TAPFLO, a leading supplier of air operated diaphragm pumps, centrifugal pumps and other industrial process equipment, has announced a new product range for a surface treatment industry. The company has launched a plastic version of its CT centrifugal pumps family - the CTP Pump.

The new pumps are available with BSP thread, flange or hose connections. They can be used for chemically corrosive and toxic liquids as well as for clean and thin liquids like pure chemicals, acids and alkalis because the wetted components are non-metallic, injection molded thermoplastics enabling excellent corrosion resistance.

”The version in PP-GF (glass fibre reinforced polypropylene) provides great mechanical strength and allows liquid temperatures up to 70°C. The PVDF (PolyVinylidine DiFluoride) version has superior chemical resistance and allows temperatures up to 80°C – 90°C,” said Mikolaj Laguna-Horodniczy from Tapflo Marketing.

Jakub Zduńczyk Product Engineer at Tapflo said the mechanical seal is located on the dry side of the pump and is protected against contact with the liquid. ”In addition, the spring is made of Hastelloy C which increases its chemical resistance in the unlikely event of a leakage.

”What characterizes our new plastic pump from is that the pump is equipped with a drainage option, which is designed to protect the motor against contact with any aggressive medium. CTP pumps allow pumping solid particles up to 3mm in size and 10% in concentration. What is more the pump can handle metallic particles.”

The new pumps can be used in various applications: transfer of various chemicals from storage tanks to smaller containers, transfer, filtering and circulation of surface treatment baths, pumping of CIP detergent used for cleaning of pipes and other food process equipment, dosing of acids and alkalis used as cleaning chemicals in Nano filtration, to name a few.
