The only problem with street use is that the extra usage tends to wear the pumps out quicker than race only applications. We tell people that run them on the street to make sure that they have some oil running through the pump to get the best life. At low rpm's on the street you just don't have the same volume of air and oil running through the pump and that tends to wear the pumps out prematurely. We now have a street kit that recirculates oil through the pump to make it live a lot longer during low RPM operation.
The last pump that GZ Motorsports offers is the daddy of them all-the Super Pro vacuum pump. With a newly designed polished aluminum case, this pump features carbon fiber vanes with extra tough Rulon wipers for that perfect seal. Just like the other pumps GZ Motorsports offers, the Super Pro pump has oil mist passing through it and there are no cleaning requirements associated with this pump. At , this is the largest and most potent vacuum pump offered by GZ Motorsports, delivering 24 inches of vacuum and producing 33cfm at 5,090rpm.
Place the lower end of your siphon tube into the BOTTOM of the receiving (empty) container. Hook the other end to your sterilized auto-syphon. Hold your auto-siphon in the middle of your liquid-filled container. DO NOT rest the auto-siphon in the sediment on the bottom of the fermenter. Pump your auto-siphon a few times, and the liquid should begin to flow into the bottom of the receiving container. As the liquid drops out of the filled container, move the bottom of your auto-siphon lower to keep it submerged. Eventually, you can tilt the draining container into a 45-degree angle, and suck the pooled liquid off of the "pancake batter" sludge that covers the bottom. If you happen to vacuum up some of the sediment, do not worry - it will settle out in the secondary. That's it.
