Oct 24 (Reuters) - Diversified manufacturer Dover Corp ( DOV )

cut its annual profit and revenue forecast on Thursday,

hurt by headwinds in polymer processing and beverage can-making.

Shares of the company fell 2.7% in premarket trading.

The Grove, Illinois-based company produces consumable

supplies, aftermarket parts, software and digital solutions to

serve a variety of industries, and has flagged persistent snags

related to polymer processing and heat exchangers as drags on

performance.

Dover's pumps and process unit, which contributes over 20%

to overall revenue, makes engineered precision components for

several industries and is heavily reliant on polymer production.

The company has also been involved in a bigger push to

streamline its portfolio and focus on higher-margin operations.

In July, Dover also said that it was entering an 18-month

period of buying opportunity for assets including "many private

equity-owned businesses that are overdue for exits."

Dover now expects its annual profit per share to be between

$10.11 and $10.21, compared to its prior range of $10.80 to

$10.95. The company sees revenue in the year growing between 1%

and 3%, compared to its prior expectation of between 3% and 4%.

The company's net income in the quarter ended Sept. 30 rose

to $313 million, or $2.26 per share, compared with $262 million,

or $1.86 per share a year ago.

Dover reported a 1% rise in quarterly revenue to about $1.98

billion from a year ago.
