Pump monitoring with Atex certification

Monday, April 23rd, 2018 von admin

At this year’s Achema, Allweiler will exhibit its intelligent condition and operation monitoring system (hall 8.0, booth D63). Known as IN-1000, it is now also available with Atex certification for use in EX zones. IN-1000 was developed specifically for Allweiler pumps that are used in operationally-critical and environmentally-sensitive applications in chemical engineering.

The IN-1000 can be used for a wide range of condition monitoring applications, from simple, single-pump installations to complex, multi-pump systems while improving safety and reducing operating costs simultaneously.

New plunger pump head reaches up to more than 1,000 bar

Friday, April 13th, 2018 von admin

The plunger pumps feature an integrated gear, which enables very compact construction with maximum efficiency.

For the purpose of upgrading a cracker in a Chinese refinery a total of five plunger pump skids should be brought into operation by Lewa. Those in charge of the project opted for three triplex and two quintuplex plunger pumps in accordance with the API 674 standard. These pumps are equipped with the new KMC-L pump head with reduced clearance volume. This head consists of a single forging: The suction manifold is integrated as a result, allowing for a reduction in the sealing surface and thus in any potential leak points. An additional advantage is the fact that the suction side can be designed to handle backpressure, eliminating the need for a safety valve in the suction line. The new design makes it possible to realize pressures up to 1,075 bar. All pumps in use have been produced in Germany and mounted to a complete system in the Chinese plant.

These plunger pumps have a drive output of 260 kW and a flow rate of 25 m3/h. The suction pressure loss of the pump heads is very low, therefore a low suction pressure is needed and it is often possible to operate without a booster pump.

Pumps for wet flue gas desulfurization

Tuesday, April 10th, 2018 von admin

A cement factory in Texas was among the first in the USA  to install wet flue gas scrubbers in order to reduce the sulfur dioxide emissions. This is a demanding application for pumps because the gypsum slurry that “scrubs” the gas is highly abrasive and corrosive.

Special pumps with housings and impellers made of mineral cast prove to be a perfect solution here.

Wet Flue Gas Desulfurization Scrubber systems are a vital component in various industries due to strict environmental regulations. First applications were coal fired power plants and waste incineration plants. Today, other industries utilize wet scrubbers in their day to day operations as well to scrub flue gas emissions from burners that utilize coal as a fuel source.

Up to 33,000 m³/h

Friday, March 23rd, 2018 von admin

In response to the worldwide increase in large waste water projects, KSB has extended its range of large dry-installed waste water pumps. The pump manufacturer has developed an extra 15 sizes to add to its Sewatec pump series.

The maximum flow rate of the largest version will be up to 33,000 m³/h with a drive rating exceeding one megawatt.

An example of these pump sets will be showcased at the pump manufacturer’s trade fair stand at this year’s Ifat in Munich.

Hygienic high-pressure pumps for dairies

Wednesday, March 21st, 2018 von admin

Gea presented its first high-pressure pump for membrane filtrations such as reverse osmosis and nanofiltration in dairies at Anuga FoodTec 2018. The Hilge Hygia H is designed for system pressures up to 64 bar with outstanding cleanability characteristics and a modular motor connection.

The new high-pressure pump is based on the Hygia premium range of hygienic pumps, which has been proven for decades and is suitable for a large number of viscous fluids and applications as a result of its high surface quality and adaptability. It is designed to pump fluids as well as homogeneous media containing air or gas and withstands a system pressure of 64 bar. “40 bar is standard in the dairy industry”, says Martin Zickler, product manager for hygienic pumps at Gea.

Twin screw pumps for food applications

Wednesday, March 21st, 2018 von admin

Hyghspin twin screw pumps have a compact design and many versatile and flexible uses. The design of these pumps do follow hygienic design criteria. Their block construction saves space and always ensures a correctly aligned coupling.

Mobile units including frequency converter and service switch are another feature of this pump range. These units stand out, among other things, on account of their self-priming qualities and ease of service. Safe-to-run dry seals, for example, require no flushing.

Crane offers technical paper “Sensible Heat Transfer”

Wednesday, March 21st, 2018 von admin
Originally published by Crane Co. in 1942 as The Flow of Fluids handbook, the TP 410 has grown to become a classic guide for plant engineers, technicians, maintenance personnel, plant operators, safety engineers, recent college graduates and sales representatives in the
selection of the correct equipment and parameters when designing and operating any piping system.
The 2018 edition marks the introduction of a new chapter titled, “Sensible Heat Transfer”. Other entries include enhanced information on Pumps, Control Valves and Flow Meters, as well as an updated bibliography and technical references. A suite of web based tools that solve equations found within the paper can be accessed online at www.TP410.com in real time.

Newly expanded range of pharmaceutical pumps

Monday, March 19th, 2018 von admin

Alfa Laval is expanding its range of UltraPure pharmaceutical pumps with even more selection. Whether a pharmaceutical or biotech process requires a centrifugal or PD (positive displacement) pump, the complete range of Alfa Laval UltraPure pumps cover virtually any pharma or biotech need. “These are safe and reliable pumps, with features such as hygienic design, repeatability and minimized contamination risk,” says Alfa Laval UltraPure Portfolio Manager John Walker. “Along with higher yields, increased uptime and the low energy consumption, this translates into lower user costs. As sustainability aspects continue to gain traction in the market, the pharma and biotech industry will appreciate the energy efficiency and low CO2 footprint.”

Pumping sparkling wine without foaming

Friday, March 16th, 2018 von admin

CO2 increases the tendency of the beverage to foam, which impairs the quality of the goods. An Italian winery has therefore been using a particularly low-pulsation, hygienically safe rotary lobe pump of German manufacturer Netzsch.

This T.Sano pump guarantees not only the desired pressure over the entire pumping distance – and thus the quality of the wine – but also reliably prevents the un-wanted development of foam. In this way, more precise dosing and better barrel emptying is achieved.
