Product Overview


Basic Specifications

The YC-S-400 is a PM VFD Constant Pressure Pump in the YC-S series, specialized in maintaining stable water pressure for clean water applications. It has a rated power of 400 W, rated voltage of 220 V, and rated current of 3.1 A. Performance specs: rated flow 2 m³/h, rated head 23 m, maximum flow 3.8 m³/h, maximum head 45 m. It features 4 impeller stages, a wide speed range of 1000~5100 r/min, DN25 inlet/outlet size, F-class insulation, IPX4 protection, and a water temperature limit of ≤95 ℃. Medium requirements: pH 6.5–8.5, solid impurity volume ratio ≤0.1%, particle size ≤0.2 mm.


Core Function

Its “constant pressure” technology uses PM VFD to adjust speed in real time—if pressure drops (e.g., multiple faucets open), it increases speed; if pressure rises (e.g., faucets close), it slows down. This ensures consistent water pressure for all users.


Key Features


Precise Constant Pressure: Maintains stable water pressure regardless of flow changes, eliminating sudden pressure drops in showers or uneven faucet flow in multi-user homes.

High-Speed Adaptability: 1000~5100 r/min speed range (wider than many models) handles varying demands—from 2 m³/h rated flow for daily use to 3.8 m³/h max flow for peak times.

Energy & Cost Savings: 30%–50% energy reduction vs. traditional pumps. By only using power needed to maintain pressure, it lowers electricity bills long-term.

Durable & Safe: F-class insulation resists high temperatures (up to 95 ℃ water), while IPX4 protection prevents splashes from damaging the motor. 4 impeller stages enhance pressure stability and wear resistance.


Scenario-Specific Solutions


Multi-Story Residential Pressure Maintenance: Ideal for duplex apartments or villas with 2+ floors. It keeps pressure consistent on all floors—no weak flow in upper-floor showers or excessive pressure in lower floors. The constant pressure feature also prevents pipe damage from pressure spikes.

Household Tap Water Pressurization: For homes with low municipal water pressure, it boosts pressure to ensure strong flow in faucets, washing machines, and dishwashers. Its compact DN25 size fits standard residential pipelines.

Hot Water & Solar Circulation: Withstands up to 95 ℃ water, making it suitable for bath club hot water systems or solar water heaters. It circulates warm water evenly, and constant pressure ensures consistent temperature at all outlets.
