Item NO.:
Grand 32-11 Pro1. Domestic heating and water supply system
2. Air and ground source heat pump system
3.Air-conditioning system
4. Industrial hot water circulation system
5.Solar thermal system
6.Compatibility with R290 All Inverter Heat Pump
Easy installation and operation
Equipped with Self Adapting mode AUTO (default setting), pump runs once the power is connected and adapts its performance according to actual system needs.
Control is effected by digital pulse-width modulation (PWM) low-voltage signal, enabling the pump to be used to meet different flow requirement in various systems.
Low noise and high comfort
Precise flow feedback,±0.2m³/h
Noise index＜36dB(A), especially in heat pump system
Suitable for Propane refrigerant, such as R290
Low energy consumption
Lowest power consumption up to 2W
Multiple protection
With over-voltage and over-current protection
Eco-Design Benchmark
EEI≤0.20-Part 3
Quick release power plug
Start-up and stop the pump quickly.

Service environment requirements
The working environment temperature of the pump should be synchronized with themedium temperature of -20~95℃, as shown in the figure on the right (the maximum ethylene glycol concentration is 50%, that is, the medium The minimum temperature is -30℃
Start and stop of pump
Starting time: the starting time of the water pump is less than 8S, the timefrom power on to reaching the maximum speed
In PWM mode, when starting from the stop state of the water pump (without powersupply), 90% of the maximum speed must be reached in at least 8 seconds
In PWM mode, start from standby mode and reach 90% of the maximum speed inat least 8 seconds
Shutdown time: the shutdown time of the water pump is less than 1 s, that is,the time from power failure to shutdown of the water pump
Power connection
Voltage：220-240V AC(±10% )
Frequency：50/60Hz
PWM input signal voltage：4-24V
minimum input current：4mA
PWM input signal frequency: 100-2000Hz
PWM output signal: collector open-drain output, must be connected to a pull-up resistor,the voltage is selected according to the signal acquisition range of the host computer
Installation Drawing
This performance curve is suitable for normal temperature water, if the pump is used for non-water medium, the hydraulic performance of the pump will be reduced , therefore, in the selection of pump, must consider the characteristics of the liquid medium.
Performance curve under different duty cycles in PWM mode (for reference only）
