FILTERS & PUMPS

The design of the top cover allows for easy and comfortable access to the inside of the tank for easy maintenance operation.

  • BWS grande continues with the tradition of BWS sand filters, recognized for their strength and reliability.
  • The filter tank is made of an inner fibreglass bladder with a high pressure capability.
  • The gel coat layer is then continuously wound with fibreglass strands to create a high strength vessel.
  • This process is recognized as one of the strongest methods of manufacturing a non corrosive high strength filter tank.
  • All components are injection moulded from high strength engineering plastics.
  • The fiberglass base makes it strong and durable.
  • Available from 1050mm/42” up to 1200mm/48”.
  • The maximum working pressure is 2,5Kgs/cm2.
  • BWS grande sand filters go together with valve for models using 2” valve or 3”flange.

Inner component materials are made of the latest generation of plastic resins.

  • BWT sand filters go together with valve for models using 1,5” and 2” connections.

marathon - Its hydraulic design moves water more efficiently and quietly than any other pump in its category.

  • The Marathon pump is built to be quiet, durable and reliable.
  • The motor materials are rustproof, with a stainless steel motor shaft and sealed bearings that never need lubrication. The thermoplastic housing is built to withstand extreme heat and resist corrosion.
  • New Marathon can deliver cost benefits as it moves the same amount of water but consumes less energy than the previous model.
  • It includes a pre-filter with a large strainer to prevent the entry of any foreign objects which could cause damage to the hydraulic parts of the pump.
  • Large strainer basket extends time between cleaning.
  • See-through lid makes inspections fast and easy.
  • Options include a 316 SS shaft for salt water. 230 V and 60 Hz motors as well as Thai, Australian and British connections.
  • TUV GS Certified.
