Manhole Head 125/32 Galvanized Steel Manhole Head

Galvanized Manhole Head Size 125/32

Through manhole head for 125 mm well pipe to 32 mm submersible pump delivery hose.

The manhole head is a key component of the well system designed to protect the water intake. It provides a hermetic seal, minimizing the risk of water contamination in the well from external factors such as atmospheric debris, groundwater, soil contaminants, and small animals. All these factors can degrade water quality and negatively affect the operation of the deep well. Our manhole head eliminates these risks.

Specifications:

✅ Material: galvanized steel.

✅ Seal: SBR.

✅ Bolts and safety cable eyelet: galvanized steel.

✅ Cable gland for 6-12 mm diameter cable.

✅ Technical plug.

✅ Thread connection protectors: plastic.

✅ Max suspended load: 140 kg

The manhole head ensures a perfect seal for the deep well thanks to the use of appropriate materials.

✔️ Robust steel construction allows secure tightening of the clamping bolts. We use class 8.8 bolts in our heads. These classes indicate the tensile strength of the bolts, which helps minimize installation issues such as bolt breakage or thread damage during assembly.

✔️ Steel flanges do not deform when tightening bolts - unlike plastic manhole heads.

✔️ Choose additional protective caps for nuts in our store – these further protect threaded connections. Protecting threaded joints is especially important against solid contaminants inside the well casing. Hex nuts reduce problems related to bolt thread damage or the need to clean Allen bolt sockets during head removal for maintenance.

✔️ The gasket used in this manhole head is designed to perfectly fit both the well pipe and the submersible pump delivery hose, ensuring a hermetic seal. The seal parameters ensure the head is firmly seated on the pipe – the gasket does not push the head off the well pipe when tightening bolts.

✔️ The manhole head includes a cable gland for submersible pump cables with a diameter of 6-12 mm. Our glands feature a cable seal, and the seal under the gland ensures a tight threaded connection.

✔️ The additional technical plug has an integrated sealing lip. The plug design prevents contaminants from entering. It can be unscrewed using a screwdriver, socket wrench, or by hand.

The plug provides access to the deep well without removing the manhole head.

Installation Information:

This manhole head fits a well pipe with an outer diameter of 125 mm marked PN 10 - 125x4.8 - for pipe wall thickness 4.8 mm.

WE ALSO OFFER HEADS FOR THICKER WALLS (PN 12.5, PN 16). PLEASE LEAVE A MESSAGE IF YOU NEED A HEAD FOR WELL PIPES WITH WALL THICKNESS GREATER THAN 4.8 mm.

Preparing the installation site:

✅ Ensure the manhole head installation site is properly prepared:

✔️ Install the head on the pipe barrel - not on the socket. The well pipe socket must be cut cleanly and evenly.

✔️ Clean the well pipe from any debris and residues to ensure proper seating of the head.

Manhole head dimensions:

ØD1 - 125 mm – diameter matching the outer diameter of the well pipe.

ØD2 - 114 mm – diameter of the seal designed to fit inside the pipe with diameter D1.

H - 32 mm

IMPORTANT

The manhole head is compatible with blue well pipes according to PN-G-02323 standard - used in deep wells meeting pressure standards with appropriate wall thickness.

.

The head is not compatible with sewer pipes.
