Be Safe. Be Clean. With SANDPIPER’S Innovative Signature Series Pumps

Published

on

 

 

The SANDPIPER Signature Series of AODD pumps are engineered to provide industry leading durability and performance—even in the most severe applications and environments.

 

Not all pumps are created equally. The SANDPIPER Signature Series, offered by Warren Rupp, Inc., is in keeping with the company’s commitment of the past 50 years to build “new and different” pumps. These innovative, air-operated double diaphragm (AODD) pumps come in a variety of sizes, types, and models to meet a wide array of industrial applications. The series includes:

  • Heavy Duty Flap Valve Pumps 
  • Heavy Duty Ball Valve Pumps
  • Containment Duty Ball Valve Pumps

This article focuses specifically on the Containment Duty type pumps, which enable safe movement of harsh materials for heavy industrial applications that involve chemical, abrasive, slurry, solid-laden, caustic, acidic, toxic, and combustible product.

Fluid containment

We live in a time of growing environmental and safety concerns, strict regulatory controls, as well as cost consciousness. Industrial pumps, in particular, represent potential hazards with respect to dangerous leaks that can cause harm and unnecessary expense. Whether pumping toxic or non-toxic fluids, the goal is to prevent any escape into the environment. Not only does such an incident require significant clean-up time and effort, it also incurs costs of downtime, lost production, manpower, equipment replacement, disposal fees, and often excessive fines.

 

The rugged construction of Warren Rupp’s Containment Duty Ball Valve Pumps provides superior fluid flow with specially designed containment features to protect people, the environment, and the pump, itself. Based on the premise that two diaphragms are better than one, this pump is built with an intentional space between its dual diaphragms (a pumping diaphragm and a driver diaphragm), creating a barrier between the Air Side and Wet Side of the pump. Thus, fluid is prevented from escaping to the environment should the pumping diaphragm become breached. It also provides visual leak detection alerts to inform users when there is a diaphragm breach before any of the system fluid can escape (also available with electronic and mechanical leak detectors).

 

The biggest benefit of the Containment Duty pump over traditional AODD pumps is the ease of repair, since the Air Side of the pump does not get contaminated. And the design allows quick and easy access to the main air valve components—without removing it from service. The result is minimal maintenance cost and downtime.

 

Additional pumping options

The other types of SANDPIPER Signature Series pumps also provide powerful AODD capabilities that outperform the competition, as follows:

  • Heavy Duty Flap Valve Pump —  designed to handle fluids containing large, up-to-line size solids (for example: rocks, twigs, leaves; nuts, bolts screws; and rags)
  • Heavy Duty Ball Valve Pump — designed to handle fluids containing settling, suspended or floating solids, and abrasives (for example: sand, slurries, pea gravel, etc.)

Delicate and quiet operation with Alfa Laval’s new robust Twin Screw Pump

Published

on

Designed for handling fluids which are sensitive, abrasive, and either high or low viscosity, the Alfa Laval Twin Screw Pump is ideal for use in hygienic applications in the dairy, food and beverage, and personal care industries.

“The Twin Screw Pump is the ideal choice for both high and low viscosity liquids, all pumped perfectly with complete reliability,” says John Walker, Pump Portfolio Manager.

 Additional benefits of the Alfa Laval Twin Screw Pump are that it is quiet and virtually pulse-free, as well as being smooth and gentle during operation. These characteristics make the pump an excellent choice for handling sensitive products.

 Built on a robust, reliable platform that meets stringent hygienic standards, the pump is capable of handling both product transfer and Cleaning-in-Place (CIP). Its low pulsation characteristics and excellent solids handling capabilities reduce the risk of product damage, thereby improving product quality. Maintenance is simplified and process uptime increased.

 Process flexibility

Two-in-one operation provides easy handling of process media of varying viscosities as well as CIP fluids. This simplifies piping and pump control, cutting costs and minimizing contamination risks. Superior suction performance with excellent lift capability and low NPSHR provides installation flexibility and increases product recovery.

Service and reliability

Quick, easy seal replacement with the pump in place is made possible, thanks to a cartridge seal with a truly front-loading, self-setting design. This maximizes process uptime and minimizes maintenance costs. An optional seal service kit program adds maintenance flexibility and cuts operating costs.

Operational safety

The Alfa Laval Twin Screw Pump features a clean, external stainless steel finish with profiled elastomers and mechanical seals fully surrounded by the product. Designed for maximum cleanability using FDA-conforming materials, the pump is both EHEDG- and 3-A certified. An optional ATEX version enables use in hazardous zones.

