Single-stage single-suction centrifugal pump is in Germany Thomas (Thomas) on the basis of advanced technology, the use of international common centrifugal pump performance parameters, developed a new generation of energy-saving, environmentally friendly horizontal centrifugal pump. The series of pump performance, high reliability, long life, reasonable structure, beautiful appearance, with industry-leading level.

The main purpose

1, for the delivery of water and physical and chemical properties similar to other liquids used in water, for industrial and urban water supply and drainage, high-rise building pressurized water, garden irrigation, fire booster, long-distance transport, HVAC refrigeration, Heating and water cycle pressurization and equipment support, the use of temperature T ≤ 80 ℃.

2, apply to: metallurgy, chemical, textile, paper, and hotel hotels such as boiler hot water pressurized circulation and urban heating system, the use of temperature T ≤ 120 ℃.

3, for the transport of non-solid particles, corrosive, viscosity similar to the liquid water, for petroleum, chemical, metallurgical, power, paper, food and synthetic fiber and other departments, the use of temperature -20 ~ 120 ° C.

4, for the delivery of gasoline, kerosene, diesel and other oil products or flammable, explosive liquid, the medium temperature is a 20 ~ C ~ +120 ℃.

Working conditions

1, suction pressure ≤ 1.6MPa, or pump system maximum working pressure ≤ 1.6MPa, that is, pump inlet pressure + pump head ≤ 1.6MPa, pump static pressure test pressure of 2.5MPa. Pump system working pressure greater than 1.6MPa should be made in the order, so that in Germany Thomas (Thomas) factory manufacturing pump part of the flow and the connection part of the use of cast steel.

2, ambient temperature <40 ℃, relative humidity <95%.

3, the volume of solid particles in the transport medium does not exceed 0.1% of the volume per unit volume, particle size <0.2mm.

Note: If the use of media with a small particle, please specify when ordering, so that manufacturers use wear-resistant mechanical seal.

Features

1, smooth operation: the absolute axis of the pump concentricity and impeller excellent static and dynamic balance, to ensure smooth operation, no vibration.

2, water leakage: different materials, carbide seal, to ensure that no leakage of different media delivery.

3, low noise: two low-noise bearings under the support of the pump, running smoothly, in addition to the motor faint sound, basically no noise.

4, the failure rate is low: the structure is simple and reasonable, the key part of the use of world-class quality; matching, machine trouble-free working hours greatly improved.

5, easy maintenance: replacement seals, bearings, simple and convenient.
