WTM is multi-purpose pump suitable for a variety of different applications demanding reliable and cost-efficient supply. WTM pumps are used in five main fields of application.
Water Supply
Besides general water supply in municipal and industrial water works the WTM pumps are used for these specific applications.
• Filtration and transfer at water works
• Pressure boosting in mains
• Pressure boosting in high-rise buildings, hotel, etc. • Pressure boosting in industrial buildings
• Various swimming bath applications
Industrial pressure boosting
• Industrial washing and cleaning systems • Industrial wash downs systems
• Vehicle washing tunnels
• Fire-fighting systems

Industrial Liquid Transfer
• Cooling and air-conditioning systems • Boiler-feed and condensate systems
• Aqua farming
• Industrial heating systems
• District heating plants

• Heating Systems
• Ventilation systems
• Air-conditioning systems

• Field irrigation
