Allweiler to Roll Out New Centrifugal Pumps

Allweiler GmbH, part of CIRCOR International, Inc., will exhibit its redesigned vertical centrifugal pump solutions for ship engine rooms at this year’s SMM fair in Hamburg.

According to the manufacturer, a new innovative foot design reduces space requirements and improves operational safety.

"The new compact MA-S and MA-C series are vertically installed centrifugal pumps with axial inlets and radial outlets. The S version was designed for simple and rapid assembly and disassembly of the insert unit with impeller. The C version offers the same reliability with a significantly shorter installation height, so it's perfect for customers with severe space restrictions," explained Christian Martin, Senior Director Product Management.

Both versions use a new and patented foot design and have a footprint that is up to 23 percent smaller than the predecessor model. In this shorter, lighter version, the suction flange was redesigned with integrated fixing holes for pedestal mounting on the ship's foundation.

Allweiler said this arrangement extends the pump's service life and reduces wear to the bearing and shaft seal by directing forces from the pipeline directly into the foundation. It also helps avoid damages at the impeller and casing.

The company will also use the SMM show to introduce the redesigned "sister series" MI-C and MI-S with an inline volute casing.

The new products give shipbuilders an even greater range of pumps for moving freshwater, seawater, condensates and oils. These pumps are used primarily as cooling water pumps or as fire-fighting, bilge and ballast pumps.

In addition to the Allweiler pumps, the PV 6311 straight-way valve from Regeltechnik Kornwestheim GmbH (RTK) will also be presented at the Allweiler booth at SMM. Like Allweiler, RTK is part of CIRCOR's broad portfolio of market leading brands and specializes in control and stop valves.
