Pentair Expands European Pump Presence with Acquisition of Jung Pumpen GmbH

Pentair (NYSE:PNR) today announced that it has reached a
definitive agreement to acquire the assets of Jung Pumpen ("Jung"), a
leading German manufacturer of wastewater products for the municipal
and residential markets. Jung brings to Pentair its strong application
engineering expertise, and a complementary product offering, including
a new line of water re-use products, submersible wastewater and
drainage pumps, wastewater disposal units and tanks. Jung also brings
to Pentair its well-known European presence, a state-of-the-art
training facility in Germany, and sales offices in Austria, France,
Hungary, Poland and Slovakia.

"Pentair Water expands its reach into the European wastewater
market with the addition of Jung," said Richard Cathcart, Pentair vice
chairman. "We view the wastewater market as an attractive growth
opportunity - especially in Eastern Europe, where environmental
considerations, new regulations and improving infrastructure are
accelerating the connection rates of homes to municipal
infrastructure."

Cathcart said that with Jung's strong distribution, sales and
service network, Pentair will be positioned to more effectively serve
the European market with both the Jung line and the Company's
Hydromatic(R) offering. Hydromatic is an industry-leading, diversified
line of submersible sump, sewage, effluent, and grinder pumps, large
non-clog pumps and self primers.

The transaction is subject to receipt of approval from the German
Federal Cartel Office and is expected to be completed in early 2007.
No additional terms were disclosed.
