Product Overview

The APT-60H is a 60-liter (14-gallon) horizontal diaphragm pressure tank designed ESP booster pump systems using 1.5 HP motors. It stabilizes water pressure and reduces pump cycling.

APT-60H 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 directly with the tank shell, ensures safe operation for cold sanitary water circuits, pressurized systems, and water storage applications. Its horizontal configuration makes it ideal for space-limited installations, pump skids, and compact residential booster systems.

Manufactured with premium materials and certified by NSF, CE, WaterMark, IAPMO, and other international bodies, APT-60H 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.

Materials & Design Advantages

How the Pumplus Pressure Tank Works

APT-60H 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.

  • Small commercial and public facilities

Frequently Asked Question (FAQ)

Q1 : Is a 60-liter (14-gallon) tank sufficient for a 3–4 story building? How do I choose between APT-60H and APT-80H?

A: Yes. A 60-liter (14-gallon) tank is generally sufficient for most 3–4 story homes with 7–10 people. The APT-60H can support 6-7 faucets running at the same time, provides stable water pressure for showers, and can reduce significantly booster pump start/stop frequency by over 60%. 

If your home has 10-14 people, or frequent high-volume, simultaneous water usage -> Choose APT-80H. It supports 7-8 faucets at once and offers greater reserve capacity.

Quick guide: 
APT-60H: 7-10 people, 3-4-story, 6-7 outlets. 

Q2 : Can I install the APT-60H myself (DIY)?

A: We strongly recommend having the APT-60H installed by a qualified plumber or technician for the following reasons:

Safety & Proper Setup: The APT- 60H  is a pressure vessel, and correct installation is critical. A professional will ensure:
• The pre-charge pressure is set correctly (typically 2 PSI below the system cut-in pressure).
• All pipe connections are properly sealed and leak-free.
• The installation location can safely support the unit's weight.

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.

Q3 : Does the APT-60H require regular maintenance? How long should it be replaced?

A: The APT-60H is designed to be “maintenance-free”.

  • No regular maintenance required.
  • No filter elements or consumables need replacement.
  • No air recharging needed during normal use (we use 100% Nitrogen pre-charge, which won't leak like air).

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-60H 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.
