The Open Flight Screw Pump transports liquid utilizing a concrete trough. Truly a non-clogging pump, the Open Flight Screw Pump is typically installed at a 30 or 38 degree angle of incline. The pump has a variable capacity at a constant speed up to its design flow.

The Tube Mounted Screw Pump transports liquid inside a stationary tube, simplifying structural design and eliminating the need to grout. The units are completely factory assembled and self contained, minimizing installation cost. The pumps can be set at a fixed angle, or an optional hoist can be provided to vary the pump angle, allowing for pumping rate changes and easy maintenance. The pump provides a variable capacity at a constant speed.
