GRG50-125A stage single suction pipeline pump GRG50-125A pipeline pump is a single-stage single-suction pipeline pumps, vertical structure, import and export of the same caliber, easy installation and maintenance, without the need to open pipeline system; mainly used for industrial and urban water supply and drainage, requiring ambient temperature <40 ° C, relative humidity <95%, the principle is the basis of the general vertical pump clever combination of the design. Flow: 11m3 / h Head: 16m Features: pump for the vertical structure, import and export of the same caliber, and in the same center line, like the valve installed in the pipeline, with a mounting foot, increasing the stability of the pump sex, compact appearance, small footprint, construction investment is low. Impeller mounted directly on the motor shaft extension, the short axial dimension, compact structure, reasonable configuration of pump and motor bearings, can effectively balance the radial and axial loads generated by operation of the pump, thus ensuring the smooth operation of the pump, vibration noise low. Seal mechanical seal or a combination of mechanical, using imported titanium alloy seal ring, medium and high temperature mechanical seal with carbide materials, wear-resistant seal, can effectively increase the mechanical seal life. Easy installation and maintenance, without the need to open pipeline system, simply remove the pump body nut out all the rotor components. Flow and head requirements that need the use pumps in series or parallel operation according to the requirement. The pump may be employed in accordance with requirements of piping layout vertical and horizontal installation. Main purpose: IRG (GRG) Hot Water (heat) circulation pump is widely used in energy, metallurgy, chemicals, textiles, paper, as well as hotels and restaurants and other high-temperature hot water boilers pressurized circulation of urban heating system circulating pump, IRG use Temperature T: ≤120 ° C, GRG temperature T: ≤240 ° C. Working conditions: suction pressure ≤1.0Mpa, or maximum working pressure pump system ≤1.6Mpa, pump suction pressure + pump head ≤1.6Mpa. Hydrostatic test pump pressure 2.5Mpa. Please specify when ordering system work pressure. Greater than 1.6Mpa working pressure pump system should be made when ordering separately, in order to manufacture the pump flow portion and a coupling portion using steel materials. Ambient temperature <40 ° C, relative humidity <95%. The transmission medium solids volume content not exceeding 0.1% of unit volume, particle size <0.2mm. Product Principle: GRG single stage single suction vertical pipeline centrifugal pump, the pump is scientific and technical personnel in the United Nations expert selection of domestic hydraulic model, the IS-type centrifugal pump performance parameters, a clever combination of design and manufacturing on the basis of the general vertical pump while depending on the temperature, medium derived on the basis of GRG vertical pipeline centrifugal pump on the hot water pipes, heat pipe pump, corrosive chemical pump, oil pump and other products, GRG pipeline pumps with high efficiency, low voice , performance and reliability.
