Winterizing SealMaster® Bulk Storage Tanks

1) Winterizing the Tank

  • Grease the packing glands and bearings.
  • Flush the inside of the tank completely with water.  A pressure washer is recommended for this.
  • Pump the wash down water and sealer residue out through the pump and hose into a container.
  • Remove plug from the bottom of storage tank and allow any remaining water to drain out into a container.  Grease the threads on the plug and replace plug immediately.
  • Remove and clean the basket strainer.
  • Turn pump on, with basket strainer lid opened, and flush basket strainer with clean water. Mix up to 2 gallons of antifreeze solution and flush that through basket strainer and pump.
  • Remove battery and store inside.
  • Close manhole on top of tank to prevent rain and snow from entering tank.

2) Winterizing the Pump

  • Remove the rear housing of the material pump.
  • Pull out the lower pump gear and thoroughly wash with water.
  • Rinse out the pump housing.
  • Brush oil on all interior parts of the material pump including gears, housing, back plate and bolts.
  • Slide rear housing plate back onto material pump.  Replace bolts but do not tighten.  Be sure to leave a gap between the housing plate and pump housing.  This must be done to prevent pump from cracking during the winter.

3) Winterizing the Engine

  • Remove spark plug and spray W-D 40 (or similar penetrating oil) into the cylinder and replace spark plug.
  • Cover and wrap the engine with plastic or canvas to protect from weather.

4) Winterizing the Hydraulic Valves

  • Shift forward/reverse agitator valve into position to protect the spool valve from the weather.
  • Close the agitator speed control valve to protect the valve shaft from the weather

5) Chipping and Cleaning the Inside of Bulk Tank

NOTE – Temperature should be below 32° F when chipping sealer on inside of tank.  Colder temperatures will cause the dried sealer to be more brittle, making the job much easier.  Please be sure to follow Lock Out/Tag Out and Confine Space Entry procedures when entering tank.

  • Remove clean-out cover from the rear of the tank.
  • Use an air-opened chisel with a 2-inch spade bit to remove dried sealer.  Wear proper hearing protection.
  • Start chipping at the top of the tank and work your way down the sides of the tank.  Use a shovel to remove accumulated sealer chunks out through the clean out hole.  Be sure to chip and remove the sealer from the agitator shaft and blades.

6) Spring Start-up

  • Tighten the bolts on the pump housing plate.
  • Uncover the engine and replace battery.
  • Put 50 gallons of water in sealer tank and check for leaks.
  • Start engine and pump water out.

Winterizing SealMaster® Equipment

1) Pump-Out Option for Winterizing Pump Equipment:

  • Fill material tank with approximately 50 gallons of water and agitate well.  Pump the water out through the spray wand and spray bar.
  • Disconnect the spray hose and lay it on the ground in a fully extended position allowing it to drain completely.
  • Find the lowest point on the material pump plumbing system and open drain valve or remove plug.
  • If you have a Roper, Bowie, or similar type gear pump:  Loosen all of the bolts on the backplate.  Separate the endplate from the center case so that the water drains out.  Leave end plates separated over the winter.
  • If you have an air diaphragm pump:  Disassemble the pump and allow water to drain out.  Leave pump disassembled over the winter.

2) Antifreeze Option for Winterizing Pump Equipment

  • Rather than disassembling pumps for the winter, you may elect to pour a couple of gallons of propylene glycol into the basket strainer.  Turn on the pump to distribute the antifreeze throughout the system.  In the spring time you will need to flush the system thoroughly with water and dispose of the waste water properly.
  • To winterize water tank system, remove the drain plug on the water tank and water pump and allow to drain completely.  Or you can run antifreeze through the system, making certain to flush thoroughly in the springtime.
  • Drain all gasoline from engine.
  • Disconnect the battery and take it inside your building.  Wash battery with a solution of baking soda and water.
  • Cover the engine with a plastic trash bag.
  • Cover any locking caps with small plastic bag.
  • Put a thin layer of grease on any exposed hydraulic cylinders.
  • Scrape any sealer residue from inside the tank and on the outside of the machine.
  • Now is the time to do any necessary maintenance and repairs.
  • Sandblast and repaint.

3) Crack Sealing Equipment

  • Remove gasoline and oil; replace filters.
  • Cover the engine with a plastic trash bag.
  • Remove and replace the old Heating Transfer Oil with new, and replace the burner nozzle if necessary.
  • Flush the tank with the old transfer oil to melt and clean the system (DO NOT ALLOW MELTER TO HEAT OVER 300°F).  Let it run most of the day to remove build up.
