Discharge Port Connection (ESP-3500 only)
Figure 13: Discharge Tubing Connection
THIS OPERATION NEEDS TO BE COMPLETED IN ITS ENTIRETY BEFORE THE
MLE IS CONNECTED TO THE MOTOR.
1. Pre-fill the discharge tubing with dielectric oil by using a hydraulic hand pump to pump oil
into the tubing until there is a steady flow coming out the opposite end.
2. Cap off the ends of the discharge tubing to ensure oil remains inside.
3. Remove the fitting and ensure that the NPT threads have been Teflon taped.
4. Install the NPT fitting back into the base.
5. Remove the compression nut and ferrules from the fitting and capped off discharge
tubing.
6. Install compression nut and ferrules onto the capillary tubing ensuring the correct
ferrule orientation.
7. Place the capillary tubing with nut and ferrule into the fitting and hand tighten nut then
using a 9/16” wrench tighten the nut 1-1/4 more turns.
8. Remove the NPT plug directly above the NPT fitting.
9. Remove the capped off end of discharge tubing and reconnect to hydraulic hand pump.
10. Pump oil through the discharge tubing until a steady stream of oil without bubbles is
flowing through discharge pressure bleed port.
11. Reapply Teflon Tape to NPT plug and reinstall the NPT plug back into the pressure
bleed port.
12. Band the discharge line~6in above the pressure bleed port and then every 3ft to the top
of the ESP.
13. Nipple up the discharge sub.
14. Cut the discharge line to appropriate length and install into the velocity fuse fitting.
15. Tighten velocity fuse using a 9/16” wrench tighten the nut 1-1/4 more turns after hand
tight.
