Winterizing SealMaster® Equipment

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.

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.
