The Stayflow BST Series basket strainers offer a durable and compact solution for corrosive or sanitary liquid applications, where space constraints require threaded connections. Constructed entirely from 304 stainless steel (with 316 optional), these strainers are ideal for food and beverage, chemical, pharmaceutical, and other high-purity or aggressive environments.
Each unit features a bolted cover and a removable stainless steel basket, with a standard 1/16" perforation and options for 1/32", 1/8", or mesh screens. Rated for 400psi at 100°F, the BST Series handles higher pressures while providing ease of cleaning through its integrated drain port and plug.
For a carbon steel version, see the BCT Series.
