Packing Adjustment On H4, H5, H6 Zone Pump
4.2.3 – PACKING GLAND LUBRICATION
The pump gland should drip approximately 1 drop per minute at 150°F (66°C) operating
temperature.
EXERCISE EXTREME CAUTION WHILE WORKING ON OR IN THE AREA OF
THE MOKON TEMPERATURE CONTROL SYSTEM. THE HIGH
TEMPERATURE OF THE FLUID WILL CAUSE THE PROCESS LINES, SYSTEM
COMPONENTS, AND METAL CABINETRY TO BECOME VERY HOT AND
THEREFORE THEY SHOULD NOT BE TOUCHED.
To check/correct the packing gland lubrication:
1. Remove the front and back panels from the system (system should not be on at this
point).
2. Remove the splashguard from the pump gland area.
3. Start pump by pressing the start button.
4. Set temperature controller to 150°F (66°C). (See section 5 for controller instructions)
5. Observe the oil dripping from the packing gland. If it is not dripping at the recommended
1 drip per minute, adjustment is needed.
NOTE: If installing new packing rings it will be necessary to allow the system to run
for a period of time before checking the dripping rate of the oil.
6. The pumps adjustment collar mechanism consists of two capscrews (11), one on each
side. They may be tightened to decrease the dripping or loosened to increase the dripping.
See figure 1.
NOTE: The adjustment collar capscrews must be EVENLY tightened or loosened,
one flat at a time, to achieve proper adjustment. Failure to do so will result in
damage to the pump. Overtightening will destroy the packing.
4.2.4 – REPLACING PUMP PACKING
To replace the pump packing:
1. Loosen the adjustment collar capscrews (11).
2. Remove the adjustment collar (9).
3. Using a packing hook, remove the packing rings (12).
4. Install new packing rings (12), staggering the joints left to right. Lubricate the packing
rings with oil, grease, or graphite to aid assembly. A length of pipe will help seat each
packing ring. Install the same quantity of rings removed. (Typically, 6-7 rings)
5. Replace the adjustment collar (9). Make sure that it is installed squarely.
6. Reinstall the capscrews (11). Tighten wrench tight then back off until gland is slightly
loose.
NOTE: The capscrews must be tightened EVENLY.
7. See section 4.2.3 to check &/or correct the packing gland lubrication.
