HMS Stainless Steel Single-Stage Centrifugal Pump

Structure features:

8HMS/HMSS series of pump is single-stage centrifugal pump and features axial suction and radial discharge;
8Compact structure, the pump is directly connected with the motor, coaxial installation;
8Convenient installation,screw thread water inlet and outlet;
8Light weight, thin plate pressing structure for main parts and components;
8A little corrosion resistance, material of wet parts is AISI304 or AISI316 stainless steel.

Applications:

8Pressurization and pumping of industrial and civilian clean water or other liquids;
8Water treatment;
8Water circulating system;
8Agricultural irrigation;
8Other fields. 

Pumping liquids:

8Thin, clean, non-flammable and explosive, not containing the liquid with solid particle and fiber;
8Able to transmit light corrosive medium (Relate to the content of chloride ion in the medium, thickness of acid or alkali, whether generate corrosion on the rubber and mechanical seal materials);
8The density of transmitted medium is less than that of clean water, viscosity close to that of water. Other wise the motor of large power is required.


Operating condition:

8Max. pressure of the system: 8bar ;
8Liquid temperature:  -10℃ to +85℃;
8Ambient temperature: up to +40℃;
8Altitude: up to 1000m.


Motor:

8TEFC motor, 2-pole;
8Protection class: IP55;
8Insulation class: F;
8Standard voltage: 50HZ  1 x 220V
                                                 3 x 380V x 220V
8Standard voltage: 60HZ  1 x 220V
                                                  3 x 380V x 220V

Installation requirements:

8The pump shall be fastened on the stable horizontal base ;
8The installation of the pump shall ensure that the pump will not be influenced by the tension of the pipeline;
8The pump shall be installed on the ventilating and anti-freezing place to ensure normal operation of the motor;
8Electric wiring device shall guarantee that the pump will not be damaged by lack of phase, unstable voltage, surrent leskage and overload .

Curves:

Include performance curve in the technical data:
8All curves are based on the measured values of 50Hz;constant motor speed 2850r/min, 60Hz;constant motor speed 3450r/min;
8Measurement id done with 20℃ air-free water, kinematic viscosity of 1mm²/sec;;
8Curve tolerance in conformity with ISO9906 Annex A;
8The operation of pump shall refer to the performance region to prevent overload of motor due to too large flow rate.
