MWI's rotary lobe pump, is a self-priming, valveless positive displacement pump - perfect for groundwater applications, including wellpoint dewatering. Available for purchase or rental, the Rotoflo™ is unrivalled in its ability to be repaired easily on-site. Its quick-release cover can be removed with conventional hand tools to give access to the inner parts of the pump without the removal of critical components.

Because of its inexpensive spare parts and low maintenance, the Rotoflo™ can be up and running in a fraction of the time, and yet it still costs less than comparable pump systems.

Why Choose the MWI Rotoflo?

Because the RotoFlo™ simply is the best combination of reliability, low operating cost, rapid onsite repairs, flexibility and performance of any wellpoint pump on the market.

• The Rotoflo™ is an unbeatable combination of a diesel engine, Funk drive and RotoFlo™ pumphead.
• It is simple and made up of extremely rugged and robust components.
• It has no air/water separation chamber with floats, compressors or vacuum pumps to operate, maintain, repair or worry about.

Automatic Priming and Repriming - Unattended Operation

Rotoflo™ primes and automatically reprimes without any complicated mechanisms. The positive displacement pumphead moves air and/or water with equal ease. The rotors used for construction dewatering are pulsation free. Water can easily be pumped against high heads, allowing long runs for discharge piping. Rotoflo™ units can run unattended for hours.

Low Operating, Maintenance and Repair Costs

The Rotoflo™ has low operating costs. It consumes minimal fuel, thanks to the combination of a highly efficient pumphead and a fuel efficient diesel engine. Parts are inexpensive.

Low Down Time - Lightning Quick Repairs

The RotoFlo™ is as rugged and reliable as a wellpoint pump can be. When repairs are required they can be done rapidly and easily on site. The lobe tips can be replaced on site in half an hour. All of the lobe tips and the mechanical seals can be replaced on site in less than three hours. The cast iron rotors with elastomer tips minimize the problems of chunking that occurs with solid rubber rotors.

You can be back up and running in a short time with minimal impact on job sites. Many wellpoint pumps require a trip back to the factory and thousands of dollars to get you up and running again. Not the Rotoflo™, it is the contractor's most reliable friend!

Highly Versatile and Adaptable

The RotoFlo™ is very versatile. It will pump almost anything from sludge to wastewater to molasses. Different rotor shapes, materials and tips are available for various applications. You get double duty with this pump.
