Xylem expanded its pump portfolio to include e-MP multistage ring section pumps, e-XC single-stage, double-suction centrifugal pumps and larger vertical turbine pumps. The pumps are designed to address issues in industrial pumping and processes, including minimizing downtime and environmental impact, and boosting and transporting water as efficiently as possible.

Advanced controller can accommodate up to 15 pumps and 8 cooling towers, including variable-frequency drives for each, outside programming from the factory or new software required.

Line of two-stage, oil-sealed rotary vane pumps range in flow rate from ~141 to 2295 ft3/hr (4 to 65 m3/hr). They are suited for use in analytical instruments and semiconductors as well as the chemical, vacuum coatings and power industries.

Specifically designed for challenging fluid-transfer applications, the TC-X500 is fitted with a heavy-duty, mechanically actuated shifting mechanism and non-centering, coil-spring-assisted air motor. 

Maker of nonmetallic sealless pumps has added a 316 stainless steel metallic sealless pump line.  The Iwaki Sanwa line will include two series of pumps. Series MP offers flows to 340 gal/min while the smaller Series MMP will be a fractional-horsepower offering with flows to 24 gal/min. 

The 25th IIR International Congress of Refrigeration (ICR 2019), which was held August 24-30 in Montreal, welcomed over 850 participants from 45 countries. The event also welcomed over 650 papers, nine workshops, 10 IIR Commission and Working Group meetings and four technical tours.

When sizing, selecting and installing hermetic pumps in refrigeration units, there are many considerations. This article will explore the types of pump as well as provide a guide for troubleshooting common problems.

The GP Series is available as water-cooled, air-cooled or remote air-cooled units. Air-cooled models, both local and remote, utilize microchannel air-cooled condenser coils.

Series MM have food-grade wetted materials and a construction that enables clean-in-place (CIP) and sanitize-in-place (SIP) capabilities. The pump design incorporates soft redirections without rotating parts and shaft seals in the product chamber.

In an effort to improve the accuracy of pump standards’ nomenclature, the Hydraulic Institute published new national standards combining its 1-series and 2-series standards into a single 14-series standards. Historically, HI standards have been divided into “1-series” standards — covering centrifugal pumps — and “2-series” standards — covering vertical pumps.
