Non Negative Water Pressure Pump Constant Variable Frequency Water Supply Equipment
Comparison of mainstream equipment types and technologies
1. Non negative pressure water supply equipment (pipeline direct connection type)
Principle: Directly pump water and pressure from the municipal pipeline network, without setting up a water storage tank, and use a stabilizing tank to compensate for pressure fluctuations
Advantages:
✅ Eliminate secondary pollution (closed operation)
✅ Energy saving of over 40% (utilizing residual pressure in the pipeline network)
✅ 50% land saving (no need for water tank)
Limitations: The municipal pressure must be ≥ 0.2MPa and the flow rate must be sufficient, otherwise it may cause a water outage
Applicable: Mid to low rise residential and commercial complexes
2. Variable frequency constant pressure water supply equipment (water tank+pump set)
Principle: Municipal water enters the water tank first, the water pump pumps water from the tank to increase pressure, and the variable frequency maintains the set pressure
Advantages:
✅ Unrestricted by municipal pressure, high reliability of water supply
✅ Can integrate water purification modules (such as iron and manganese removal devices)
Limitations: Regular cleaning of the water tank is required, which poses a risk of contamination
Applicable: Super high-rise buildings (>100m), renovation of old residential areas
3. Box type non negative pressure water supply equipment (Hybrid type)
Principle: Combining the advantages of the first two, municipal water is prioritized for direct supply, and when insufficient, water is replenished from the water tank
Technical highlights:
✅ Dual water source intelligent switching, zero water outage risk
✅ Dynamic circulation of water in the tank to avoid stagnant water areas
Applicable to scenarios with high requirements for water supply continuity, such as hospitals and data centers
