EAST PROVIDENCE, R.I.—New diaphraghms from The Bosworth Co. will last all season.

Bosworth, famous for their Guzzler line of pumps, has developed and will be mass producing new diaphragms made from a rubber material that will hold up and maintain through an entire sugaring season.

On a single diaphragm.

The new Made-in-USA diaphragms are made from an FDA-approved food-grade material called Santoprene.

“This will last through a whole season,” said CEO Doug Reilly.

In fact, in the company’s “test shed” in the back of their factory, Reilly and his production team have been running a Guzzler pump on one single Santoprene diaphragm continuously since December of 2022.

“It’s still going,” Reilly said, during a tour for The Maple News in August.

He still recommends that the sugarmaker still make an effort to keep ice out of the pumps, primarily by using a screen.

"When diaphragms fail it is because they stretch," he said.

He said the new Santoprene diaphragms will retail in the $60 range.
