The stainless steel non-negative pressure flow tank equipment is a new generation of water supply equipment newly developed and manufactured. This equipment utilizes vacuum treatment technology, allowing direct connection of the water supply system to the municipal water network without creating negative pressure, thereby not affecting the normal water supply of the municipal water network and eliminating the need for construction of reservoirs or water tanks.
The device pressurizes tap water directly for residents, featuring fully sealed connections and all flow components are sanitized, ensuring no contamination of the water source. The equipment employs variable frequency speed regulation for constant pressure technology, stabilizing water supply pressure with minimal fluctuations.
Directly connected to the municipal water supply network, the equipment utilizes the existing pressure in the network. It activates when the pressure is insufficient, continuing until the set value is reached, and stops when the water pressure in the network meets the requirements. This device reduces construction costs, eliminates secondary water pollution, and boasts advantages such as energy saving, convenience, high level of automation, and reliability. It is an ideal product for improving water supply quality.

Product Features
No need for pond construction to save costs and energy
Traditional water supply methods require reservoirs, usually supplied by the municipal water network. As a result, the existing pressure is released for zero utilization, leading to significant energy waste. This equipment eliminates the need for a reservoir, saving over 50% of the construction costs and, compared to other water supply equipment, can save 20-40% of electricity.
Water supply without pond also available
The key component of this unit, the flow regulator tank, is available in carbon steel and full stainless steel types. The carbon steel type features an advanced "841 epoxy polyamide coating" for corrosion resistance on the inner wall. The tank is tightly sealed, preventing vacuum formation that could damage the water supply network or affect water usage for surrounding users. Water supply continues during power outages; when the power is off, the equipment automatically resumes the normal water supply at atmospheric pressure.
Selection Guide for Stainless Steel Non-Drainage Flow Stabilization Tank Equipment
The selection of the stainless steel non-negative pressure flow storage tank water supply equipment is determined based on the user's tap water inflow (i.e., tap water pipe diameter, pressure), actual water usage, and building height data. The volume of the storage tank is estimated to meet the tap water flow requirements. If the tap water pipe diameter is small and the flow cannot meet the water usage requirements during peak periods, the volume of the storage tank needs to be recalculated, using the following formula:
v Volume = (Q_out - Q_in) * A * t
Q Inlet — Potable Water Inflow Rate During Peak Water Usage (m³/h)
Peak Water Usage by Customers (m³/h)
Duration of Water Peak Usage (h)
