Deep well pipes

Deep well pipes are used to make a well structure consisting of:

  • - well pipe or casing pipe / above-filter pipe
  • - filter pipe
  • - end pipe / precipitator

Well pipes are used in:

  • - drinking water supply
  • - irrigation
  • - drainage (drainage of soil)
  • - geothermal energy

Well pipes are made of PVC polyvinyl chloride and with special additives provide an extremely long service life of wells.

Advantages of PVC well pipes:

  • - do not corrode
  • - thanks to their low specific weight, they are easy to manipulate
  • - healthy for drinking water
  • - easy to install
  • - chemically resistant
  • - ecological product - does not pollute the environment
  • - suitable for recycling
  • - long-lasting

Filter pipes coated with quartz granulate

These filters are made of quartz granulate bonded with an extremely strong, waterproof two-component epoxy resin. Quartz granulate is pure and rounded (96% SiO2) and three basic sizes are used in the production of filters:

  • - from 0.5 mm to 1 mm
  • - from 1 mm to 1.6 mm
  • - from 2 mm to 4 mm

We have provided a certificate for the health safety of water, suitable for drinking water supply.

A good well filter should meet and provide the following:

  • - to prevent uncontrolled discharge of aquifer material into the well
  • - to enable minimal resistance to groundwater movement
  • - to enable the maximum yield of the well
  • - that it is simple in construction, easy to install
  • - to be durable and resistant to the chemical action of groundwater
  • - to be resistant to external lateral pressures
  • - to have sufficient throughput
  • - to prevent the passage of granular well backfill or material in the well during pumping
  • - to enable rinsing and elaboration of wells
  • - to ensure the assembly and disassembly of the pump in the well without damage
  • - to enable a long service life of the well
