             GRS型泵为卧式径向剖分，后开门，单级单吸蜗壳式离心泵。泵的连接尺寸按照ISO2858/DIN 24256，脚支撑式。
          GRSY、GRY为卧式，径向剖分，后开门，单级单吸蜗壳式离心泵。泵连接尺寸按照ISO2858/DIN 24256，中心线支撑式。

英国GRIMM格林进口热水循环泵性能特点：
1、轴封：可选配软填料密封和机械密封。  
2、联轴器：采用弹性柱梢联轴器，传动精度高。  
3、辅助管路：按API 610第8版要求配置。  
4、承压：设计压力为4.0MPa，承压高。  
5、轴承：轴承选用圆柱滚子轴承与两个角接触轴承配套，采用稀油润滑，承载能力显著提高。轴承设计寿命25000小时。  
6、高效节能：采用CFD计算流体动力学，分析计算出泵内压力分布和速度分布关系、优化泵的流道设计，确保泵有高效的水力形线，提高了泵的效率。  
7、耐高温结构：泵体采用中心支撑方式，解决了泵在输送高温介质时防止高温下泵组热膨胀不一致而造成的应力集中以及联轴器对中心发生改变。泵支架、泵盖、悬架体(轴承部位)及机封压盖均有冷却腔，可在不同温度时分别用冷却水冷却或风冷却。

           GRS pump is horizontal radial split, back door, single stage single suction volute centrifugal pump. Pump connection size according to ISO 2858 / DIN 24256, foot support type.

        GRSY and GRY are horizontal, radial split, back door, single stage single suction volute centrifugal pumps. Pump connection size according to ISO 2858 / DIN 24256, central line support type.

UK GRIMM Imported hot water circulating pump performance characteristics:

 

 

1.Shaft seal: optional with soft packing, sealing and mechanical seal.

2.Coupling: the use of elastic column pin coupling, high transmission accuracy.

3.Auxiliary pipe: according to API 610, Eighth Edition requirements configuration.

4.Pressure: design pressure of 4.0MPa, high pressure.

5.Bearings: Bearings selected cylindrical roller bearings and two angular contact bearings matching, the use of thin oil lubrication, bearing capacity improved significantly. Bearing design life 25000 hours.

6.High efficiency and energy saving: use CFD computational fluid dynamics to analyze and calculate the pressure distribution and velocity distribution in the pump, optimize the flow passage design of the pump, ensure the efficient hydraulic line of the pump, and improve the efficiency of the pump.

7.High temperature structure: pump body using the center support way, solve the pump in the transmission of high temperature medium, prevent high temperature under the pump group thermal expansion inconsistent stress concentration, and the coupling to the center change. Pump support, pump cover, suspension body (bearing parts) and machine seal gland have cooling chamber, can be used at different temperatures with cooling water cooling or wind cooling.
