With so much moisture present during operation, Plastic Pump(KEXON) become notably vulnerable to damage in cold weather. Frozen water in your pump system can lead to crippling issues ranging from improper functioning and premature parts failure all the way to more costly damage caused by freeze-and-thaw issues or thermal shock.

The good news is — with a little preparation and careful operation — your system can be winterized without trouble. Here are five steps to help you maintain your system in extreme cold conditions:

1. Protect your pipes and pumps from the elements.

Since mechanical seals and bearings are particularly vulnerable to damage while operating in freezing conditions, protect them by heat tracing and wrapping your seal water piping. A heated shelter is ideal, but not every slurry pump in the Oil Sands has this luxury. If this is not practical, do not stop the slurry flow! Instead, find a way to protect your pump from the elements and use an appropriate heat source to raise the temperature of the bearing assembly, lubricating oil, and pump casing before starting it up. Look to your local codes to determine the most suitable heat source for the job.

2. Prevent freezing during shutdowns.

If you’re shutting your unit down in sub-zero conditions, make sure it’s completely free of water so it doesn’t freeze, expand, and result in damage. Some pumps are designed for periodical stops with built-in plugs in the shell base. However, other systems require you to remove the system piping and pump out the casing. Looking for another option? Install a dump valve in the lowest point of the piping system and use it. Whichever method you choose, don’t forget about the stuffing box and lines.

3. Check your oil.

Your pump’s bearings will need extra attention during the winter months. That’s because any moisture or condensation inside the bearing races will quickly turn to ice, preventing smooth movement in the assembly and resulting in damage and untimely failure. Before cold weather arrives, change your CBA oil and check the viscosity or “weight” of the oil against the coldest expected air temperature to ensure the oil is correct for the conditions. Depending on your bearing size, a synthetic oil may be recommended. Unlike traditional mineral oils, the pour point of synthetics is designed to maintain effective lubrication at low temperatures.

4. Prepare your pneumatics and v-drives.

If your isolation valves are pneumatically actuated, make sure your air dryer is functioning optimally. For v-drives, consider installing new belts for the winter so you don’t have to deal with replacing them when it’s negative 40-degrees.

5. Operate with care.

When operating your slurry system in a wintery environment, take care to properly start up and oversee your system. Your pump casing should always be brought up to operating temperature gradually, either with process flow or external heat, to prevent thermal shock. The stuffing box also needs a constant supply of water, which may need to be insulated or heated, and flush water must be drained to prevent ice buildup.

These tips should help you keep your slurry system in working order through the winter and beyond.It’s also important to keep in mind that pumps and slurry systems can be designed with harsh environments — and severe temperature fluctuations — in mind.
