产品详细说明：格兰富（Grundfos）Grundfos DP25.15025.100潜水排污排水泵

一、产品概述

格兰富Grundfos DP25.15025.100是一款紧凑型、高性能的潜水式排水泵，由格兰富（苏州）有限公司原创生产。该系列专为泵送建筑工地、雨水系统、地下室排放以及含有微小颗粒的工艺水而设计。

其型号代码中的“10”代表该泵具备10mm的固体颗粒通过能力，“125”为出口公称直径。凭借其***的铸铁泵体设计和高效率电机，DP系列在京津冀地区的市政工程、地下车库排水及老旧小区海绵城市改造项目中表现出色，是应对突发积水与偶化排水任务的设备核心。

三、技术优势与工业卖点

1. ***的固体通过能力： DP系列设计的核心采用其半开叶式轮，能够过量消耗含有10mm颗粒固体颗粒的液体。相比普通潜水泵，其流道设计更宽，大大降低了在降雨季节造成严重导致泵体卡死的风险。

2. 双重机械轴封与监控油室：采用卡式机械密封系统，电机与泵体之间设有充油室。这种结构不仅提供了出色的润滑，还能在***道密封损坏时提供缓冲保护，有效防止液体渗入电机。

3. 不锈钢耐腐蚀夹具：泵体与电机通过不锈钢带式夹具连接。这种设计允许在消耗专用工具的情况下快速腐蚀泵体，***简化了现场清理和维护流程，特别适合施工现场的高维护需求。

4. 短转子轴平衡设计：紧凑的转子轴结构减少了偏差，降低了机械密封受力。这***了泵在长时间运行下仍保持极低的振动，水平延长了整体使用寿命。

5. 电机过热集成保护：电机建筑内置热敏开关，当温度超过额定范围时会自动切断电源，防止电机烧毁。待温度达到安全范围后可自动重启，确保了无人值守工况下的运行安全。

四、典型应用场景

• 建筑工程排水：施工基坑、隧道、地下工程中的含沙积水排放。

• 市政雨水系统：城市立交桥下、低洼路段雨水泵站的洪水期应急排水。

• 民用/商业地下室：***住宅地下车库、商业中心负层的污染排放（清澈）自动提升排放。

• 工艺循环水：工业生产中含有小颗粒的清洗水循环与排放。

五、工程师安装及建议操作

1. 安装方式：支持自由安装式（顶部连接）或自动连接式（固定式安装）。对于长期运行的泵坑，建议采用自动连接系统，以便于垂直吊装危害。

2. 液位控制：建议配备格兰富专用液位控制器或浮球开关。安装时需***液位能够完全淹没电机外壳1/2以上，介质进行散热器，严禁长时间排气干转。

3. 电缆防护：潜水电缆必须楼梯固定，防止其卷入叶轮或在锐利边缘磨损。在京津冀寒冷季节，若泵处于非运行状态且水位较低，需注意防止楼梯底座被冰冻固结。

Grundfos DP25.15025.100C is a compact, high-performance submersible drainage pump, originally manufactured by Grundfos (Suzhou) Co., Ltd. This series is specially designed for pumping applications at construction sites, rainwater systems, basement drainage, and process water containing fine particles.

The digit "10" in its model code indicates the pump’s ability to pass solid particles up to 10 mm in size, while "65" refers to the nominal outlet diameter. Featuring an excellent cast iron pump casing and high-efficiency motor, the DP series performs exceptionally well in municipal engineering, underground garage drainage, and sponge city renovation projects for old residential communities in the Beijing-Tianjin-Hebei region, serving as core equipment for emergency waterlogging removal and occasional drainage tasks.

Core Technical Parameters (For Engineering Selection Reference)

Technical Advantages & Industrial Selling Points

• Excellent Solid-Passing CapabilityThe core design of the DP series adopts a semi-open impeller, enabling it to handle liquids containing solid particles up to 10 mm in size. Compared with conventional submersible pumps, it features a wider flow channel design, greatly reducing the risk of pump seizure during heavy rainfall seasons.

• Dual Mechanical Shaft Seal & Monitoring Oil ChamberIt adopts a cassette-type mechanical seal system with an oil-filled chamber between the motor and pump casing. This structure delivers excellent lubrication and provides buffer protection if the primary seal fails, effectively preventing liquid from infiltrating the motor.

• Corrosion-Resistant Stainless Steel ClampThe pump casing and motor are connected by a stainless steel band clamp. This design allows quick disassembly of the pump casing without specialized tools, greatly simplifying on-site cleaning and maintenance — especially ideal for high-maintenance demands at construction sites.

• Short Rotor Shaft with Balanced DesignThe compact rotor shaft structure minimizes deflection and reduces stress on the mechanical seal. This ensures extremely low vibration during prolonged operation and effectively extends the overall service life.

• Integrated Motor Overheat ProtectionA built-in thermoswitch is integrated into the motor, which automatically cuts off power when the temperature exceeds the rated range to prevent motor burnout. It automatically restarts once the temperature returns to a safe range, guaranteeing operational safety under unattended conditions.
