Screw Pumps

Centex Fluid Products proudly distributes Schrieber Water Screw Pumps. Schreiber incorporates the Archimedean Screw Pump concept in both the Tube Mounted Screw Pump and the Open Flight Screw Pump. This concept provides variable capacity at a constant speed up to its design maximum.

The Tube Mounted Screw Pump transports liquid inside a stationary tube, simplifying structure design and eliminating the need for grouting. The units are completely factory assembled, which minimizes installation costs. Pumps can be set at a fixed angle or the lower end can be support by a hoist to vary the pump angle and for maintenance access.

The Open Flight Screw Pump (OFSP) transports liquid utilizing a concrete trough. Truly a non-clog pump, the OFSP is typically installed at a 30 or 38 degree angle of inclination. The pump has a variable capacity at a constant speed up to its maximum.

Schreiber’s screw pumps utilize a unique single row, self-aligning, combination radial / thrust lower, spherical roller support bearing with a minimum L-10 life of 100,000 hours. The lower bearing lubrication system is simple and reliable by requiring only a transparent oil reservoir and feed tube to provide oil by gravity, without elaborate pressurized grease systems and their inherent operational concerns. A simple pillow block or flanged bearing provides radial support at the upper shaft.
