DEEP WELL HEAD 110 mm - 114 mm

We recommend this head for hermetic sealing of deep wells.

Installation size of the head: for water supply PVC-U pipes 110 mm and 114 mm for blue well pipes

Based on installer feedback, our heads feature a special recessed flange allowing use with blue well pipes with an outer diameter of 114 mm.

The PE connection better supports the pump weight than rubber seals in pass-through heads.

The PE32 Jason connection can be replaced with any other manufacturer's connection when worn or damaged, eliminating the need to buy a new head as with competitors.

The head is a crucial component of a deep well. It primarily protects the well from groundwater flooding and prevents unwanted entry of solid contaminants such as silt, sand, stones, small rodents, etc. Installing this head helps avoid unpleasant consequences related to these hazards. It saves time, money, and protects health. Our heads have appropriate certifications for use in drinking water wells.

!!! IMPORTANT !!!

Our heads do not have ventilation. Is this a flaw or a benefit?

The purpose of installing the head is to achieve the best possible seal and protect the well from ingress of solid particles and groundwater or rainwater.

Manufacturers of ventilated heads argue that ventilation is needed to protect the pipe from damage caused by significant water level drops (vacuum) or inflows (pressure).

Assuming the well is made with standard casing pipes rated for 10 atm. In case of:

• water level drop - with a perfectly hermetic well, the water table can drop a maximum of 10 meters = 1 atm vacuum, which will not damage a standard well pipe rated for 10 atm. If water drops more than 10 meters, the well is not perfectly sealed and no vacuum forms to damage the casing pipe.
• water inflow - to damage the pipe, water pressure would have to reach 10 atm, which would mean a flowing well, which is not used. Also, if pumping causes water level drop creating vacuum, water inflow equalizes pressure in the pipe.

Disadvantages of well ventilation:

• Ventilation can allow groundwater or rainwater to enter the well, contaminating it, especially if the well is in a flood-prone area.
• If ventilation is above ground, heavy metals in the air can enter the well, and excessive air exchange promotes microorganism growth.

Construction:

• The head consists of two discs made of very durable material (PE-HD), with a rubber ring between them.
• The discs are connected with stainless steel screws that tightly and permanently clamp the head onto the well casing pipe.
• Our stainless steel mounting screws do not corrode, allowing easy removal even after long use. Other manufacturers use galvanized screws that corrode, making removal difficult after extended use.
• The head includes a PE JASON connection for PE32 pipe, a rope hanger for suspending the pump, and a cable gland for the electric cable.
• Hydraulic components are centrally aligned along the head axis, allowing easy installation of hydraulic fittings.