Alfa Laval is a leading global provider of specialized products and engineering solutions based on its key technologies of heat transfer, separation and fluid handling.

The company’s equipment, systems and services are dedicated to assisting customers in optimizing the performance of their processes. The solutions help them to heat, cool, separate and transport products in industries that produce food and beverages, chemicals and petrochemicals, pharmaceuticals, starch, sugar and ethanol.

Alfa Laval’s products are also used in power plants, aboard ships, oil and gas exploration, in the mechanical engineering industry, in the mining industry and for wastewater treatment, as well as for comfort climate and refrigeration applications.

Pumps bring comforts to travelling Pandas

Published

on

The two pandas arriving from China to Copenhagen ZOO will settle into the brand-new Panda House powered by Grundfos among others.

A technologically advanced home is waiting for the two pandas that have arrived to Copenhagen ZOO as an official gesture from China to HM Queen Margrethe of Denmark.

The 4000 square meter Panda House is designed by architect company BIG and financed by a range of Danish companies and foundations, including Grundfos.

We have supplied 15 MAGNA3 circulation pumps and one PUST pumping station to regulate heating, cooling and water, which includes a stream running through the complex.

Installation work has been carried out in cooperation with installer company C5 VVS & Ventilation A/S. For Grundfos, the project was a chance to ensure comfortable surroundings for the furry travelers in a setting, which emulates the animals’ natural surroundings.

“I am not sure we have ever delivered solutions for pandas, but together with ZOO, designers and installers, we have worked hard to ensure they will enjoy their new home. I feel privileged that we were able to back this project and contribute our knowledge and products to such a fantastic complex, designed with a great focus on animal welfare,” says Brian Sørensen, Sales Director, Grundfos.

Historic event

At Copenhagen ZOO, preparations have been underway for almost 10 years. Expectations are high ahead of the grand opening of Panda House.

“Thanks to contributions from 16 large Danish companies, we have built a facility that will raise Denmark’s profile internationally for many years to come. We have had animal caretakers, zoologists and veterinarians on education in China and been in close dialogue with Chinese professionals since 2010. And we have not least a whole plantation on South Zealand with sprawling fresh bamboo. So I dare say: we are ready to accept our newest residents, because this is, in the original sense of the word, a historic event,” says Jørgen Nielsen, CEO of Copenhagen ZOO.

Symbol of friendship

Pandas are a national treasure in China, and Denmark is only the 19th country ever to receive pandas. The gesture is a symbol of friendship and trust that rings true for overall Sino-Danish relations and the special bond between Grundfos and China.

“It is very rare that pandas are sent to other countries, so this is indeed a humbling and great honor, which illustrates the excellent friendship between Denmark and China. Our involvement in this project makes perfect sense, as we have forged strong links with China over the years,” says Brian Sørensen.

MAGNA3 gets environmental certificate

Published

on

In an industry first, our circulator pump now comes with an Environmental Product Declaration, documenting the product’s impact on the environment.

The footprints left by MAGNA3, in terms of energy consumption, chemical substances and emissions, have been detailed in an Environmental Product Declaration (EPD). It is the first time any pump manufacturer acquires an EPD in accordance with the European standard EN 15804.

“It is a very important step for Grundfos to be able to document towards our customers the environmental performance of our products in a standardised way,” says Mathias Høeg, Senior Life Cycle Assessment Specialist at Grundfos.

Widely requested

The third-party verified document, issued by independent assessors at the German Institut Bauen und Umwelt, communicates transparent, comparable information about the product’s life-cycle impact.

Having an EPD does not necessarily imply that the declared product is environmentally superior to alternatives. It simply provides facts, which are widely requested among Grundfos customers and partners.

“This area is becoming a hot topic here. As an example, with a strong focus on Nearly Zero Energy Buildings, the architect on an upcoming housing development project requires an EPD for the pumps,” says Mark O’ Sullivan, Sales Engineer at Grundfos Ireland in a sentiment echoed in various markets around the world.

 More products in sight

The next step will be to obtain the EPD for even more products, which falls in line with Grundfos’ ongoing ambitions to deliver as energy-efficient and environmentally friendly products as possible and to do so in a transparent manner.

“Working with EPDs and life cycle assessment influence the way we develop new products. Environmental performance will be considered alongside other design criteria such as price and functionality. This is possible because environment as a term can now be measured and communicated in numbers and graphs,” explains Mathias Høeg.
