• Teknospeed GTKS: GTKS, TKS and HVW (HYDROVAR WATERCOOLED) – Series of Variable Speed Electric Pumps and Pressure Booster Units The single-phase Hydrovar Watercooled and Teknospeed variable speed electric pumps are designed for residential applications as they provide all the comfort and advantages of constant pressure in the home. The Teknospeed series comprises a frequency converter integrated into the pump which adjusts motor speed so as to constantly provide users with the same pressure, even when demand for water changes The range features a large number of models and pump types: • Horizontal pumps: HVW/HMZ, HVW/BG, HVW/CEA-CA. • Horizontal and vertical pumps: TKS/HMZ, TKS/BG, TKS/CEA-CA, TK/SV. • Single pump or two-pump pressure booster units: GTKS20/HMZ, GTKS20/BG, GTKS20/CA, GTKS20/SV e-SV: Highly reliable and technologically advanced multipurpose pump capable of satisfying the needs of a wide variety of users. Many different construction designs are available, with models featuring 1-3-5-10-15-22-33-46-66-92-125 m3/h nominal capacities. All >= 1.5kW are equipped with IE3 standard motors. New design features: • Balanced mechanical seal replaceable with out need for pump disassembling (for 10-15-22SV>=5,5kW, 33-46-66-92-125SV) • “O” Ring seat design to allow for simple outer sleeve disassembly • Floating for self alignment replaceable diffuser wear ring (PPS Glass filled tecnopolymer to withstand chemically corrosive, mechanically aggressive and high temperature liquids) • Reduced impeller axial thrust for longer standard motor bearing life (17,500h) • Hard Material Intermediate bush bearing (Tungsten Carbide/Silicon Carbide) to improve life and ability to withstand heavy duty applications, like boiler feeding • High temperature seal option (180°C max) with low NPSH design, high pressure design (up to 40 Bar), and passivated & electro-polished version are available upon request. Further unique features of the e-SV include the integration of performance diagnostic devices such as the i-Alert™ vibration monitor and Dry Run sensor. The i-Alert™ and the Dry Run sensor are available as an accessory for all models.
