We won't go into a big explanation here, download the technical bulletin for all of the details. Suffice it to say that our pump valves are highly reliable and require minimum maintenance because there are only 3 parts - and only one of those move (hint: it's the one in the middle).

There are a lot of applications for this valve: slush pumping, chemical injection, water flooding, boiler feed service. We just know you're gonna like these pump valves!

These things have been around for years...more than a 100 of 'em! They've withstood the test of time because they just plain work. Our exclusive fabric coatings improve sealing efficiency, increase resistance to abrasion and extend service life.

Our Series 100 Pumcups are make of a cotton composition.
The Series 200 Pumcups are made of a polyester composition.
We still even make the Leather Pumcups.
