Manhole Head 160/32 Steel, Galvanized Cover, for Deep Well

Galvanized Manhole Head Size 160/32

Through manhole head for 160 mm well pipe to 32 mm deep well 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 deep well operation. 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

✅ Additional mounting hooks ensure comfortable installation and facilitate manhole head removal.

✅ 6 clamping bolts provide perfect sealing of the manhole head on both the well pipe and the deep well pump delivery hose.

The manhole head, made from appropriate materials, ensures a perfect seal for the deep well.

✔️ Robust steel construction allows secure tightening of the clamping bolts. Our manhole heads use class 8.8 bolts. These classes indicate the tensile strength of the bolts, which translates to minimized 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 connections 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 manhole head servicing.

✔️ The gasket used in this manhole head is designed to perfectly fit both the well pipe and the deep well pump delivery hose, ensuring a hermetic seal. Thanks to proper sealing parameters, the manhole head is stably 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 deep well pump cables with a diameter of 12-18 mm. Our glands are equipped with a cable seal; the seal under the gland securely protects the threaded connection.

✔️ The additional technical plug features an integrated sealing lip. The plug design prevents contaminants from entering. The plug 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:

The manhole head fits a well pipe with an outer diameter of 160 mm. Maximum well pipe wall thickness is 8 mm.

Preparing the installation site:

✅Ensure the manhole head installation site is properly prepared:

✔️ Install the manhole head on the pipe body - not on the socket. The well pipe socket must be carefully and evenly cut off.

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

Manhole head dimensions:

ØD1 - 160 mm – diameter matching the outer diameter of the well pipe.

ØD2 - 144 mm – diameter of the seal designed for installation 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 manhole head is not compatible with sewer pipes.
