Siphon pit Ø400

RASAN drainage manholes are made up of several elements manufactured in PE using the rotational moulding technique.

The manholes are supplied with the desired height and these elements are joined together to reach the required height.

The pits are supplied with the desired height and for this purpose these elements are joined together until the required height is reached.

The elements are joined together until the required height is reached.

The elements are joined together until the required height is reached.

The union of these elements is carried out with a continuous welding with a 250ºC material supply, which allows a perfect and stagnant union between the different pieces or also by means of a joint, in the event that it is preferred to assemble on site.

The polyethylene is made of polyethylene with a continuous welding process at 250ºC, which allows a perfect and stagnant union between the different pieces.

Polyethylene is perfectly resistant to all components of domestic and industrial wastewater and is resistant to most acids and aggressive salts.

Polyethylene is also resistant to most acids and aggressive salts.

The RASAN pits are available in 600, 400, 315 and 250mm diameters.

These can be supplied with the connections prepared according to the needs of the project or the connections can be made on site using bilabelled joints.

The inner bottom of the manhole is made of a stainless steel tube with a diameter of 600, 400, 315 and 250mm.

The inner bottom of the pit has a grooved shape that allows it to easily channel the water, preventing it from stagnating.
