The Eddington QCBM & QCFM Injection Quills offer MNPT process connections and 1/2" FNPT pump side connections. Quills made from Type 316 Stainless Steel, Alloy 20, Hastelloy C276 can be used for high temperature, high pressure applications.
Test all of quills for a crack pressure of 10 psi. If the pump cannot deliver 10 psi then a QBFM injection quill may be appropriate.
Quills are available in Type 316 Stainless Steel, PVC, Kynar, Alloy 20 and Hastelloy C276.
The QCBM has no check valve and the QCFM Injection Quills have built-in ball check valves to prevent backflow through the nozzle and into the chemical feed line.
There are two flat surfaces on the external portion of the nozzle so a wrench can be used during installation.
Install Injection Quill with V notch facing into the flow for the most rapid dispersal of injected chemicals into the stream (see diagram above).
Standard Injection Quill length is 2 3/4" but custom lengths up to 24" are available.
