TD
Vertica in-line circulation pumps
The TD series pumps are vertical single-stage circulation pumps with in-line connections. The pumps are designed to be removed from the pipeline without requiring disassembly of system components. At low pressure, these pump is capable of providing high productivity.
• Power: 0.37 ~ 110 kW
• Head: 4.5 ~ 108 m
• Flow range: 7 ~ 900 m³/h
• Temperature: -15 ~ 110°C
Applications
The TD pumps are applicable for urban water supply, cooling systems, industrial water, and hot and cold water for regional heat supply systems.
• Water treatment ultrafiltration system
• Circulation circuits of boiler houses
• Central heating points
• Booster pumping station for central heating systems
• Process cooling circulation circuits (cooling towers-heat exchangers)
• Air conditioning circulation systems (chiller-fan coil)
• Can be used in fire extinguishing and pressure boosting systems
Features and advantages
The pump unit consist of a flow part and a vertical asynchronous electric motor. The connection of the motor shaft and the flow part can be implemented in several ways, depending on the size:
• TD32~TD150: extended design of the flow part shaft
• TD200~300: connection with a coupling
The suction discharge pipes are located coaxially at the same height relative to hte pump base "in-line", which allows for maintenance without complete disassembly of the hydraulic system. The main elements of the flow part are: a closed-type impeller made by casting; a pump body (cast-iron), including a supply and discharge device (spiral discharge); a pump shaft made of stainless steel ; an end seal.
Working conditions
The WQ pump are suitable for pumping media with temperatures up to 40°C, a hydrogen intex (pH) from 4 to 10 and a density of no more than 1200 kg/m³. The mass fraction of solid mechanical impurities should not exceed 2%.
The maximum diameter of solid particles must not exceed the free passage values of particles specified in the technical specifications of the pumps.
For pumping working media with a high content of fibrous inclusions, it is recommended to use WQ-W series pumps with a cutting impeller.
Electric motor
A three-phase asynchronous electric motor is used as a drive for the pumping unit.
