Process industries

A record of food and beverage success

We have a global network of industry specialist engineers providing support in the food and beverage industry. Our experienced team can keep your process running efficiently—improving uptime, increasing output, and removing production bottlenecks.

Maximum product quality, maximum uptime 

Peristaltic and sinusoidal pumps are among the fastest growing pump types in the food and beverage industry. 

Overcoming challenges

We develop pump and hose technologies that overcome the high viscosity, temperature and pressure challenges. 

Saving processing times and waste

With experience across processing, handling and effluent management, our products and services deliver significant savings in labour, processing times and waste that constitute tangible gains in sustainability and operating profit margins.

Choosing the right technology

We have revolutionised industrial pumping technologies and overcome fluid handling problems that cause other pump types to fail.

Our scalable pumps and flexible kink proof hoses are helping thousands of engineers improve the reliability, safety and efficiency of their process. This equates to costs savings that are critical to sustaining competitive products and services.

Reliable, low maintenance industrial fluid management

With no rotors to wear, or seals and glands to flush, peristaltic hose pumps handle abrasive fluids without the maintenance costs of other pumps.

Safe, accurate chemical dosing

Our technology helps to reduce chemical waste with a consistent, controllable flow.

Long-life PTFE hose technology for fluid flow applications

Unique steel braid and rubber coated hose technology delivers chemical resistant, low friction fluid handling through convolution free PTFE liners.

Intelligent chemical metering and transfer technologies

Peristaltic pumps that accurately pump abrasive chemicals such as lime slurry, powdered activated carbon (PAC), sodium hypochlorite (hypo), alum and other chemicals.

Chemical metering and transfer requirements

Watson-Marlow's tube pumps and hose pumps handle a broad range of chemical metering and transfers that destroy progressive cavity, lobe and diaphragm pumps.

Abrasive chemicals such as lime slurry, powdered activated carbon (PAC), sodium hypochlorite (hypo), alum and other chemicals wear metallic parts and rip through rotors, stators and seals of other pump types causing a maintenance nightmare.

Our positive displacement pumps provide consistent and reliable performance. The features include:

• High pressure capability for chemical injection
• Metering accuracies to +/- 0.5% saving on expensive chemical usage
• No ancillary equipment required
• Only one wearing part – the tube/hose
• Self-priming, dry running, no vapor locking
• Lower total cost of ownership

With peristaltic pumps the slurry is securely contained within the hose, only contacting the hose making maintenance simple.

To meet these tough demands, our wide range of long-life peristaltic pumps and hoses are designed to make mining and quarrying processes more efficient, profitable, and sustainable.  From metallic oxide to sulphide and carbon-based ore extraction, our pumps are specifically engineered for tough mining operations in harsh environments.

Unlike other types of pumps, our peristaltic pumps deliver exceptional results in handling viscous fluids and overcoming the challenges of abrasive, high-solid paste, and aggressive chemicals.

Less water consumption

Clog-free, robust and reliable Bredel hose pumps can handle undiluted tailings and thickener underflow with up to 80% solids. As Bredel hose pumps do not have seals, they eliminate the need for water flushing, so reduce the treatment of process wastewater and the need for pump service water.

Solutions to minimise impact on the environment

Reducing water usage also results in lower chemical usage and less energy required for treating process wastewater.

Qdos chemical metering and dosing pumps provide accurate, repeatable and contained reagent dosing, pH control and slurry transfer between flotation stages and milling stages.

PTFE hoses developed for automotive engineering

Our expertise in hose engineering helps you meet the need for increased levels of durability and flexibility in automotive design. Our PTFE-lined hoses are chemically resistant and capable of handling high-temperature fluids, helping automotive professionals overcome their engineering challenges. 

Unlike rubber, Aflex stainless steel braided PTFE-hoses exhibit minimal volumetric expansion under pressure. When the brakes are applied, the callipers move immediately, without delay needed to expand a rubber hose. Highly flexible and kink resistant, with a low force to bend, our hose technologies enable engineers to try new layouts and hose configurations.

Helping engineers to innovate

Innovation has been at the forefront of automotive success over the past four decades. Whether you are seeking weight reduction, increased flexibility or kink resistance, Aflex have developed patented liners and unique processing techniques to meet your application requirements.
