The pump has a hybrid design, which enables it to withstand pressure of up to 3 bars, and is made of bronze, high-strength glass-fibre-reinforced polypropylene and polyamide. Its service life has been extended by fitting it with larger shafts and bearings, and the pump and the motor also have a shared shaft featuring additionally strengthened bearings. The fixed bearing is reinforced and designed for long-lasting service.
Herborner says that the pumps can help minimise energy consumption and CO2 emissions. Depending on requirements, the pump can be powered by a high efficiency IE2 motor, a permanent magnet motor (PM), a single-phase motor up to 2.2 kW or an NEMA motor for the American market. PM motors save considerable amounts of energy and increase the efficiency level by up to 13%, according to Wolfram Kuhn, president of Herborner Pumpenfabrik.
