Pressure tank Wimest GZ100 100 l galvanized hydropneumatic tank with fittings

Wimest GZ100 is a 100-litre galvanized hydropneumatic (pressure) tank supplied with the required fittings. Designed to stabilize water pressure in domestic and commercial pumping systems, it reduces pump cycling and provides a temporary reserve of water. The galvanized steel construction offers corrosion resistance suitable for wells, booster sets and water supply systems where robust metal tanks are preferred.

Advantages

The galvanized shell provides enhanced protection against rust and extends the service life compared with untreated steel. With a 100-litre capacity, the tank balances demand and pump operation to reduce frequent start/stop cycles, lowering wear on the pump and associated controls. Supplied with fittings, the unit is ready for integration into existing systems without additional sourcing of basic connectors. The compact vertical design allows installation in pump rooms, basements or tight technical spaces.

Suitable for

• Domestic water systems and households with well or municipal supply
• Booster pump installations and pressure boosting sets
• Small commercial premises with moderate water demand
• Systems where corrosion-resistant steel tanks are required

Key specifications

• Nominal volume: 100 litres
• Material: galvanized steel shell for corrosion protection
• Type: hydropneumatic / pressure tank with internal air cushion
• Orientation: vertical installation
• Connection: supplied with standard fittings for immediate installation
• Primary function: pressure stabilization and temporary water reserve

How to use

Install the Wimest GZ100 in a location that allows access for inspection and maintenance, positioned on a flat, level surface and secured if required. Connect the tank to the pump or system piping using the supplied fittings, ensuring correct sealing and tightness. Set the precharge pressure according to the pump controller manufacturer's recommendations and the system static pressure; check and adjust the air charge periodically when the system is depressurized. Verify all fittings and connections for leaks before returning the system to normal operation.

Usage recommendations

Maintain the tank by checking the precharge pressure at least twice a year, inspect for signs of external corrosion or damage to fittings, and ensure the installation area is frost-protected if used in low-temperature environments. Replace worn seals or fittings promptly to preserve performance and prevent water loss.
