Screw pumps

Schreiber incorporates the Archimedean screw pump concept in the Tube-Mounted Screw Pump and Open-Flight Screw Pump. The concept provides variable capacity at a constant speed up to a design maximum. The Tube-Mounted Screw Pump transports liquid inside a stationary tube, simplifying structure and eliminating grouting. The units are factory assembled. Pumps can be set at a fixed angle or the lower end can be supported by a hoist to vary the pump angle and for maintenance access.

The Open-Flight Screw Pump transports liquid using a concrete trough. This non-clog pump is typically installed at a 30- or 38-degree angle. The pump has a variable capacity at a constant speed up to its maximum. Pumps use a single-row spherical roller, self-aligning, combination radial/thrust lower support bearing with a minimum L-10 life of 100,000 hours.

Lower bearing lubrication requires only a transparent oil reservoir and feed tube to provide oil by gravity, without pressurized grease systems. A simple pillow block or flanged bearing provides radial support at the upper shaft. 205/655-7466; www.schreiberwater.com.
