CXGPM Intelligent Inverter Circulation Pump

Suitable for residences with an area of 100~200㎡ (e.g., three-bedroom two-living-room apartments, first floor of villas). The AUTO adaptive function can automatically adjust the flow rate and lift according to the indoor-outdoor temperature difference and the heating demand of rooms. For example, in winter, when there are many people indoors during the day and the temperature demand is high, the pump automatically increases its power; at night, the optional "automatic night speed reduction" function can be activated, reducing energy consumption by 20%~30 while avoiding balance valve noise. It is particularly suitable for double-pipe heating systems, as it can accurately match the differences in heat demand between rooms and reduce the problem of "uneven heating and cooling".

Used for hot water circulation of gas/electric water heaters in residences with multiple bathrooms (e.g., villas, duplex buildings). Through frequency conversion adjustment, it ensures stable water temperature in the hot water pipes of each bathroom (e.g., maintaining 40~50℃), so that hot water flows out immediately when the faucet is turned on, avoiding the need to wait for cold water to drain when using water across floors. With a medium temperature range of 2~110℃, it can adapt to the high-temperature hot water output by water heaters (≤70℃). Moreover, its energy-saving feature can reduce the energy consumption caused by repeated heating of the water heater, lowering the total domestic electricity consumption.

Applicable to heating and hot water circulation in guesthouses (10~20 rooms), small hotels (fewer than 30 rooms), and office buildings (1000~2000㎡). Medium-to-high flow models (e.g., GPM25-12-130 with a flow rate of 7.6 m³/h) can meet the demand for simultaneous water use by multiple users. The proportional pressure difference control function can avoid excessively high lift caused by changes in system resistance, reduce balance valve noise, and improve the quietness of commercial spaces. With an IP42 protection rating, it is suitable for humid environments such as boiler rooms and bathrooms, requiring no additional protection.

: No manual debugging is required. The pump automatically learns system characteristics and optimizes to the optimal operating state within 1-2 weeks, adapting to mainstream systems such as underfloor heating and double-pipe heating. Parameters are automatically saved after power outage, and no reconfiguration is needed when power is restored, making it suitable for non-professional users.

Flexible Switching Between Multiple Modes: It supports 3 proportional pressure difference curves (PP1~PP3), 3 constant pressure curves (CP1~CP3), and 3 fixed-speed curves (S1~S3), which can be selected according to system types. For example, PP mode (adjusting pressure with flow changes) is used for underfloor heating, and CP mode (maintaining constant pressure) is used for hot water circulation, adapting to control needs of different scenarios.

Automatic Night Speed Reduction: Optional function. It judges the night period through a built-in pipeline temperature sensor (when the pipeline temperature stays at 10~15℃ for 2 hours and the cooling rate is ≥0.1℃/min), then automatically reduces the rotation speed. This ensures basic heating/hot water needs are not affected while achieving further energy savings.

Comprehensive Flow Rate and Lift Coverage: With a flow rate of 3~7.6 m³/h and a lift of 4~12 m, it covers needs ranging from "heating for small-to-medium apartments" to "small-to-medium commercial circulation". For instance, the GPM20 series is suitable for residences under 100㎡, while the GPM25-12 series is suitable for residences over 200㎡ or small guesthouses.

Medium Temperature Range: 2~110℃: It can transport cold water (air conditioning circulating water), warm water (domestic hot water), and medium-temperature liquids (heating hot water). Compared with conventional pumps (5~50℃), its applicable scenarios are expanded by more than double. One device can replace the combination of "heating pump + hot water circulation pump", reducing equipment investment.

System Pressure: 1.0MPa: It adapts to water circulation needs of 2~4-story buildings (such as multi-story guesthouses and office buildings). The inlet pressure is reasonably designed (e.g., minimum inlet pressure of 0.108MPa at 110℃), avoiding cavitation noise and bearing damage, and ensuring stable water supply for high floors.
