North Ridge NMTD MAX Series Energy Saving Inline Twin Circulating Pumps For Liquid Glycol

NMTD MAX Series Energy Saving Inline Twin Circulating Pumps Flow RateUp to 72.7m³/hrHead (Pressure)Up to 18.9mInlet/Outlet Sizes1 1/2" to 4"Operating Temperature-10°C to +110°CDrive OptionsElectric Motor The NMTD MAX series of high efficiency inline twin circulating pumps are designed for applications involving hot and cold water, these include industrial and civil heating systems, air conditioning, HVAC and closed-circuit cooling. Pumped fluids must be clean, free of oils, contain no solids and be non-flammable. Compatible fluids include; hot water, cold water and water and glycol mixtures (check compatibility with glycol concentrations over 20%). The acceptable fluid temperature range is between -10°C and 110°C, the ambient environmental temperature must not exceed 40°C. The NMTD MAX range is fitted with a cutting-edge high efficiency motor that reduces energy consumption during operation. The control module has 5 easily selected modes depending on system requirements, these are: Automatic mode - The pump automatically selects the operating pressures depending on the system. This is the recommended operating mode for most systems as the pump finds the optimum operating pressure. Proportional pressure - The pump will maintain pressure depending on the required flow rate. Constant pressure - The pump will maintain the pre-set pressure. Constant speed - The pump will maintain the pre-set speed (RPM). Night mode - Night mode can be used in conjunction with any of the above modes. The pump will reduce flow, pressure and power consumption when it detects that the liquid temperature has decreased by 15-20°C. The pump will automatically return to normal operating model when the temperature rises. Additionally, the NMTD MAX series can be fitted with a communication module for remote control (NMTD MAX C version). The communication module allows for various remote-control features, including: •Remote On/Off•Analogue 0-10V voltage control•MODBUS remote control•Status relay feedback•Web access via Ethernet Standard materials are: Pump casing - Cast ironImpeller - PESShaft - Stainless steel AISI 316Bearings - GraphiteRotor can - Stainless steel AISI 316 This range is also available with a single cast iron pump (NMT MAX range). This range is also available with a single bronze pump casing for hot water sanitary applications (NMT SAN MAX range).
