Seven pump selection errors that stay invisible at quote time – from NPSH margins to viscosity correction. The free VSX whitepaper “Best Practices for Avoiding Hydraulic Pump Selection Errors” shows engineering and sales teams how to spot them early, what they cost and which standards apply. Includes an 8-point pre-selection checklist.
Double diaphragm pumps operate using an oscillating positive displacement principle. The pump consists of two main fluid housings and a central air control section. Inside each housing, a flexible diaphragm is mounted vertically and connected to a shared shaft. As compressed air enters and exits the air chambers, the diaphragms move in a coordinated push pull motion.
In a contributed article, Adrian van Wyk, Managing Director of Referro Systems, explains why purchase price, motor power and flow curves are losing weight in pump selection. He points to lifecycle cost, efficiency across the actual operating range and the limits of predictive maintenance without matching maintenance processes.
SIMFLO has appointed two Directors of Sales and four Regional Sales Managers. Greg Hebert and Andrew Grubbs now lead sales for the Engineered Products Group and the Standard Products Group, while Rodney Ball, Kelly Cowden, Billy Johnson and Kevin Schaal join the regional sales team.
ISH will take place in Frankfurt am Main from 15 to 19 March 2027. The organiser expects more than 2,000 exhibitors. The range is structured into nine solution fields, including “Water-bearing Systems”, “Heat Generation” and “Sanitary & HVAC Production”. New features include the “Drinking Water Compliance Forum” in Hall 4.1.
According to its first Sustainability Report, around 99% of DAB Group’s carbon footprint is associated with the use of its pumps after they have been sold. The report also shows that the manufacturer has reduced its Scope 1 and 2 emissions by 62% compared with 2020, exceeding its own 2030 target of 50% five years ahead of schedule.
The sixth Water Indonesia will take place in Jakarta from 15 to 18 September 2027. The trade fair focuses on water, wastewater and recycling technologies.
Siemens now also offers its Sitrans MS200 multisensor for hazardous areas. The intrinsically safe sensor is designed for wireless condition monitoring in Ex Zone 1 applications (ATEX/IECEx) and measures vibration, temperature and magnetic fields on pumps, motors, agitators and other rotating equipment.
Rain, mud and frost place high demands on construction site drainage in autumn and winter. Pump manufacturer Tsurumi outlines five typical mistakes – from an underestimated flow rate and unprotected pipes to maintenance carried out only after a breakdown – and explains how construction companies can avoid failures and costly site shutdowns.
Thordon Bearings has opened a third manufacturing facility in Burlington, Canada. Plant 3 will primarily produce TG100 water-lubricated mechanical seals and water quality packages for the marine and hydropower markets. The facility also houses the company’s New Product Development team.
Royal Purple Industrial, an affiliate of Lubrication Engineers, presents its NSF H1-registered synthetic lubricants for the food and beverage industry. The portfolio covers compressor oils, a barrier fluid for double mechanical seals and a multi-purpose lubricant for pumps, gearboxes, bearings, hydraulic systems and blowers.
HOMA has expanded its Alligator (OC) chopper pump range with additional hydraulic variants in the DN80 and DN100 connection sizes. Both sizes are now available with 2-pole or 4-pole motors and can be used in wet well or dry well installation. The range now covers a broader spectrum of heads and flow rates.
