Visitors will view the internal components of the pump head, including the triplex diaphragms of the fully-functional pumps with their clear perspex head and other cutaway demonstration pumps on display.
The MT08 exceeds API 675 standards and boasts extremely low pulse flow with multiple diaphragms in a single pump head. These negate the need for pulsation dampeners delivering accurate and smooth flow for chemical dosing and metering applications.
The MT08 is part of Wanner’s Hydra-Cell seal-less range of low pulse dosing solutions. These have earned a solid reputation for reliability, with pumps still operating 25+ years after installation. They also require very low planned maintenance and servicing requirements leading to a reduction in operating costs.
It is the true positive displacement pumping action and the low pulsation which makes the pumps so highly energy efficient, with more than 90% energy conversion from pump shaft input power to hydraulic output power possible, achieving significant savings.
There are no leaks of the process liquid as the pumping chamber is 100% sealed and no liquid waste. Many traditional pumps (centrifugal, gear, lobe, progressing cavity) used in sub 5m3/hr liquid transfer duties have dynamic seals. Often the process liquid is affected by air or moisture forming micron size suspended solids.
These suspended solids damage seals and packing resulting in unplanned maintenance. Dynamic seals need the process liquid to lubricate them. Pumping non lubricating thin liquids such as alcohols can be challenging for these pumps. The Hydra-Cell pumps seal-free packing-free design eliminates these issues.
This is especially important when handling difficult-to-pump or corrosive liquids. For some applications oxygen cannot be allowed to enter the process, including those that are susceptible to crystallisation such as sodium hydroxide or various acids.
Crystals in pumps can cause the pump to breakdown, leading to unplanned downtime, regular seal-flushing and increasing lifetime costs. Hydra-Cell’s unique, spring loaded vertically orientated check valves allow particles to flush through giving more reliable performance when pumping liquids with solid suspensions.
HPLC and “Flow Chemistry” applications for continuous production of pharmaceutical and fine chemicals can mean pumping expensive liquids. The elimination of pulsation dampers eliminates the waste of expensive chemicals. The compact design of the Hydra-Cell pump in these often high pressure applications reduces pump footprint and processing skid size and weight.
Filtration processes such as, ultrafiltration, nanofiltration, reverse osmosis and ultra-high pressure filtration often challenge the chosen pump technology by having to process difficult liquids (non-lubricating, corrosive, abrasive).
With a wide choice of material selections combined with the Hydra-Cell pumps unique features handling these types of liquid in these processes can be done reliably and with an optimal life cycle cost.
In spray drying operations the process pump must reliably handle supersaturated liquids and liquids with suspended micron solids. Hydra-Cell pumps have earned the reputation globally in many industries as the “goto” technology including chemical (dye production), agro-chemical, food etc and all kinds of powder manufacturing.
Its combination of seal-less design, true positive displacement pumping action and unique valve design all work together to result in a low cost of ownership for these types of applications.
In algae processing for biofuels, a low shear pumping action is essential to maintain the algae properties. Through extensive testing by a major player in this market it has been shown that the Hydra-Cell pumping action is suitable for low shear applications.
Also in full operation at the show will be the Hydra-Cell G10 with Intelligent Pump Control™. This comes into its own in applications where a fixed pressure and variable flow rates are required, such as hydraulic presses or lance cleaning, say, in the food industry. This also delivers high energy efficiency.
Hydra-Cell pumps are very simple to service, with no special tools required for inspection of diaphragms or check valve assemblies. They have no packing, can run dry indefinitely and are self-priming.
Paul Davis, Managing Director of Wanner International, said: “We are really pleased to be returning to ACHEMA after such a long break due to the pandemic. And we are particularly pleased to be able to demonstrate our innovative pumps for the industry to see their safety, accuracy, flexibility and efficiency for themselves.”
Wanner’s pumps are a must have for any industry looking to reduce its carbon footprint and increase sustainability. The company is dedicated to playing its part in addressing the climate change crisis, whether that’s reducing energy consumption, minimising waste or manufacturing products which are built to last.
Wanner’s culture embraces change and it has designed and developed pumps to help customers in their new processes and using different and difficult liquids. The company has responded to a number of drivers for change from the process industries and society more widely, bringing to market safe, reliable, accurate and flexible chemical processing and dosing application solutions.
Much of this change derives from sustainability and conserving the environment, which forces technology change in equipment design and different use of materials and processes. Hydra-Cell seal-less, packing-free pumps are perfectly suited to handle many difficult liquids at varying pressures and temperatures, and with operator safety and environmental responsibility as a priority for design.
Wanner International will be exhibiting on stand G37 in Hall 8.
