Tips for Preparing Pumps for Winter

Winter can wreak havoc on pumping equipment. Brutally low temperatures and ice buildup can cause serious internal and structural damage, leading to costly repairs and downtime. That’s why proper winter preparation isn’t just a good idea – it’s a must. At Mersino Water Solutions, we follow a thorough winterization process for our pumps, whether they’re idle in the yard or gearing up for the next job. Here are a few critical steps we take to ensure our pumps are ready to operate in winter conditions.

Prepare Fluids

When a pump has been sitting idle in freezing temperatures for long periods of time, it’s imperative that to not just walk up and start it. One of the first steps we take is test the oil and antifreeze by using a hydrometer to make sure the antifreeze can handle the cold.

In below freezing situations, we mix an additive in with the fuel to prevent it from thickening. If we find the fuel has thickened, other additives can be mixed in to loosen the fuel and allow it to flow easier through the engine. Checking the fluids in the pump end is equally as important as checking those in the engine itself. Therefore, we also confirm the fluid in the seal reservoir is full and not leaking.

Check the Tire Pressure

Much like the tires on your car, the tires on our trailer mounts run the risk of depressurizing during winter time. We simply check the tires with a standard gauge to ensure the pressure is at a standard 35 psi.

Ball Valves are Open Pre-Start Up

Both ball valves, one on the casing and one on the discharge check valve, should be left open to allow any preexisting water to be drained out. If left closed, any water inside the unit will potentially freeze and cause structural damage.

Check the Battery

To allow the engine to run properly, we provide suitable protection to prevent the battery from freezing. If needed, we’ll even remove and store the battery in a climate-controlled environment.

Test the Control Box

Oftentimes, if the fluids are too cold, the engine will have difficulty turning over. When checking the control box, we look to see if the starting aid is active, which allows the fuel and oil to preheat before fully turning over the engine.

Watch the Fan/Fan Belt

After the engine successfully turns over, we check the fan and its belt to make sure everything is rotating smoothly. When there’s ice present, the alternator will be unable to rotate, potentially leading the belt to break.

Conclusion

Following these steps for winterization is essential for maintaining the quality of our equipment, extending its lifespan, and reducing repair costs. Prepare your pumps for these harsh conditions and keep your operations running well this winter.
