QUALITY SOLUTIONS FOR PUMPING IN THE WATER AND WASTEWATER INDUSTRY

Wastewater treatment plants collect and treat wastewater from municipalities and industry. In this arduous environment there are many applications for pumping equipment that can handle the tough challenges.

Peristaltic pumps are proven performers in water and wastewater treatment - commonly utilised for the following applications:

• dosing and metering treatment corrosive or shear sensitive chemicals and reagents including ferric chloride, sodium hypochlorite, chlorine water, lime, caustic soda, powder activated carbon and polymers
• sludge transfer
• filter press feed

Their ability to dose accurately and the resistance to harsh and corrosive chemicals makes peristaltic hose pumps a versatile and reliable pumping option. Due to their unique design, hose and tube pumps can not only handle tough chemicals but pump thick sludges and solids in suspension with ease.

In water and wastewater treatment plants there are many difficult pumping challenges to be addressed to ensure trouble-free operation.

• as lime slurry is abrasive and often very thick, it can cause diaphragm pumps to clog and progressive cavity pumps to suffer from abrasive wear
• hypo can vaporise when pumped, causing diaphragm dosing pumps to vapour lock resulting in untreated liquid streams
• polymers are often shear sensitive and incorrect handling can destroy the fragile polymer chains leading to increased chemical usage
• the high grit content in primary sludge causes abrasive wear on rotary pumps

The wide range of Verderflex peristaltic hose and tube pumps are suitable for the type of pumping required for the harsh nature of the wastewater industry. Their gentle pumping action and lack of valves, seals and glands makes them inexpensive to maintain. Verderflex hose pumps are also known for their:

• seal-less design: peristaltic pumps have no seals, avoiding issues such as leaks of corrosive chemicals and ongoing maintenance
• dry running and self-priming: hose pumps can run dry without costly downtime or repairs. The inherent shape recovery of the hose or tube creates a self-priming action and allows the pumps to move liquids containing entrained air.
• gentle pumping action: the gentle, low shear pump action is ideal for shear sensitive products including flocculants and soft solids in food products
• corrosion resistant: apart from the stainless or PVDF inlet and outlet inserts, the pumped product only comes into contacts the hose, which is available in chemical resistant construction
• high suction lift: hose pumps have impressive suction lift capabilities up to 9.5m of water.
• solids handling: Verderflex hose pumps can pump slurries containing up to 80% inorganic solids or 15% organic sludge, including large soft solids in suspension
• pumps are reversible for two-way pumping or emptying pipelines of chemicals

The hose is the most important part of the peristaltic pump - and the range of hoses and tubes from Verderflex are designed to be the longest lasting in the market. Available in four different materials and reinforced with multiple layers, these hoses offer a tough solution for those harsh, corrosive and abrasive chemicals.

The wastewater industry depends on quality, tough and durable equipment. Whether it be dosing or sludge transfer, only the best pumping solutions will last.
