Verderflex industrial peristaltic pumps are designed to be extremely robust and are therefore suitable for heavy-duty operations on intermittent- or continuous-duty cycles.

According to the company, they are a simple-to-use, easy-to-control, versatile and reliable way to pump liquids.

As a result, the pumps can be used for a diverse range of applications.

Application examples

Anaerobic digestion sludge transfer

Verderflex pumps were specified due to the high suction lift and the sludge’s solid content. The pumps transfer sludge to digestion tanks as part of a biofuel energy plant.

Thickener underflow slurry

Six VF125s pump 60–80 per cent solid content, 1.8 SG chrome and platinum slurry at the world’s largest platinum concentrator in South Africa.

Dosing and transfer of refuse leachate to incinerators

The Suzhou Waste Incineration Plant installed 12 Verderflex peristaltic pumps as part of the leachate process and injection system. The abrasive leachate is pumped from the collection reservoir through an automatic cleaning filter and collected in a draining reservoir.

Calcium hypochlorite dosing

Three Dura 25s with PP flanges replaced problem vapour locking diaphragm dosing pumps. Sterilisation of water supply is dependent on hypochlorite being dosed and this water is then supplied to one of Johannesburg‘s largest informal settlements.

Copperas crystal dosing

Copperas crystals (solid ferrous sulphate) are mixed at a power station to form a liquid that is re-circulated and dosed by Dura 15 pumps to form a protective iron coating on titanium condensation tubes.

Pumping kieselguhr

Several Dura 25 pumps dose and transfer kieselguhr or diatomaceous earth in a Bavarian brewery’s beer filtration process, filtering 1,200hl of beer every eight to 10 hours.

Water-based ink transfer

A change to water-based inks resulted in final product quality issues as the original AODD pumps experienced foaming problems for this printer. Dura 15 pumps are now fitted onto each print line, eliminating bubbles in the ink because of their gentle pumping action.

Filling UV ink bottles

A digital photo processing plant commissioned a factory profitability expert to eliminate manual UV ink bottle filling. The concept was proved using standalone Rapide R3Ss and R17Ss, leading to purpose-designed filling stations each using 4×2-channel R17S.

Filter press feed

An imbalance of low and high pressures can occur as a result of injecting the fluid for a chamber filter press system. With their extended range of accessories, Verderflex hose pumps ensure a trouble-free, controlled operation.

The dosage of polymers

The dosing of liquid polymers into sludge during the separation and dehydration process requires precise measurement at all stages of the treatment. Verderflex VF and Dura hose pumps can dose the fluids precisely at high pressure and without shear.

Activated carbon

The transfer of lime milk or activated carbon is an essential step in the treatment of wastewater and potable water. Maximum efficiency, reliability and reduced maintenance costs are ensured when using Verderflex pumps.

Verderflex® peristaltic hose pumps and tube pumps are the ideal solution for pumping liquids and dosing chemicals. Ranging from smaller Original Equipment Manufacture (OEM) pumps to the world’s largest hose pumps used in very heavy industrial applications.

Verderflex® peristaltic hose and tube pumps are used in many industries including: water and wastewater, mining, food & beverage, chemical, pharmaceutical, printing and packaging.

Verder’s peristaltic tube and hose pumps can pump abrasive, highly corrosive, viscous, high density and shear sensitive products.
