pressure. The benefit is obvious. It has No Tip Seal. Pumps moisture at higher rate.

The number one problem of a Scroll pump is the wear and deterioation of the Tip Seal. The floating Scroll pump does not use Tip Seal. The liability of seal wear is eliminated. No tip seal replacement is necessary.

4 stanadard sizes available:

SVF-5 (0.2 cfm), SVF-20 (0.7 cfm), SVF-50 (1.8 cfm) and SVF-100 (3.5 cfm).

The pump is 100% oil free and maintenance free. Very compact and ideal for portable equipment. It has been the prefer choice for medical application such as resperator system for patients. Common applications are for analytical instrument, laboratory, backing pump or anywhere clean vacuum is needed.

Larger size pumps are available. Higher vacuum pumps are also available upon request.

Features and Benefits:

The oil-free floating scroll pump has fixed first scroll and spining second scroll that floats. Seals are dynamically balanced to a slight touch but in full contact. This patented feature increases pumping speed for moisture at nearly no wear. Life of pump is extremely extended without requireing seal change.

Conventional Scroll pump requires seal replacement after 6 month of running. The Floating Scroll pump can run continuously for years without service requirement.
