IQ-Whipps 920 Stainless Steel Penstocks

The IQ-Whipps 920 is the standard offering in the range. It has a rugged, reinforced stainless steel construction which is combined with tough, flexible, ultra-high molecular weight polyethylene (UHMWPE) seat/seals. This provides a heavy-duty assembly and a flush bottom closure is provided by a resilient bottom seal. The seal is regulation 31 approved.

In addition to the wide range of standard penstock sizes, IQ Engineers can quickly and economically produce penstocks customized for unusual applications.

IQ-Whipps 920 Penstocks are manufactured under a licence from Whipps inc. who are a market leading penstock manufacturer in the USA. We work closely with Whipps who have been established since 1977 and supply penstocks throughout the USA.
