Pump Technology News

Food Engineering has published an exhaustive essay on pump selection, aimed at facilities looking to replace pumps that are either at the end of their lifecycles or pushing maintenance costs sky-high. The magazine interviewed several industry experts to learn about, among other selection criteria, viscosity of the pumped fluid and the types of solids present; sizing pumps based on required flow rates and other parameters; and identifying pumps able to handle several types of products on the same processing line. "Anyone responsible for specifying the best pump for any application must go beyond tradition," says one industry executive, who proceeds to explain just what that means.

Pfannenberg's new PWS Series Air/Water Heat Exchangers can use available water to efficiently maintain pump drive enclosure temperatures regardless of ambient. All models are UL-Listed with available Type Ratings of 12/3R/4 and 4X stainless steel (for washdown or harsh environments) and capacities to 10,000 W. Contact us for more information.

Custom engineered duplex and triplex plunger pumps with stainless steel or ceramic plungers. Pumptec offers duplex pump/motor sets that perform up to 1200 PSI and 4 GPM. Arimitsu triplex pumps offer up to 24,000 PSI and 392 GPM. Together, we are leaders in the carpet extractor, car wash, sprayers, and chemical injection industries and the strength of these pumps is unparalleled.

Up to 30% less power consumption than competing technologies with full control over the stroke and speed — the Umbra Force-Drive Actuator affords positive displacement pumps new performance capabilities. Contact the Umbra Group to learn how to integrate these devices into your applications.

The Vaughan Vertical Wet Well Chopper Pump solves pumping problems for industries such as chemical, wood products, steel, food processing, and municipal. The combination of the Chopper Impeller Design with the patented Seal-and-Bearing System has led to warranty costs among the lowest in the industry, with applications among the toughest.

These new drainage and sludge pumps boast a slew of upgrades that deliver new levels of functionality. Submersible pump features include wear-resistant impellers, better air valves for dry-running duty, and a metal housing designed to optimize heat transfer. A motor-protection feature cuts power off when operating temperature exceeds limits.

Water treatment works have begun to utilize a new source of renewable power generation — replacing pressure-reducing valves with rotary lobe pumps. As told by Pumps & Systems, the pumps, installed with variable-frequency drives, convert up to 70% of reduced pressure energy into electricity. The article describes a UK municipality that commissioned a lobe-pump system in December 2011.

Engineers specifying paint-finishing systems will want to take a look at these electric-drive circulating pumps that maintain constant fluid pressure, like pneumatic pumps. As a result, users will enjoy more consistent finishes. Opt for the advanced model and gain a digital control module capable of managing several pumps.

Use these twin screw pumps for the most challenging applications. Double-suction models get the call for transferring low-lubricity fluids. Use single-suction designs to pump viscous lubricating fluids like bitumen and residual oil. Lastly, multi-phase pump models shine in medium- to low-pressure applications in oil and gas production fields. Here's how they work.

This series covers how VSDs can be used to accommodate duty cycles with variable flow and head and applications to avoid. Topics include energy optimization, life cycle reduction, single-phase to three-phase power conversion, and inrush current reduction. Participants earn 4 PDH credits for attending the series. Series begins June 6th.

Cat Pumps can reduce methane emissions by more than 30% and lower maintenance costs. Triethylene glycol dehydration is the most common method of removing water from natural gas. Cat Pumps' specially-modified pumps, using a proprietary seal design, are engineered to run in the most demanding and heavily-used dehydration systems.

LEWA ecoflow® sanitary/hygienic-the most advanced metering pump in the world offering maximum safety for production and the environment during production of food or pharmaceuticals. Ideal solution for your application can be configured from an abundance of standardized assemblies. LEWA does this by combining different drive units and pump heads.

The VISCOFLUX lite drum emptying system is used to transfer higher-viscosity media which are just capable of flowing, out of ISO drums with lid, e.g. greases, adhesives and paint binders. Like all systems of the VISCOFLUX family, the VISCOFLUX lite leaves just less than 1% of the material in the drum.

This five minute video spotlights the advantages of using variable-speed drives (VSDs) to control motor speed on pumps and fans. Relax to a little jazz accompanying the automated PowerPoint presentation explaining the resulting energy-cost savings, reliability improvements, and reduced maintenance. Included is a detailed analysis of the Affinity Law relating pump flow and head to shaft speed.

Follow the guidelines offered in this Modern Pumping Today article to protect your liquid pumps from the damage done by dry-running conditions. Also addressed: flow disturbances such as elbows and valves installed too closely to the pump. The article explains when and where to use the various styles of point flow/level switches and elbow flow conditioners.

A Lubrication Management & Technology article offers numerous examples of pump installations where the addition of secondary oil filtration improves process-pump performance. Learn about a chemical plant that upgraded two pumps tasked with moving abrasive products; and an auto plant leveraging secondary filtration to annually return more than $1 million to its bottom line.

Wisconsin's Crystal River Lift Station is the subject of a recent Water & Wastes Digest case study. It's a tale of pumps clogging as often as 3x per day from "an array of crud," and the resulting unhealthy environment. To the rescue: pumps specifically designed to handle modern-day debris such as polymer-fiber wipes and disposable cleaning heads.
