2 Seven Core Product Advantages
Top Pull-Out Design, No Pipe Disassembly For Maintenance Optimized rotor pull-out structure, inspect mechanical seal & clean impeller without removing inlet/outlet flanges, cut maintenance time by 70%, ideal for hospital & malls with non-stop water demand.
YE3 Class 1 High Efficiency Motor Save Power Yearly National Grade 1 energy efficiency, save over 20% electricity annually compared with traditional Y-series pumps, obvious energy benefit for multi-pump large machine rooms.
Low Noise CFD Optimized Hydraulic Channel CFD simulated closed impeller, double dynamic balance + SKF silent bearing, full load noise ≤58dB, no noise disturbance near offices & ward areas.
Wide Temp Adapt For Cooling & Heating All Year Suitable for low temp chilled water & high temp heating water, cover -15℃ anti-freeze condition up to 110℃ heat exchange medium.
Built-In Multi Safety Protection Motor overload, phase loss, overheat & stall protection integrated; optional dry run relay auto shut down to avoid seal & impeller burnout.
Dual Impeller Material For Different Water Quality Standard cast iron for regular tap water; 304 stainless steel for softened & slightly corrosive water, no rust blockage during long operation. 7 Two Mounting Types Fit All Renovation Projects Vertical & horizontal options, no full pipeline reconstruction required for old buildings. Vibration base & VFD accessories one-stop supporting.
3 Standard Installation Requirements
Piping: Install flexible rubber joints at inlet & outlet, keep straight pipe ≥5 times diameter before & after pump;
Fixing: Vertical pump connect vertical pipe directly, horizontal pump must match vibration base;
Electrical: Independent power supply for VFD model, add filter reactor to reduce interference;
Medium: Clean water / softened water only, Y-strainer installed at front to block hard sediment;
Anti-Freeze: Drain pump cavity for long winter shutdown, heat tracing accessory optional.
4 Main Application Scenarios
Commercial Buildings: High-rise offices, star hotels, grade A hospitals, shopping mall chilled & heating water circulation;
Industrial Plants: Production chiller & plate heat exchanger water system;
Renovation Works: Old low-efficiency pump energy replacement project;
Supporting Equipment: AHU, air-cooled & water-cooled unit matching circulation system.
5 Routine Maintenance Guide
Monthly: Check noise, vibration & inlet/outlet pressure difference;
Quarterly: Clean front strainer, inspect mechanical seal leakage;
Yearly: Refill bearing grease, test motor insulation resistance;
VFD Pump: Calibrate differential linkage parameter regularly to avoid low-load idle operation.
