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.

When compared to space cooling, process cooling — or the removal of heat from the fluid that serves water-cooled equipment used in a manufacturing process — is a bird of a different feather. Interesting though — and the source of some fascination among those in the cooling trade — is that much of the equipment, tools and techniques remain the same.

Advanced controller can accommodate up to 15 pumps and 8 cooling towers, including variable-frequency drives for each, without programming from the factory or new software required.

The design of the Novaplex Vector process triplex diaphragm pump reduces the installation footprint by arranging pump heads in three dimensions. The arrangement of the heads also reduces the number of crankshaft bearings from six to two, compared with traditional triplex pumps.

A portable, clean-in-place pump system, Model GDS-100 is suited for larger descaling cleanings to remove limescale, calcium and mineral deposits, rust and other contaminants found on process manufacturing equipment.
