APT-160 is designed for large households, villas, and small commercial buildings with heavy water usage.
APT-160 has a total volume of 160 liters (44 gallons). The tank is designed for a maximum operating pressure of 10 bar (150 psi) and a maximum operating temperature of 90 °C (194 °F). It is factory pre-charged to 3.1 bar (45 psi) for stable system performance.
With a diameter of 55.0 cm and a height of 93.3 cm, the weight 23.9 kg design makes installation quick and convenient while saving space.
Product Overview
The APT-160 is a 160-liter (44-gallon) diaphragm pressure tank designed for high-flow residential, public, and light-commercial booster pump systems. It stabilizes water pressure and reduces pump cycling.
APT-160 is ideal for regions with unstable or fluctuating municipal water pressure, widely used in homes and buildings where booster pumps are required. Its hygienic internal design, separate water from compressed gas and prevent water contact direct with the tank shell, ensures safe operation for cold sanitary water circuits, pressurized systems, and water storage applications.
Manufactured with premium materials and certified by NSF, CE, WaterMark, IAPMO, and other international bodies, APT-160 complies with global standards including those in the United States, Europe, Australia, and Asia. Produced in ISO-certified facilities, Aquasky pressure tanks delivers long service life, dependable performance, and safe drinking-water compatibility.

Key Features & Design Advantages
How the Pumplus Pressure Tank Works
APT-160 stores supplemental water between the butyl rubber diaphragm and the polypropylene liner, while the nitrogen-filled air chamber maintains constant system pressure. When water demand occurs, the compressed nitrogen pushes water into the system at a controlled pressure.
This design ensures stable performance and supports reliable operation for showers, faucets, dishwashers, washing machines, and other fixtures.

Typical Applications
Frequently Asked Question (FAQ)
A: Yes. A 160-liter (44-gallon) tank is generally sufficient for most large villa or small hotel. The APT-160 can support up to 50 L/min and significantly reduces pump cycling while maintaining strong pressure.
If your building has higher water demand, long piping distance, or public-use demand → choose APT-200 for higher flow stability.
Quick guide:
APT-160: Large villas, small hotel, water usage ≤50 L/min
APT-200: Apartments, dormitories, water usage ≤60 L/min
A: We strongly recommend having the APT-160 installed by a qualified plumber or technician for the following reasons:
Safety & Proper Setup: The APT-160 is a pressure vessel, and correct installation is critical. A professional will ensure:
System Compatibility: The tank must be correctly integrated with your booster pump, pressure switch, and piping system to ensure stable performance and avoid operational issues.
Warranty Protection: Installation by a non-professional may affect your product warranty coverage.
A professional technician can typically complete the installation, testing, and calibration within 2–3 hours.
A: The APT-160 is designed to be “maintenance-free”.
Simply check the pre-charge pressure once every 1–2 years using a standard tire pressure gauge. If the pressure is low, you can refill the Nitrogen by yourself or ask a plumber to do it.
Service Life: Under normal operating conditions (water temperature ≤ 99°C, pressure ≤ 10 bar), APT-160 designed to last over 10 years. Many of our customers have used it for over 15 years with normal operation.
Warranty: We offer a 3-year factory warranty covering manufacturing defects and material flaws.
Installation Tip: Ask your plumber to measure your water pressure during installation and recommend the most suitable system configuration.
