From Blichmann Engineering:

The all new RipTide™ is the very first pump designed specifically for homebrewing!  We've solved the problems that have plagued homebrewers for years!

• High performance curved blade impeller and strong rare earth magnets deliver 7 GPM and up to 21ft of pressure head!
• Tri-clamp head connection fully disassembles in seconds for easy cleaning
• 1/2" NPT inlet and outlet connections
• Totally enclosed motor is splash proof and super quiet (50 dB)
• Integral linear flow valve for superior flow control - don't spend more money for a separate valve and fittings. ¬†A separate valve and fittings can easily cost you an additional $25-35!
• Integral air vent valve and partially enclosed impeller design allows you to prime the pump in seconds - no more frustrating air locked pumps!
• Stainless steel head rotates 360 degrees to fit in virtually any installation
• Large stable base with protective rubber feet keeps the pump from tipping - a $25 retail value included!
• Convenient power switch on the base
• Includes a 10ft long cord with plug (120V)
• Base acts as a cord wrap for convenient storage
• Assembled in USA from USA and imported components
