Evaluating Farm Slurry Extends Life & Performance [Pumps]

Pumps & Systems, Sept. 2014, by Paul Davies.
http://www.pump-zone.com/pumps/september-2014-evaluating-farm-slurry-extends-life-performance-0

"Pump manufacturers know that the engineering phrase “fit and forget” never holds true for rotating equipment. For all its reliability and longevity, a slurry pump that has been operating in a pit for several years will eventually fail. Several pumps can handle farming applications at a tenth of the initial cost for an application-specific slurry pump. However, replacing a cheaper, less effective pump every six months becomes a tiresome—and expensive—hassle for many farmers. This article features several examples of how selecting the right pump ensured worry-free operation in harsh pit service."

Pre-Screening Unlocks Savings Potential in Large Pump Systems

Pumps & Systems, Sep. 2014, by Ray Hardee.

"When facilities—whether paper mills, refineries, or chemical or waste treatment plants—decide to implement pump system improvements, the first question is always the same: Where to begin? This month’s column looks at the pre-screening process, when plant management teams decide which system to tackle first. The pre-screening process quickly identifies which pump system has a high probability of improving plant operations, reducing total cost and increasing system uptime."

Discusses the "the impact of relative dynamic-pressure losses and other factors on overall power demand and energy savings."

Eccentric Disc Pumps Create Product Recovery Cost Savings

Pumps & Systems, Jun. 2014, by Wallace Wittkoff.

"Targeted product recovery in hygienic manufacturing reduces waste, decreases operating costs and maximizes the use of raw materials and end products."

Progressive Cavity Pumps Provide Optimized Operation in Multiple Pulp & Paper Processes

Pumps & Systems, May 2014, by Nimish Sheth.

"Progressive cavity (PC) pumps are energy efficient and experience long life in harsh applications. Self-priming and with a low net positive suction head required, their positive displacement flow is proportionate to the speed and independent of discharge pressure. With their large capacity, PC pumps reach flow rates up to 1,500 gallons per minute and have high-pressure capability. With friction losses, pressures as high as 2,000 psi can be achieved. The addition of a cardan joint helps resolve wear and failure and delivers improved angularity and smooth transmission of radial and axial loads."
