PGW series Single Suction Centrifugal Pump

Short Description:

PGW energy-saving pipeline circulation pump is a new generation product designed based on the performance parameters specified by the company’s standards and combined with years of production experience of our company. The product series has a flow range of 3-1200 meters per hour and a lift range of 5-150 meters, with nearly 1000 specifications including basic, expansion, A, B, and C cutting types. According to the different media and temperature used in different situations, changes in the material and structure of the flow passage part, PGL hot water pumps, PGH stainless steel pipeline chemical pumps, and PGLB sub explosion-proof pipeline oil pumps with the same energy parameters are designed and manufactured, making the use of this series of products popular and completely replacing conventional centrifugal pumps used in all occasions.

Product Application

1. Working conditions:
① Working pressure ≤ 1.6MPa, can be determined according to order requirements in special environments; ② The maximum temperature of the enclosure shall not exceed 40 ℃, and the relative humidity shall not exceed 95%; ③ Transport medium value 5-9, medium temperature 0 ℃ -100 ℃; ④ Stable delivery medium solid volume ratio ≤ 0.2%.
2. Application field
Water pumps should be used for cold and hot water transportation, pressurization, and circulation systems; 1. Pipe network pressurization 2. Circulating water supply 3. Agricultural irrigation 4. Heating, ventilation, and refrigeration 5. Industrial water 6. Boiler protection water replenishment 7. Fire water supply
Note: In order to ensure the safe and efficient operation of the water pump, the operating point should be used within the specified performance range of the water pump.
3. Conveyed liquid
The liquid conveyed should be clean, low viscosity, non explosive, and free from solid particles and fibrous substances that cause mechanical or chemical damage to the water pump.
Cooling liquid, common surface water, softened water and domestic hot water of general industrial boiler Hydronics (the water quality shall meet the standard requirements of relevant hot water supply system).
If the density and viscosity of the liquid conveyed by the pump are greater than that of ordinary clean water, it will cause the following situations: a significant decrease in pressure, low hydraulic performance, and a significant increase in motor energy consumption. In this case, the water pump must be equipped with a higher power motor. Please contact the company’s technical service department for specific information.
For conveying liquids containing minerals, oils, chemical liquids, or other liquids that are different from clean water, “O” type sealing rings, mechanical seals, impeller materials, etc. should be selected accordingly according to the situation.
