Injection Valve Installation Diagram - CTX BIOCLEAN CONTROL Serie Manual De Instrucciones

Whenever the pump is dismantled from the process plant, you will be well advised to replace the caps on
the connectors to avoid residual liquid being spilled. Before attaching the delivery hose to the plant, prime
the metering pump by going through the sequence shown in Fig. 5. In case of priming difficulties, use a nor-
mal syringe to suck liquid from the discharge nipple while the pump is in operation, continuing until you
actually see the liquid rise in the syringe. Use a short length of suction hose to connect the syringe to the
discharge nipple.
f. - Try to keep both the suction and discharge hose as straight as possible, avoiding all unnecessary bends.
g. - Select the most appropriate injection point on a pipe of the plant to be treated and there fit a 3/8" female steel
gas thread connector (similar to BSPm). This connector is not supplied with the pump. Screw the injection
valve to the gas connector, inserting a gasket as shown in Fig. 6. Then connect the discharge hose to the
conical connector on the injection valve and fix it with the supplied tube nut G. The injection valve also acts
as no return valve by means of a cilinder sleeve (elastomer, standard supplied in Viton).
