The Lowara HM, HMS and HMZ Series of horizontal multi-stage centrifugal pumps have been replaced by the e-HM Series. These pumps have been specifically designed for residential applications. The new design features:
• The latest in hydraulic systems and efficiency to ensure low operating costs and a 30 per cent energy saving compared with earlier models.
• High-quality bearings, together with a thick sheet metal casing.
• A heavy-duty metal pump body to minimise noise.
The e-HM residential pump is able to ensure a consistent and reliable supply of water to most domestic buildings, from single family homes to ten-floor apartment blocks. It is made from AISI 304 and 316 stainless steel with mechanical face seal and O-ring options. There are four versions available:
• A Bare pump.
• An on-off system combined with a pressure switch and a pressure tank.
• A semi-constant pressure system with a Genyo brand electronic pump control.
• Teknospeed variable speed control and a constant pressure system.
Specifications
• Liquid delivery of up to 29 cubic metres per hour.
• A maximum head of 160 metres.
• Single and three-phase 50 / 60 Hz power supply.
• A power rating that ranges from 0.3 kW to 5.5 kW.
• A maximum operating pressure of 16 bar.
• The temperature range of the pumped liquid should range from -10 degrees C to +120 degrees C.
There is a wide range of configurations available so that the pump can meet specific domestic applications, such as water supply and pressure boosting to heating, ventilation and air conditioning. The e-HM Series can also be used in:
• Industrial washing and cleaning.
• Washing machines, including car washing.
• Water treatment such as ultra and nano-filtration systems and softening, demineralisation and ionising systems.
