DRL
Constant Pressure Frequency Conversion Water Supply Equipment
The DRL series booster systems are designed with vertical multistage pumps. The pumps are mounted on MS skid with headers as per flow and pressure requirements. A pressure tank of suitable volume is also mounted on a skid or connected separately.
Three different varieties in this series:
• DRL - F series: with fixed speed controller panel
• DRL - V series: with variable speed drive controller panel
• DRL - I series: with VFD mounted on pump itself
• Head: up to 300 m
• Flow range: up to 500 m³/h
• Temperature of pumped liquid: -15 ~ 70°C
Applications
• Industrial water supply: High rise buildings, home complex and villas
• General public: Hospital, school, gym, golfing coutroom and airport
• Business oriented building: Hotel, buisness building, department store
• Irrigation: Amusement park, orchard, farm
• Producing industry: Textile mfg, food industries and plants
• Manufacturing industry: Washing device, food industry, factory
Features and advantages
The DRL systems are designed for higher flows and medium to high pressures. However by splitting the total flow & adding more pumps, one can reduce the power consumption.
Each DRL systems offers different advantages and features such as comfort level, initial investment cost, ease of operation, free from pressure shocks and water hammering in the pipe line, etc.
Key features:
• All the wet parts are made of 304 stainless steel
• Energy efficient
• Constant water pressure
Working conditions
They are designed for pumping clean, explosion-proof, non-flammable liquids that are non-aggressive to the material used in the pump construction and do not contain solid or fibrous inclusions.
• Temperature of pumped liquid: -15 ~ 70°C
• Altitude above sea level: up to 1000 meters
• Ambient temperature: up to 40°C
• Liquid pH range: 5 ~ 9
• Input voltage: 220 ~ 480V
