Primary Shut-Oﬀ Trap, 3"
The Masport Primary Shut-Oﬀ Trap is designed to be the primary shut-oﬀ trap on liquid and semi-solid handling systems. The primary shut-oﬀ trap provides initial vacuum pump protection against contamination and damage from material carry-over. An independent shutoﬀ ﬂ oat cage assembly makes inspection convenient and fast. Chemical and corrosion resistant viton ﬂ oat seat and stainless steel ﬂ oat ball provide for superior durability. The non-restrictive, full ﬂ ow shut-oﬀ trap is sized to prevent early ﬂ oat ball activation. Our three sizes will match any vacuum pump with an airﬂ ow of 20 to 400 C.F.M.
