Dickow Pump No cooling water needed for these hot-water pumps This company offers a wide range of hot-water pumps for temperatures up to 530°F and design pressures up to 1,160 psi. Due to high vapor pressures, standard mechanical seals cannot be used for higher temperatures. Although cooled mechanical seals are the easiest solution, the required cooling water adds additional costs. An alternative is a...

Designed for flow chemistry applications, the patented Asia Syringe Pump is said to give users a tool for performing flow reactions not possible using HPLC pumps or...
February 1, 2013
Determining the proper preliminary size for centrifugal pumps during the initial stages of any pump-specification exercise requires numerous calculations and assumptions. This article reviews the steps needed to size centrifugal pumps during the early stages of a project, to support initial cost-estimation efforts. Such early pump-sizing efforts are important steps toward final pump selection and detailed...

The portable, non-metallic Flex-I-Liner rotary peristaltic pump evacuates drums and totes containing acids, caustics, salts, chlorides and reagent-grade chemicals without corrosion of the pump or contamination of the fluid. The self-priming design of the Flex-I-Liner has no seals...
December 1, 2012
The new DEPA Nopped S Diaphragm features an innovative “nopped” surface, designed to create advantageous flow conditions emulating the effect of golf-ball dimples. The use of Santoprene as its core material — a substance...
November 1, 2012
The prices of low-voltage variable frequency drives (VFDs) have declined substantially since they were introduced, while the cost of power has increased. Normal project economics will now justify these VFDs — which go up to 375 kW (500 hp) or beyond — for pumps over the largest part of the range of application of the pumps. To efficiently evaluate and apply VFDs, process engineers need to know...
November 1, 2012
The Model G3 Progressing Cavity Pump is designed for handling material with high solids content, and those that are semi-dry or caked. The product features a series of finger mechanisms...
October 1, 2012
The new Pivotrol PTF4 is a high-capacity, pressure-powered condensate pump that covers a wider motive-pressure range. This new version can be operated by steam, air or other...
September 1, 2012
The Compact Vertical Dosing (CVD) system features a modular design that makes it possible to add or replace fittings and components during, or even after commissioning and without cost-intensive modifications. The...
September 1, 2012
The new E-Series Plastic AODD (air-operated double diaphragm) pumps feature no mechanical seals or packing, thereby eliminating a critical leak point. Instead, these pumps have a stainless-steel containment ring...
September 1, 2012
Pumps are among the most commonly used machines in the chemical process industries (CPI). Condition monitoring tests and predictive maintenance can help pump operators determine when to overhaul pumps in a way that minimizes costs. Despite pumps’ ubiquity and large energy demands, however, relatively little information is available on how to apply predictive maintenance approaches and condition...
