Product Description
Household Self-Priming Pump Pressure Tank — Reliable Water Pressure Solution
This diaphragm-type pressure tank is designed for use with self-priming pumps and booster pump systems. It maintains stable water pressure, prevents frequent pump cycling, and extends the service life of your water pump.
How it works: The tank uses a pre-charged nitrogen chamber separated from the water by a flexible butyl rubber diaphragm. As water enters, the compressed air maintains constant pressure, reducing pump starts by up to 60%.
6 sizes available: 19L, 24L, 36L, 50L, 60L, and 80L. Choose based on your system’s water demand and pump flow rate. Suitable for household water supply, garden irrigation, small farm applications, and light commercial use.
Durable construction: Carbon steel shell with anti-corrosion coating. Food-grade butyl diaphragm. Standard threaded connection for easy installation.
