Frequently Asked Questions
What makes the WTFP Series suitable for thermic fluid applications?
The WTFP Series is specifically engineered for thermic fluid and hot oil service, with temperature capability up to 350°C, high-temperature mechanical seal options, and materials such as CS, SS-316, and Alloy 20 that retain structural integrity under sustained thermal cycling.
What is the maximum head the WTFP Series can deliver?
The WTFP Series delivers up to 150 metres of head — the highest in Wel-Tech's centrifugal process pump portfolio — making it suitable for demanding high-pressure thermal circuit designs and elevated delivery points.
Can the WTFP pump handle aggressive chemical fluids at high temperatures?
Yes. The availability of Alloy 20 and SS-316 material options ensures compatibility with a broad range of chemically aggressive fluids at elevated temperatures, covering petro-chemical and chemical process applications.
Is a performance test certificate available with every pump?
Absolutely. Every WTFP Series pump is tested in our in-house performance test facility. Full material certification and hydraulic performance certificates are available at a moment's notice. Customers are also welcome to arrange a visit to our Ahmedabad production facility for on-site testing.
