Tanks with overpressure

BUPOLSA’s pressure or vacuum tanks are made of glass fibre reinforced polyester (GRP) and are an essential element for storage or for use in pressure processes, such as pneumatic impulsion of liquids, gas saturation on liquid, cartridge filters, sand filters, etc. These tanks are designed to contain both fluids and gases at pressures higher than environmental or atmospheric pressure.

These types of tanks are manufactured for Vertical models with legs and Horizontal both aerial and buried, and they can have all the necessary accessories to satisfy the customer’s needs.

By means of the suitable choice of the type of resin and the correct dimensioning of the thickness of the walls, deposits capable of withstanding working pressures between -1 and +10 bar are obtained. All equipment will be supplied with its corresponding Certificate of Conformity (Installation instructions).


You can consult the available capacities for each type to our technical sales department.


Advantages of pressure equipment manufactured in PRFV:

  • High durability in corrosive environments and extreme environmental conditions.
  • Low maintenance.
  • Optimum behavior in front of the fluids to filter.
  • Great resistance to both low -30ºC and high -210ºC temperatures thanks to the variety of resins with which the equipment can be manufactured: orthophthalic, isophthalic, bisphenolic and vililester.
  • Low thermal conductivity.
  • Equipment that is easy to transport and lightweight.
  • Personalization of each equipment according to specifications and needs of each client.
